No, Builders’ Risk insurance does not cover the cost to repair or replace faulty workmanship itself. The policy does cover resulting damage that happens when faulty workmanship causes harm to other parts of the insured project. Specific policy language and endorsements like LEG 3 can expand this coverage significantly.
The exclusion for faulty workmanship exists because of the insurance industry’s business risk doctrine. This doctrine states insurers do not provide warranty coverage or guarantee work quality. Courts across U.S. jurisdictions since the 1970s have upheld this boundary: liability insurance protects against accidents and unforeseen events, not poor business practices or defective work product. Contractors bear full financial responsibility for redoing work they performed incorrectly—forcing them to absorb costs that can range from thousands to millions of dollars.
According to recent data, approximately 30 percent of overall construction work is actually rework. This translates to billions in annual losses nationwide. Understanding faulty workmanship coverage becomes critical for every construction stakeholder—from property owners to general contractors to subcontractors.

What Builders’ Risk Insurance Actually Protects During Construction
Builders’ Risk insurance is a specialized form of property insurance for buildings and structures during construction or renovation. Coverage activates the moment materials arrive at the job site and continues until the project reaches substantial completion or occupancy. The policy operates as an all-risk or special perils form, meaning it covers all causes of loss except those specifically excluded in writing.
Property owners, general contractors, subcontractors, lenders, and architects all need this coverage. State courts have consistently held that anyone with an insurable interest can be named as an insured under a Builders’ Risk policy. This shared coverage model reflects the construction industry’s collaborative nature. A loss impacts multiple stakeholders at once.
Builders’ Risk policies cover structures under construction, materials stored on-site or in transit, temporary structures, equipment used to service the building, and sometimes soft costs like loan interest and permit fees. The ISO CP 00 20 form, used by many insurers as a template, defines covered property to include foundations, fixtures, machinery, and building materials intended for permanent installation. Coverage terminates when construction completes, the building is occupied, or the policy expires—whichever occurs first.
Why Insurers Refuse to Cover Your Defective Work
The fundamental reason Builders’ Risk policies exclude faulty workmanship stems from the business risk doctrine in case law dating back decades. This legal principle holds that liability insurance protects against fortuitous events—accidents that occur by chance—not predictable business failures. When a contractor performs work incorrectly, courts reason, this constitutes a breach of contract rather than an insurable risk.
The Ohio Supreme Court articulated this principle clearly in Westfield Insurance Co. v. Custom Agri Systems. The court stated that faulty workmanship claims are not fortuitous in the context of liability policies. Courts distinguish between two types of risk: the risk that work will be performed improperly (business risk, not covered) and the risk that defective work will cause injury to people or damage other property (liability risk, covered). The former falls outside insurance coverage because contractors are expected to guarantee their own work quality.
This doctrine applies equally to Builders’ Risk policies, though with nuanced differences. While Commercial General Liability policies focus on third-party claims, Builders’ Risk addresses first-party property losses during construction. The exclusion language typically reads: “This policy does not insure the cost of making good faulty workmanship, construction materials or design.” If a subcontractor installs a roof improperly and it must be torn off and replaced, the policy excludes the cost of that replacement.
Decoding the Faulty Workmanship Exclusion in Your Policy
Standard Builders’ Risk policies contain exclusion clauses that specifically address faulty workmanship, defective materials, and design errors. The typical exclusion language states: “Loss or damage caused by or resulting from faulty or defective design, specifications, workmanship, repair, construction, materials used in construction, renovation, remodeling, or grading.” This broad language excludes multiple types of defects at every stage of construction. Insurers argue they cannot effectively underwrite subjective standards of workmanship quality across thousands of trades and techniques.
Courts have upheld this reasoning, noting that insurers are not warrantors or guarantors of their insureds’ products or services. The exclusion’s purpose is to prevent the Builders’ Risk policy from becoming a performance bond or quality guarantee. Most policies include crucial exception language immediately following the exclusion. A common exception reads: “Unless physical damage not otherwise excluded by this policy results, in which event this policy shall insure such resulting damage.”
This ensuing loss or resulting damage provision creates the critical distinction between excluded and covered losses. While the defective work itself remains uncovered, damage that flows from that defect to other parts of the project may be covered—if you can prove causation and separation. The burden falls on the insured to demonstrate that damaged property is physically separate from the defective work.
The Ensuing Loss Loophole: When Your Insurer Must Pay
The ensuing loss provision represents the most important coverage trigger in faulty workmanship scenarios. This exception restores coverage for losses that result from excluded perils, provided the resulting damage stems from a separate and independent covered cause. The provision functions as a two-step analysis: first, determine if the initial cause is excluded; second, determine if subsequent damage qualifies as resulting or ensuing loss.
Courts interpret this language by examining whether the damage represents a distinct loss from the faulty work itself. In Swire Pacific Holdings v. Zurich Insurance, the Florida Supreme Court explained that ensuing loss means damage occurring subsequent to, and as a result of, an excluded peril. The damage must be physically separate from the defect. The damage must arise from a chain of causation that includes a covered peril.
