To make a claim against a contractor’s insurance, you file as a third party against the contractor’s policy: identify the insurer and policy number, document your damage in detail, send written notice of loss, and work through the assigned adjuster toward a settlement. If the insurer denies the claim or offers too little, the next steps are a formal demand letter, mediation or arbitration, and, if necessary, a lawsuit before your state’s filing deadline runs out.
The process runs differently from filing on your own homeowner’s policy. You are the claimant, not the policyholder, and the insurer’s primary duty runs to the contractor. That shapes almost everything about how the claim moves.
Figure Out Which Policy Actually Applies
Contractors typically carry more than one type of insurance, and only some of them respond to a homeowner’s claim.
General liability is the policy most claims run through. It covers bodily injury and property damage caused by the contractor’s work, such as a crew member breaking a water line or a falling ladder damaging a fence.
Professional liability, sometimes called errors and omissions coverage, is separate. It applies when a contractor’s design advice, engineering recommendations, or professional judgment causes a financial loss. Faulty design leading to structural problems is the classic professional liability claim.
Workers’ compensation is the third policy you’ll hear about, but it doesn’t help you. It covers the contractor’s employees if they’re injured on your property. It does not pay for damage to your property or losses from poor workmanship.
One coverage limit worth knowing before you file: general liability policies usually don’t pay to redo the contractor’s own defective work. If a roofer installs shingles incorrectly, the cost to redo the shingles is generally excluded. But water damage to your interior from the faulty roof often is covered, because that’s consequential property damage rather than the workmanship itself. Some policies also exclude pollution, certain mold damage, and intentional acts. Ask the insurer about exclusions early so you know what’s in play.
Every liability policy also has a payout cap. Common general liability limits are $1 million per occurrence and $2 million aggregate, though smaller contractors sometimes carry less. If your damages exceed the limit, the contractor is personally responsible for the difference.
Get the Contractor’s Insurance Information
You can’t file until you know who to file with. The simplest approach is asking the contractor directly for a copy of their certificate of insurance, which lists both the insurer and the policy number. If you signed a construction contract, check it first — many contracts require the contractor to furnish proof of insurance up front.
When the contractor won’t respond or refuses to hand over their insurance details, your state’s contractor licensing board is the next stop. Most states that license contractors also require proof of insurance as a condition of that license, and licensing records are public. A search using the contractor’s license number often surfaces the insurer and policy number. Your own homeowner’s insurance company may also be able to help identify the contractor’s coverage through industry databases.
Document the Damage Before You Do Anything Else
Documentation is where most claims are won or lost. The adjuster will scrutinize every detail, and gaps in your evidence become reasons to reduce or deny the payout. Start collecting evidence as soon as you discover the problem.
- High-resolution photographs and video from multiple angles, wide shots for context and close-ups for detail. Timestamp everything, and re-photograph if the damage worsens over time.
- The original contract, any change orders, and written specifications. These establish what the contractor agreed to do and the standards that applied.
- Every email, text message, voicemail, and letter between you and the contractor. Communication records build the timeline and show whether the contractor acknowledged or refused to fix the problem.
- At least one repair estimate from a licensed contractor with no relationship to the original one. An independent estimate carries far more weight than your own guess at repair costs, and it holds up if the claim turns adversarial.
- Receipts for any emergency repairs, temporary housing, or other out-of-pocket costs caused by the damage.
Organize the whole file chronologically. When the adjuster reviews the claim, a clear timeline with supporting documents makes your case easier to evaluate and harder to contest.
File the Third-Party Claim
Send Written Notice to the Insurer
Contact the contractor’s insurance company as soon as possible after the damage occurs or is discovered. Contractor policies typically require the insured to report claims “as soon as practicable” or within a specific number of days. As a third-party claimant you aren’t bound by those exact deadlines, but delays hurt your credibility and give the insurer grounds to complicate the process.
Written notice should include your name and contact information, the contractor’s name and policy number, a description of the incident, the date it occurred or was discovered, and a summary of the damages with your estimated repair cost.
