Contractor Construction Defect Defense: Protecting Yourself From Claims

The letter arrives on a Tuesday: a building you worked on five years ago is the subject of a construction defect claim, and your company is named. You do not know yet whether the defect is your work, whether your insurance responds, or what you are supposed to do first. What you do know is that construction defect claims like this can threaten the company. This article is written for that moment, and for the contractor who wants to be ready before it arrives.

Nearly all defect content is written for the owner or HOA pursuing the claim. Contractors are treated as the faceless defendant. But contractors have defenses, coverage rights, and recovery options of their own, and knowing them is the difference between a managed claim and an existential one.

The Three Situations Contractors Face

You are named in a claim or suit for defects in work you performed, supervised, or subcontracted years ago.
Your carrier denies coverage on a defect claim you assumed your liability policy would handle.
Nothing has happened yet, and you want the documentation, contracts, and coverage in place so the first two situations stay manageable.

The advice differs by situation, so identify yours first. Defense of an active claim is triage; prevention is structure. Both are below.

The First 48 Hours After Notice

The opening moves set the tone for the entire claim, and the mirror-image urgency applies on the claimant side too, as owners are told in the first 48 hours of a defect emergency. For the contractor receiving notice:

Read the notice carefully. Identify exactly what defect is alleged, at what property, and by whom. Vague panic loses claims; precise understanding manages them.
Notify your carrier immediately. Liability policies carry strict notice requirements, and late notice is one of the most avoidable ways to jeopardize coverage. Do not wait to see whether it goes away.
Preserve everything. Contracts, subcontracts, change orders, inspection reports, as-builts, photos, correspondence. Contemporaneous documentation is your primary defense asset.
Route all communication through your carrier and counsel. Do not respond directly to the owner, HOA, or their representatives. Well-intentioned direct communication creates admissions and complications that professionals then have to unwind.

How Contractor Liability Is Actually Determined

Being named is not the same as being liable. The liability analysis turns on scope: was the alleged defect work you performed, work you supervised, or work another party performed entirely? Your contract documents and the project’s as-built record answer that question, which is why preserved documentation matters more than anything said in the demand letter. Claims frequently name every contractor on the project reflexively; the ones with clean scope documentation and clear subcontract allocations exit early or cheaply. The ones without become the deep pocket by default.

Contractors facing defect claims often assume they cannot defend against them. In reality, defense depends on specifics: what was the defect, who was responsible for quality, what does your insurance cover. AMPR’s professional assessment of your exposure can mean the difference between significant liability and a covered claim.

What Your Insurance Actually Covers, and Where It Fights You

Most contractors discover what their commercial general liability policy really covers at the worst possible time. CGL policies respond to property damage, but defect claims sit in contested territory: many policies exclude damage to your own work, carve out particular risks through targeted exclusions, and dispute whether a defect constitutes a covered occurrence at all.

Completed-operations coverage, the coverage that responds to claims arising after the work is done, is exactly where defect claims live, and its limits and exclusions deserve a careful read before you ever need them. The common traps are mapped in construction defect coverage gaps, and for projects insured under wrap-up programs, in wrap-up insurance coverage gaps.

If your carrier denies, do not treat the denial as a verdict. Denials rest on the carrier’s interpretation of policy language, and many are challengeable: through coverage counsel where language is ambiguous, through the state insurance regulator, or through negotiated partial coverage. The playbook for contesting a denial is laid out in how to fight a denied construction defect claim. Persistence, applied through the right channels, reverses more denials than contractors expect.

The Statute of Repose: Your Calendar Defense

Every state sets an outside deadline after which construction claims are barred regardless of when the defect was discovered. In California, the statute of repose for latent defects is ten years from substantial completion, with a much shorter four-year limit for patent defects; other states range from roughly six to twelve years, with varying triggers and exceptions. Know your completion dates and your state’s rule, because the calendar can be a complete defense. If the alleged work falls outside the repose window, that is often the first and cheapest argument to make. The claimant-side view of these deadlines is covered in construction defect statutes of limitation; contractors should read it in reverse.

The Subcontractor Recovery Option

If you are the general contractor and a subcontractor’s work caused the defect, defense is only half your position; recovery is the other half. With three elements in place, the claim against you can substantially become a claim against your sub: documentation that the sub performed the specific work, evidence the work was defective, and subcontract indemnity language allocating that liability. This is why subcontract terms deserve attention before any claim exists. Review your indemnity, additional-insured, and defense provisions now, while they are just paperwork, not after they have become the difference between a covered pass-through and an uninsured loss.

Protection Before the Letter Arrives

Prevention is unglamorous and decisive: photograph work in progress, obtain inspections at key stages, document subcontractor completion, preserve change orders and as-builts, and keep them organized for at least the length of your state’s repose period. Confirm your CGL and completed-operations limits fit the size of the projects you actually build. Make sure subcontracts allocate defect liability deliberately rather than by template default. The contractors who survive defect claims cheaply are almost never the lucky ones; they are the documented ones. AMPR’s contractor-side services cover both the pre-claim structure and the active-claim response.

Frequently Asked Questions

I just got a letter saying a building I worked on is being sued for defects. What do I do in the first 48 hours?

First, read the letter carefully and identify what defect is claimed and by whom. Second, notify your insurance carrier immediately; late notice can jeopardize coverage. Third, preserve all documentation of the work: contracts, change orders, inspection reports, drawings, photos. Fourth, do not communicate directly with the owner, HOA, or claimant; everything routes through your carrier and counsel. Those 48 hours set the tone for the entire claim.

My carrier denied coverage. Can they really do that?

They can assert it, but many denials are wrong or challengeable. If the denial rests on ambiguous policy language, coverage counsel can dispute it; you can also file a complaint with the state insurance regulator or negotiate partial coverage. Many denials are reversed when informed pressure is applied through the right channels. Do not accept a coverage denial at face value.

How long after completing work can someone sue me for construction defects?

The statute of repose sets the outside deadline and varies by state. California allows ten years from substantial completion for latent defects and four years for patent defects; other states commonly range from six to twelve years with different triggers and exceptions. Know your state’s rule and your completion dates. Past the window, you have a strong calendar defense; inside it, you manage the claim.

If a subcontractor caused the defect, am I liable as the GC?

It depends on your subcontract and the specifics. In some structures the GC bears liability for subs’ work; in others the sub is liable and owes you indemnity. Contract language decides. Review your subcontracts now, before a claim, to understand who bears what. If a sub’s defective work triggers a claim against you, well-drafted indemnity language gives you a recovery path against them.

What should I have been doing all along to protect myself?

Documentation first: photograph work in progress, obtain staged inspections, record subcontractor completion dates, preserve change orders and as-builts. That contemporaneous record is your proof, years later, that the work was done right. Second, make sure contracts allocate defect liability deliberately among GC, subs, and owner. Third, maintain liability and completed-operations limits sized to the projects you actually build.

Can I recover from a subcontractor whose defective work caused the claim against me?

Often yes, if three elements line up: documentation that the sub performed the specific work, proof the work was defective, and subcontract indemnity language allocating liability. With all three, the claim against you can become substantially the sub’s problem, including defense costs. Without them, you absorb it. This is the strongest argument for tightening subcontract terms before you need them.