Suppose an electrical subcontractor improperly installs wiring in a mechanical room, creating a fire hazard. When the faulty wiring sparks and triggers the building’s fire suppression system, water cascades throughout the structure causing widespread damage. The ensuing loss provision operates as follows: the cost to replace the defective wiring is excluded, but water damage to drywall, flooring, and other components is covered because fire and water are covered perils. Coverage determination becomes highly fact-specific, leading to litigation in approximately 20 to 30 percent of construction defect claims.
The Supreme Court Case That Rewrote the Rules
In 2016, the Supreme Court of Canada issued Ledcor Construction Ltd. v. Northbridge Indemnity Insurance Co., fundamentally altering how courts interpret faulty workmanship exclusions. The case involved a newly constructed office tower in Edmonton where a cleaning company, Bristol, damaged windows by using inappropriate tools and methods during construction clean. The windows required complete replacement at a cost of $2.5 million.
Station Lands (the owner) and Ledcor (the general contractor) claimed coverage under their all-risk Builders’ Risk policy. The insurers denied the claim based on an exclusion for “the cost of making good faulty workmanship” unless “physical damage not otherwise excluded” resulted. The insurers argued the damaged windows represented the cost of fixing Bristol’s faulty cleaning work. The plaintiffs countered that the windows themselves sustained resulting damage.
The trial court found the exclusion ambiguous and ruled for the insureds using the doctrine of contra proferentem, which requires ambiguous insurance contracts construed against the drafter. The Alberta Court of Appeal reversed, finding the exclusion unambiguous and clearly excluded the window replacement cost. The Supreme Court of Canada overturned the Court of Appeal, restoring the trial court’s finding of coverage. Justice Wagner, writing for the unanimous Court, held that the purpose of Builders’ Risk policies is to provide broad coverage for projects while under construction given their susceptibility to loss.
The Court stated the faulty workmanship exclusion only excludes the cost of redoing the faulty or inadequate work and does not bar recovery for damaged property that must be replaced. Courts must construe exclusions narrowly and exceptions broadly to give effect to the policy’s protective purpose. This decision created a major expansion of coverage interpretation across North American jurisdictions.
| Case Element | Outcome and Impact |
|---|---|
| Damaged Property | Windows scratched during cleaning; $2.5M replacement |
| Insurer Position | Entire loss excluded as faulty workmanship cost |
| Insured Position | Windows sustained resulting damage; exception applies |
| Supreme Court Ruling | Coverage applies; exclusion limited to defective cleaning |
| Long-term Effect | Broader interpretation; insurers need clearer exclusion language |
LEG Clauses: Three Levels of Protection You Need to Understand
The London Engineering Group, an association of insurers and underwriters, developed three standardized exclusion clauses addressing defects in construction projects. These LEG clauses—numbered LEG 1, LEG 2, and LEG 3—offer progressively broader coverage. They have become increasingly common in U.S. Builders’ Risk policies, particularly for large commercial and infrastructure projects exceeding $100 million in value.
LEG 1/96 provides the narrowest coverage by excluding all loss or damage “due to defects of material, workmanship, design, plan or specification.” LEG 1 excludes both the defective work and any resulting damage to other property. Under this provision, a defective concrete batch that damages an entire floor system would be completely excluded—both the concrete and the damaged structural elements. LEG 1 offers less protection than typical U.S. Builders’ Risk policies with standard ensuing loss provisions.
LEG 2/96 creates a middle-ground approach excluding costs that would have been incurred to remedy the defect immediately prior to damage occurring. This creates a hypothetical time bar that distinguishes between preventive costs (excluded) and damage-repair costs (covered). If structural steel is installed incorrectly but not discovered until a collapse occurs, LEG 2 excludes what it would have cost to fix the steel before collapse but covers additional damage. The practical effect functions like an access cost exclusion because the hypothetical pre-damage repair cost often approximates actual post-damage costs.
LEG 3/96 or LEG 3/06 provides the most comprehensive protection by covering defects in material, workmanship, design, plan, or specification. LEG 3 excludes only “costs incurred to improve the original material, workmanship, design, plan or specification.” If defective concrete requires replacement, LEG 3 covers full replacement cost unless the new specification constitutes an upgrade. LEG 3 transforms Builders’ Risk into nearly comprehensive quality coverage, though disputes over what constitutes improvement frequently arise.
| LEG Version | What You Get |
|---|---|
| LEG 1 | No coverage for defects or resulting damage |
| LEG 2 | Covers damage minus hypothetical pre-loss remedy costs |
| LEG 3 | Covers all defect costs except upgrades |
When Your Defective Foundation Gets Covered (And When It Doesn’t)
A concrete subcontractor improperly mixes a batch of concrete for a building’s foundation, using excess fly ash that compromises the concrete’s compressive strength. Engineers discover the defect during routine testing before the building reaches substantial completion. The defective foundation must be demolished and re-poured, requiring extensive shoring of the superstructure while corrective work proceeds. This scenario represents one of the most common faulty workmanship claims contractors face.
| Cost Category | Coverage Decision |
|---|---|
| Removing and replacing defective concrete | EXCLUDED – cost of making good faulty workmanship |
| Structural engineering analysis to assess damage extent | EXCLUDED – investigation costs related to defect |
| Shoring entire building during foundation repair | COVERED under LEG 3; EXCLUDED under standard policy |
| Damage to electrical and plumbing rough-in during demolition | COVERED – resulting damage to completed work |
| Delay costs including loan interest during 4-month repair | COVERED if soft costs endorsement purchased |
Without LEG 3 coverage, the insured bears the majority of repair costs. The Archer Western v. Ace case in Florida involved nearly identical facts, with a bridge project requiring repair of concrete components containing excessive fly ash. The court denied summary judgment for the insurer, finding disputed facts about whether the concrete sustained damage triggering coverage. Even clear exclusion language generates expensive litigation.
What Happens When Faulty Roofing Causes Water Intrusion
A roofing contractor fails to properly install flashing around roof penetrations, violating manufacturer specifications and building code requirements. Three months after the building opens, heavy rains cause water to infiltrate through the defective flashing. The water damages drywall, insulation, flooring, and stored inventory in multiple tenant spaces. Mold growth begins in wall cavities within ten days.
| Cost Category | Coverage Decision |
|---|---|
| Tearing off and replacing improperly installed flashing | EXCLUDED – cost to correct original faulty workmanship |
| Water damage to drywall, insulation, and flooring | COVERED – resulting damage from covered peril |
| Mold remediation in affected wall cavities | COVERED if policy includes mold coverage |
| Damage to tenant’s stored inventory | EXCLUDED – tenant’s property not covered |
| Business interruption losses for closed tenant spaces | EXCLUDED – covers project property, not operations |
This scenario demonstrates the ensuing loss provision’s operation. The initial faulty work (improper flashing installation) is excluded, but subsequent water damage constitutes a separate loss from a covered peril. The insured recovers costs for water damage repairs but absorbs the cost to correct the original defective roofing work. Many policies exclude or limit mold to $10,000-$50,000, creating additional exposure.
How Defective HVAC Installation Triggers Coverage
A mechanical contractor installs an HVAC system but fails to properly balance the system or install vibration isolation pads. When the system operates, excessive vibration damages structural connections, cracks concrete floors, and breaks water supply lines. The system itself requires significant modifications to operate within specifications. Multiple coverage determinations apply to this single defect scenario.
| Cost Category | Coverage Decision |
|---|---|
| Redesigning and modifying HVAC system | EXCLUDED – cost to correct defective installation |
| Repairing structural connections damaged by vibration | COVERED – resulting damage to other components |
| Repairing cracked concrete floors | COVERED – direct physical loss from vibration |
| Water damage from broken supply lines | COVERED – water damage from pipe break |
| Testing, commissioning, and rebalancing system | EXCLUDED – costs related to fixing original work |
Builders’ Risk covers collateral damage to the project from defective work but not the defect itself. Contractors face partial recovery, recovering some costs while self-insuring others. The principle that emerges is clear: demonstrate physical separation between the defect and the resulting damage to maximize recovery.
Critical Differences Between CGL and Builders’ Risk Coverage
Contractors often hold both Commercial General Liability insurance and Builders’ Risk coverage. These policies serve fundamentally different purposes with distinct coverage for faulty workmanship. Understanding these differences prevents costly gaps.
CGL policies protect against third-party liability claims for bodily injury and property damage. The ISO CGL form includes two critical faulty workmanship exclusions: Exclusion j(5) bars coverage for property damage to “that particular part of any property on which you are working” if the damage arises from the work. Exclusion j(6) excludes “that particular part of any property that must be restored, repaired or replaced because your work was incorrectly performed on it.” CGL policies include a crucial subcontractor exception to Exclusion j(6) that restores coverage for damage to the insured’s work arising from work performed by subcontractors.
Builders’ Risk provides first-party property coverage protecting the project itself during construction. Unlike CGL, which requires proof of liability to a third party, Builders’ Risk operates on a no-fault basis. It does not matter who caused the loss. If a covered peril damages covered property, the policy responds. The Builders’ Risk policy protects materials, work in progress, temporary structures, and the building under construction.
CGL covers damage to others’ property or completed work caused by faulty workmanship (subject to exclusions). Builders’ Risk covers resulting damage to the project from any cause, including faulty workmanship, but excludes the cost of fixing the defective work itself. Builders’ Risk continues to respond after work is complete but before project turnover, when CGL’s “your work” exclusions may bar coverage entirely.
| Coverage Feature | CGL Policy |
|---|---|
| Coverage Type | Third-party liability |
| What Triggers Coverage | Liability to others for damage or injury |
| Own Faulty Workmanship | EXCLUDED |
| Subcontractor Faulty Work | COVERED until work accepted |
| After Substantial Completion | Limited; completed operations with restrictions |
| Typical Deductibles | $0 to $25,000 |
| Coverage Feature | Builders’ Risk Policy |
|---|---|
| Coverage Type | First-party property |
| What Triggers Coverage | Direct physical loss to covered property |
| Own Faulty Workmanship | EXCLUDED, but resulting damage covered |
| Subcontractor Faulty Work | COVERED for resulting damage regardless |
| After Substantial Completion | Continues until project turnover or occupancy |
| Typical Deductibles | $50,000 to $500,000 for large projects |
Five Fatal Mistakes That Void Your Coverage
Even when policies include ensuing loss provisions or LEG 3 endorsements, specific mistakes can void coverage entirely. These errors occur frequently in construction project documentation and claims handling. They transform potentially covered losses into denied claims that contractors must self-fund.
Failing to Report Losses Promptly voids more claims than any other mistake. Builders’ Risk policies require notice “as soon as practicable” after discovering a loss. Some policies specify 24 to 72 hours. Contractors who delay reporting while investigating or attempting self-repair may forfeit coverage entirely. In Utility Systems of America v. Zurich American Insurance, the court held that a six-month delay in reporting constituted material breach of the notice requirement, barring recovery. Even legitimate claims get denied based on procedural violations.
Continuing Work That Aggravates the Loss violates the duty to protect property from further damage. Standard Builders’ Risk policies require insureds to protect property after a loss. Contractors who continue construction in affected areas, failing to properly secure or protect damaged work, may void coverage for additional damage. If a roof leak damages interior finishes but the contractor continues drywall installation in the affected area without tarping the roof, resulting damage to new drywall may be excluded. Insurers can reduce claim payments by the amount of avoidable additional damage or deny the entire claim for material breach.
Lack of Proper Documentation represents the most common reason covered claims get underpaid or denied. Contractors who fail to maintain detailed pre-loss condition photographs, installation specifications, and as-built drawings cannot prove the extent of resulting damage versus pre-existing defects. Without clear documentation showing what existed before the loss, insurers argue that claimed damage represents uncovered defective work rather than covered resulting loss. Burden of proof falls on the insured, who may lack evidence to establish coverage.
Inadequate Separation Between Defect and Damage dooms many otherwise valid claims. The ensuing loss exception requires physical separation between the defective work and resulting damage. Contractors claiming coverage for what appears to be a single integrated failure cannot satisfy this requirement. If a concrete slab cracks due to improper curing, insurers argue the cracked slab is the defective work itself, not resulting damage to separate property. Courts apply the “particular part” test, asking whether damage occurred to a discrete part of the property different from the part containing the defect.
Relying on Verbal Coverage Assurances creates false security that collapses when claims arise. Contractors who rely on insurance brokers’ verbal assurances about faulty workmanship coverage without reviewing actual policy language face denial. Brokers may misunderstand coverage nuances or overstate protection breadth. Only the written policy governs coverage, and courts consistently hold that insureds have a duty to read their policies. Contractors discover gaps only after sustaining losses.
Critical Do’s for Protecting Your Coverage
Purchase LEG 3 Coverage for Projects Over $50 Million. Projects exceeding this threshold should negotiate LEG 3 endorsements to eliminate coverage gaps for defects. While LEG 3 increases premiums by 25-40%, it provides comprehensive protection that prevents disputes over whether damage qualifies as resulting loss. The additional premium becomes insignificant compared to potential uncovered losses that could reach millions of dollars.
Maintain Daily Photographic Documentation. Implement systematic photo documentation protocols requiring site supervisors to photograph all work before it is concealed. Take daily progress shots from consistent vantage points and close-up images of critical connections and details. Use reality capture technology or 360-degree cameras to create comprehensive records. This documentation proves pre-loss conditions, establishes the scope of resulting damage, and supports coverage claims by clearly showing physical separation between defects and resulting losses.
Report All Potential Losses Within 24 Hours. Establish a reporting protocol requiring any loss exceeding $5,000 or involving potential defects be reported to insurers within 24 hours. Include preliminary assessments noting this is an initial report subject to revision. Early reporting preserves coverage, allows timely investigation, and prevents procedural denial. The claims process operates more smoothly when insurers are involved from the outset.
Coordinate Coverage Between CGL and Builders’ Risk. Work with insurance counsel to ensure CGL and Builders’ Risk policies coordinate without gaps or overlaps. Specify which policy provides primary coverage for different loss scenarios. Establish consistent deductibles where possible. Ensure both policies list all project stakeholders as insureds or additional insureds as appropriate.
Engage Qualified Quality Control Consultants. Hire independent quality control consultants to conduct regular inspections throughout construction. QC consultants document compliance with specifications and identify potential defects before they cause damage. QC consultant reports create contemporaneous records showing when defects arose, what work was performed correctly, and how resulting damage occurred. This documentation proves essential in claims where insurers dispute whether damage qualifies as resulting loss.
Critical Don’ts That Destroy Your Coverage
Don’t Assume All Defect-Related Damage Is Excluded. The most common misconception is that any loss involving defective work is automatically excluded. The ensuing loss provision restores coverage for resulting damage even when triggered by excluded defects. Contractors who fail to file claims because they assume exclusion applies lose valid coverage opportunities. Always submit claims for adjuster review.
Don’t Attempt DIY Repairs Before Filing Claims. Contractors who repair damage before documenting the loss and notifying insurers cannot prove what occurred or demonstrate coverage entitlement. Emergency stabilization to prevent further damage is required, but permanent repairs destroy evidence the adjuster needs to evaluate the claim. Photograph extensively, implement temporary protective measures, report to the insurer, and await inspection before proceeding with permanent repairs.
Don’t Mix Multiple Causes of Loss in Single Claims. When submitting claims involving both covered perils (fire, water, wind) and excluded perils (faulty workmanship), clearly separate and itemize costs attributable to each cause. Mixed claims where covered and uncovered damages are lumped together create disputes about proportionate allocation. Insurers may deny entire claims as predominantly defect-related when clear separation would have established significant covered loss.
Don’t Ignore Policy Definition of Resulting Damage. Each policy may define resulting or ensuing loss differently. Some require the resulting damage flow from a covered peril, while others merely require physical damage beyond the defect itself. Assuming all policies operate identically leads to incorrect claims handling. Review specific policy language and tailor claims strategy to your policy’s particular requirements.
Don’t Delay Obtaining LEG 3 Until After Project Start. Waiting until defects appear to seek broader coverage is impossible—policies cannot be modified retroactively to cover known losses. Negotiate LEG 3 endorsements during initial policy placement, before construction commences. Once work begins, insurers will not add coverage that could apply to work already performed.
Weighing the Pros and Cons of Different Coverage Options
| Coverage Option | Pros | Cons |
|---|---|---|
| Standard Builders’ Risk with Ensuing Loss | Affordable at 1-3% of project value; proven coverage; balanced protection; quick to bind | Ambiguity creates disputes in 25-30% of claims; contractor self-insures defect correction costs; partial coverage creates allocation disputes |
| LEG 3 Coverage | Broadest protection available; eliminates coverage disputes; prevents catastrophic losses; faster claim resolution | Premium increases 25-40%; higher deductibles ($100K-$500K); limited to proven contractors; some insurers refuse certain project types |
| Named Perils | Costs 40-60% less; adequate for simple projects; targeted protection | Insured bears burden of proof; extensive coverage gaps; unsuitable for complex projects; faulty workmanship via unnamed perils excluded entirely |
| Self-Insurance | Eliminates premium costs; direct control; incentivizes quality control | Single defect can bankrupt smaller contractors; lenders require policies; loses insurer expertise; contractors face full replacement costs |
How State Laws Change Construction Defect Claims
While Builders’ Risk policies generally follow similar formats nationwide, state laws create significant variations in how construction defect claims are handled. These differences impact when claims must be filed, what damages are recoverable, and how courts interpret coverage provisions.
California imposes complex limitation periods: four years for patent defects under Cal. Code Civ. Proc. § 337.1 and ten years for latent defects under § 337.15. California recognizes the discovery rule, meaning limitations begin when defects are discovered, not when work is completed. Claims can arise a decade after construction, requiring Builders’ Risk tail coverage or extended reporting periods. California also has extensive homeowner protections under the Right to Repair Act, requiring pre-litigation notice and opportunity to remedy defects.
Texas applies a four-year statute of limitations from when defects are discovered or should have been discovered through reasonable inspection. The state’s construction defect statute of repose is ten years from substantial completion, though recent Court of Appeals decisions have extended this in cases where defects remain concealed despite reasonable inspection. Texas also allows DTPA claims that can triple damages if violations are deemed knowing or intentional, creating enormous exposure.
Florida has a four-year statute of limitations for written contracts and a statute of repose varying from ten to fifteen years depending on the type of defect and structure. Florida courts have issued important decisions on ensuing loss provisions, including Swire Pacific Holdings v. Zurich, which established that design defect exclusions with exceptions cover damage flowing from defects but not the defects themselves. Florida also has specific legislation regarding condominium construction defects.
Colorado imposes a six-year statute of limitations and an eight-year statute of repose, both running from substantial completion. Colorado Construction Defect Action Reform Act (§§ 13-20-801 et seq.) mandates pre-litigation notice and inspection procedures, requiring claimants to provide at least 90 days’ notice before filing suit. This gives contractors opportunity to remedy defects before litigation, potentially reducing covered losses.
What Drives Your Builders’ Risk Premium Costs
Builders’ Risk insurance premiums typically range from 1% to 5% of total project value. Rates vary significantly based on multiple risk factors. Understanding these calculation factors allows contractors to manage costs and negotiate better terms.
Project Value and Scope serves as the primary rating factor. The calculation includes completed project value, covering all labor, materials, and soft costs. Larger projects ($10 million and up) often secure lower percentage rates at 1-2% due to economies of scale. Smaller projects ($500,000 or less) may pay 3-5% of project value. Insurers assess whether the project involves new construction (lower risk) or renovation (higher risk due to concealed conditions).
Location and Natural Hazards dramatically affect premiums. Coastal areas subject to hurricanes pay 50-150% surcharges for wind coverage. Earthquake zones require separate coverage or substantial additional premium. Urban areas with high theft rates pay more than rural locations. Flood zones may require separate NFIP coverage or private flood insurance at significant cost.
Construction Type determines base rates. Fire-resistant materials like concrete, steel, and masonry generate substantially lower rates than combustible construction. A concrete and steel office building might cost 1-2% of project value, while a wood-frame apartment project could cost 3-4% or more. Mixed construction types are rated at the highest risk category present.
Project Duration impacts premiums because exposure extends over time. A 12-month project pays approximately 1.0X the base rate, while a 24-month project might pay 1.5X and a 36-month project 2.0X or more. Duration surcharges reflect that more time allows more opportunities for losses.
Deductibles and Coverage Options significantly influence final costs. Increasing the deductible from $25,000 to $100,000 might reduce premium by 15-25%. Selecting a $500,000 deductible on a $50 million project could cut premium in half. Optional coverages add cost: LEG 3 provisions increase premium 25-40%, earthquake coverage adds 0.5-2% of project value, flood coverage varies based on zone but can exceed 1%, and soft costs coverage adds 10-20% to base premium.
Special Endorsements That Fill Coverage Gaps
Beyond LEG provisions, insurers offer specialized endorsements addressing specific faulty workmanship scenarios. These endorsements fill gaps in standard coverage. They provide tailored protection for unique project risks.
Faulty Workmanship Coverage Endorsement on CGL provides a separate faulty workmanship endorsement offering $10,000-$50,000 coverage for the cost to repair or replace faulty workmanship performed by the named insured. This fills the gap created by “your work” exclusions, covering scenarios like improperly installed flooring that must be removed and replaced. Premiums start at $30 minimum, scaling based on trade and revenues.
Testing of Newly Installed Equipment addresses a critical gap. Standard Builders’ Risk policies exclude damage occurring during testing and commissioning of mechanical, electrical, and plumbing systems. A specialized testing endorsement adds coverage for damage that occurs during startup, testing, and commissioning periods. This is critical for projects with complex HVAC, fire protection, or industrial process equipment where commissioning failures cause substantial damage. The endorsement typically includes a separate sublimit of $100,000-$500,000.
Collapse During Construction provides coverage for collapse caused by defective materials or construction methods. The ISO CP 11 20 endorsement restores this coverage, which standard Builders’ Risk policies exclude. Without this endorsement, structural collapse caused by faulty concrete, inadequate shoring, or defective structural components is excluded entirely—even though collapse represents one of the most catastrophic possible losses. Premium varies based on construction type and structural complexity but typically adds 0.1-0.5% of project value.
Soft Costs Coverage protects against consequential losses when faulty workmanship causes project delays. Soft costs accumulate rapidly: loan interest, real estate taxes, additional insurance premiums, and lost rental income. Standard Builders’ Risk excludes these consequential losses. A soft costs endorsement provides coverage for defined indirect costs during delay periods, typically with a monthly limit of $50,000-$500,000 per month and maximum duration of 12-24 months.
Mold and Fungi Limited Coverage addresses an increasingly common problem. While many Builders’ Risk policies exclude mold entirely, limited mold coverage endorsements provide sublimits of $10,000-$50,000 for mold remediation when mold results from a covered cause of loss. Given that water damage represents 30% of construction claims and frequently leads to mold if not immediately addressed, this endorsement provides essential protection.
Step-by-Step Guide to Filing Claims That Get Paid
When losses occur involving potential faulty workmanship, proper claims handling is critical. Following established procedures maximizes recovery while preserving coverage. Each step builds on the previous one.
Immediate Notification Within 24 Hours starts the clock. As soon as a loss is discovered or defect becomes apparent, notify the insurance broker and carrier in writing via email. Include preliminary information: date and time of discovery, general description of loss, estimated affected area or components, initial cause assessment (even if uncertain), and emergency measures implemented. State explicitly that this is preliminary notice subject to revision as investigation proceeds.
Emergency Mitigation Immediately prevents coverage forfeiture. Implement emergency measures to prevent additional damage: tarp roof openings, extract standing water, establish temporary environmental controls, secure damaged areas against theft or vandalism, and install shoring for structural instability. Document all mitigation efforts with photographs, detailed logs of actions taken, and costs incurred. The policy requires you to protect property from further damage—failure to mitigate creates basis for claim reduction or denial.
Comprehensive Documentation Within 48-72 Hours preserves evidence. Before disturbing the loss scene beyond emergency measures, create comprehensive documentation: extensive photographs from multiple angles of all damaged areas, close-up images of specific damage points, overall context shots showing damage location within project, video walkthroughs narrating what is visible, witness statements from workers who observed the loss, and preservation of physical evidence like failed components or samples. This documentation proves the scope of resulting damage separately from the underlying defect.
Formal Claim Submission Within 7 Days initiates the formal process. Submit formal written claim to the insurer including: completed claim form with all requested information, detailed narrative describing how the loss occurred, chronology of events from defect occurrence through discovery, itemized cost estimate for repairs (preliminary if full scope unknown), and reference to all relevant policy provisions. For losses involving faulty workmanship, clearly distinguish between defective work cost (excluded) and resulting damage cost (covered) in separate line items.
Adjuster Investigation and Evaluation requires your cooperation. The insurer will assign a construction adjuster who inspects the site, interviews witnesses, reviews project documentation, determines cause and origin, evaluates whether coverage applies, and assesses damage valuation. Provide all requested documentation, make personnel available for interviews, and allow full site access. Do not make binding admissions about causation or accept responsibility for defects.
Coverage Determination and Settlement Negotiation determines your recovery. After investigation, the insurer issues a coverage decision: acceptance, denial, or reservation of rights pending further investigation. If accepted, negotiate settlement including: agreement on repair scope and costs, determination of policy deductible application, consideration of betterment or depreciation if applicable, and coordination with other insurance if CGL also responds. If denied, request detailed written explanation citing specific policy provisions and factual basis.
Repairs and Final Accounting closes the claim. Once settlement is agreed, proceed with repairs maintaining detailed cost records, change order documentation, photographic progress records, and final completion documentation. Submit final claim accounting including actual costs incurred, supporting invoices and receipts, comparison to initial estimate with explanation of differences, and request for final payment. Most policies require repair completion before final payment, though advances for material and labor costs may be available.
Why Construction Defect Claims Are Surging Nationwide
Construction defect claims are surging across the United States, driven by multiple converging factors. Understanding these trends allows better risk management. Insurance planning becomes more strategic.
Labor Shortages Creating Quality Issues drives defect frequency upward. The construction industry faces severe shortages of skilled labor, with experienced tradespeople retiring faster than new workers enter the field. This forces contractors to use less experienced workers, increasing the likelihood of errors, substandard workmanship, and oversights that later become defect claims. Recent surveys indicate the shortage is most acute in specialized trades like electrical, plumbing, and HVAC installation—precisely the trades where defects cause the most significant damage.
Post-Disaster Rebuilding Pressure creates perfect conditions for defects. Natural disasters like hurricanes, wildfires, and floods create urgent rebuilding demand that strains construction resources. Contractors working under compressed timelines in disaster zones face pressure to complete projects quickly, sometimes leading to loosened permit requirements or waived inspections. Insurance companies report elevated claim frequency in regions rebuilding after disasters, with claims emerging 2-5 years post-construction as defects manifest.
High-End Custom Projects generate disproportionate claims. Luxury residential construction—homes valued at $10-15 million or more—is experiencing a surge in defect claims. These projects involve complex custom designs, innovative construction techniques, and high owner expectations. When sophisticated clients discover defects, they retain specialized counsel and pursue aggressive litigation. Average claim values in this segment exceed $2-5 million, with some reaching $10 million or more.
Infrastructure Investment Boom creates future claim exposure. The $1.2 trillion Infrastructure Investment Act is generating enormous public works construction, particularly in states like Texas, Florida, and California. As these projects near completion, municipalities are filing claims alleging defects. Public entity claims carry heightened scrutiny and political pressure, often resulting in protracted litigation.
Nuclear Verdicts and Social Inflation amplify damages. Construction defect litigation is affected by the broader trend of nuclear verdicts—jury awards exceeding $10 million. When juries perceive injustice, particularly homeowners harmed by defective construction, they award substantial damages including punitive amounts. Average commercial construction defect claims in Texas now approach $10.1 million, up from $6-7 million five years ago.
Increased Insurance Denials creates friction between insurers and insureds. Despite rising premiums, insurers are denying construction claims at higher rates, citing faulty workmanship exclusions, late reporting, and inadequate documentation. In 2024, commercial construction insurance premiums increased 10.1% while claim denial rates rose 15-20%. This creates a challenging environment where contractors pay more for coverage that may not respond when needed.
How to Read Your Policy for Faulty Workmanship Coverage
Builders’ Risk policies are not standardized—coverage varies significantly based on form, endorsements, and manuscript language. Knowing how to analyze your specific policy prevents unpleasant surprises. Claims arise when you least expect them.
Locate the Insuring Agreement defines what is covered. Look for language stating the insurer will pay for “direct physical loss of or damage to Covered Property at the premises…caused by or resulting from any Covered Cause of Loss.” Note whether the policy is all-risk (covering all causes except those excluded) or named perils (covering only specified causes). All-risk policies provide broader protection for faulty workmanship resulting damage.
Review Exclusions Carefully reveals what insurers won’t pay. Find the exclusions section and locate provisions addressing defects, faulty workmanship, design errors, and materials defects. Common language states: “We will not pay for loss or damage caused by or resulting from: Faulty, inadequate or defective design, specifications, workmanship, repair, construction, materials used in construction.” Note the specific wording—”caused by” is narrower than “caused by or resulting from.”
Identify Ensuing Loss Language restores critical coverage. Immediately after the faulty workmanship exclusion, look for exception or proviso language. This typically reads: “But if loss or damage by a Covered Cause of Loss results, we will cover that resulting loss or damage” or “unless physical damage not otherwise excluded by this policy results, in which event this policy shall insure such resulting damage.” This critical provision restores coverage for resulting losses—even when triggered by excluded faulty workmanship.
Check for LEG Endorsements significantly changes coverage breadth. Review the policy’s endorsement schedule for references to LEG 1, LEG 2, or LEG 3 provisions. These may be listed as “London Engineering Group Defects Exclusion Clause” or similar language. If present, obtain the full endorsement text because LEG provisions substantially modify standard exclusions.
Examine Definitions controls interpretation. Review the definitions section for terms like “Occurrence,” “Physical Loss or Damage,” “Your Work,” “Covered Property,” and “Resulting Damage.” How these terms are defined determines coverage application. If the policy defines “Physical Loss or Damage” to include deterioration or defect, coverage is broader than if it requires sudden and accidental events.
Assess Additional Coverages and Extensions adds value. Look for sections titled “Additional Coverages,” “Coverage Extensions,” or “Supplemental Coverages.” These may provide limited coverage for testing of equipment, debris removal, pollution cleanup, collapse during construction, or soft costs. Note any sublimits, special deductibles, or additional requirements for these coverages.
Understand Conditions and Duties After Loss prevents procedural denials. Review the “Conditions” section specifying duties after loss occurs. Note exact timeframes for reporting, requirements to protect property from further damage, cooperation obligations, and documentation requirements. Failure to satisfy these conditions can void coverage for otherwise valid claims.
When to Hire Insurance Coverage Counsel
Construction insurance disputes involve complex interactions between policy language, construction contracts, case law, and technical construction issues. Knowing when to engage specialized counsel prevents mistakes. Coverage rights can be forfeited through procedural errors.
Before Policy Purchase prevents expensive gaps. Consult counsel when selecting coverage for projects exceeding $10 million, negotiating manuscript policy forms, evaluating whether to purchase LEG 3 coverage, or determining adequate limits and deductibles. Coverage counsel reviews proposed policies, identifies gaps, negotiates broader terms, and ensures coordination between multiple policies. This investment—typically $5,000-$15,000—prevents far larger uncovered losses.
After Major Losses protects your rights. Engage counsel immediately when losses exceed $500,000, claims involve both covered and excluded perils, insurers issue reservation of rights letters, multiple policies may respond, or coverage disputes are anticipated. Counsel protects your rights by reviewing claim submissions before filing, advising on investigation cooperation while preserving privileges, analyzing coverage under all potentially applicable policies, and negotiating with insurers from a position of knowledge.
During Coverage Disputes requires professional representation. If insurers deny claims, offer inadequate settlements, or raise exclusion defenses, coverage counsel becomes essential. Counsel analyzes policy language, researches applicable case law (which varies significantly by state), evaluates the strength of positions, negotiates from informed positions, and pursues litigation or arbitration if necessary. Given that construction defect claims often involve $1-10 million in damages, legal fees of $50,000-$200,000 for coverage litigation represent sound investment.
Frequently Asked Questions
Does Builders’ Risk cover poor workmanship?
No. Builders’ Risk excludes costs to repair or replace poor workmanship itself. Coverage applies to resulting damage that poor workmanship causes to other project components.
What is the difference between CGL and Builders’ Risk coverage?
Different focus. CGL provides third-party liability protection for damage your work causes to others. Builders’ Risk provides first-party property protection for direct physical loss to the project.
Can I add LEG 3 coverage after construction starts?
No. LEG 3 endorsements must be added at policy inception before construction commences. Insurers will not add broader coverage retroactively to protect work already performed.
How long does Builders’ Risk coverage last?
Until completion. Coverage terminates when construction completes, the building is occupied, the policy expiration date arrives, or the insured’s interest ceases—whichever occurs first.
Does Builders’ Risk cover design defects?
Resulting damage only. The cost to correct design defects is excluded. If a design defect causes damage to constructed work, that resulting damage may be covered.
What is an ensuing loss provision?
Coverage restoration. Ensuing loss language restores coverage for damage flowing from excluded causes. When faulty workmanship triggers a covered peril, the ensuing loss provision covers resulting damage.
Do I need to report all defects to my insurer?
Report potential losses. Report any defect that causes or may cause physical damage exceeding the deductible. Defects causing resulting damage require prompt notice to preserve coverage rights.
Will my premium increase if I file a claim?
Likely yes. Claims history significantly impacts future insurability and premiums. However, failing to file valid claims wastes purchased coverage that you already paid for.
What deductible should I choose for my project?
Balance cost and risk. For projects under $5 million, $25,000-$50,000 deductibles balance cost and protection. Projects over $10 million often use $100,000-$500,000 deductibles.
Can subcontractors file claims under my Builders’ Risk policy?
If named as insureds. Subcontractors must be listed as named insureds or additional insureds to file claims. Most policies can include all contractors and subcontractors.
Does water damage from faulty plumbing count as faulty workmanship?
Partial coverage. The cost to repair the faulty plumbing is excluded. Water damage to drywall, flooring, and other components is covered as resulting damage.
What happens if I continue working after discovering a loss?
Coverage may be voided. Policies require you protect property from further damage. Continuing work in affected areas without emergency stabilization or insurer approval may void coverage.
Should I purchase all-risk or named perils coverage?
All-risk is better. Unless project risk profile is extremely simple, all-risk coverage provides superior protection including ensuing loss provisions for faulty workmanship resulting damage.
How do I prove resulting damage is separate from the defect?
Documentation is critical. Use photographs, expert reports, and detailed damage assessments showing physical separation between defective work and resulting damage to separate property components.
Can I get coverage for correcting code violations?
Generally no. Code violations represent business risks rather than insurable perils. However, building ordinance coverage endorsements may cover costs to repair damaged work to current code.
What is a reservation of rights letter?
Conditional investigation. Insurers issue reservation letters stating they will investigate the claim but reserve the right to deny coverage based on exclusions or conditions.
Does Builders’ Risk cover theft of materials?
Usually yes. Most policies cover theft, though some exclude theft of materials not yet incorporated or theft occurring when no watchperson is present.
Can the owner and contractor have separate Builders’ Risk policies?
Not recommended. Dual policies create coordination problems, coverage gaps, and disputes. Best practice is a single policy covering all parties with insurable interests.
What is the difference between LEG 2 and LEG 3?
Breadth of coverage. LEG 2 excludes costs that would have been incurred to fix defects before damage occurred. LEG 3 covers all defect costs except improvements.
Do I need separate earthquake or flood coverage?
Usually yes. Standard Builders’ Risk excludes earthquake and flood unless specifically added by endorsement or separate policy. Projects in seismic zones or flood areas require additions.