Work With the Assigned Adjuster
The insurer will assign a claims adjuster to investigate. The adjuster works for the insurance company, not for you. Cooperate, but be careful. The adjuster will likely want to inspect the damage in person, review your documentation, and interview both you and the contractor.
Provide everything requested, but don’t speculate about causes or agree to characterizations of the damage you aren’t sure about. Stick to facts you can document. The adjuster will often obtain their own repair estimates, and if those come in significantly below yours, your independent estimate becomes the leverage that anchors the negotiation.
Send a Demand Letter
Once the investigation wraps up, a formal demand letter sharpens the negotiation. Lay out the facts of the incident, describe your damages with supporting documentation, itemize your financial losses, and state the specific dollar amount you’re seeking. Keep the tone factual and professional. A demand letter signals you’re serious about the full value of the claim and creates a paper trail that matters if the case escalates.
If the Insurer Denies the Claim
A denial isn’t the end of the road. Insurers must explain the reason for denial in writing, so get the denial letter and read it closely.
Common reasons include damage falling outside coverage, a lapsed policy, failure to give timely notice, or the insurer’s conclusion that the contractor wasn’t at fault. Each has a different path forward. If the denial rests on a coverage interpretation you disagree with, you can request a review and submit additional documentation. If the insurer argues the contractor wasn’t liable, expert opinions or inspection reports can support your position.
Insurers have a legal duty to investigate claims in good faith. If a denial looks unreasonable or the investigation was inadequate, that’s the point where legal counsel earns its cost. An attorney who handles insurance disputes can evaluate whether the denial was proper and whether a bad faith claim against the insurer is warranted.
Claims Against a Surety Bond
Some contractors carry surety bonds instead of, or in addition to, liability insurance. A bond is not insurance in the traditional sense. It’s a three-party agreement between the contractor (the principal), the entity requiring the bond (the obligee, often a state licensing board or project owner), and the surety company that guarantees the contractor’s obligations. If the contractor fails to perform or pay subcontractors, the surety compensates the injured party and then seeks reimbursement from the contractor.
State-mandated contractor licensing bonds typically range from $5,000 to $50,000, so bond claims are better suited for smaller disputes. To file, write to the surety company, explain the claim, and submit documentation: contracts, invoices, proof of payment, and correspondence with the contractor. The surety will contact the contractor for their side before deciding. Courts enforce notice deadlines on bond claims strictly, so check the bond’s terms and any applicable state statutes for filing windows.
One key difference from insurance: after a surety pays, the contractor owes that money back to the surety. That gives contractors a strong incentive to resolve bond claims quickly, because dragging it out only creates personal liability.
Settlement, Mediation, Arbitration, and Small Claims
Most claims that aren’t denied outright move into settlement negotiations. The insurer’s first offer is almost always lower than what you asked for. That’s expected. Compare their offer against your independent estimate and documented losses. If the gap is small, brief negotiation often closes it. If the gap is large, plan for a longer process.
When direct negotiation stalls, many contractor insurance policies require alternative dispute resolution before you can sue. Mediation uses a neutral third party to help both sides reach a voluntary agreement; it’s non-binding, and either side can walk away. Arbitration is different: an arbitrator hears both sides and issues a decision that’s usually binding. Some contractor policies include mandatory arbitration clauses that block court entirely, so check the policy language early.
If your damages fall below your state’s small claims court threshold, which ranges from about $2,500 to $25,000 depending on the jurisdiction, small claims court is a faster and cheaper alternative to formal litigation. No attorney required, low filing fees, and cases are typically heard within a few months.
Watch the Statute of Limitations
Every state sets a deadline for filing a lawsuit over property damage or breach of contract. Miss it and you lose the right to sue, however strong the claim. For property damage caused by contractor work, the window is typically two to six years depending on the state, though some allow longer. Breach of contract claims often have separate and sometimes longer deadlines.
The clock usually starts on the date the damage occurred. But some damage isn’t immediately visible. Faulty plumbing behind a wall might not surface for months or years. Most states apply a “discovery rule” that starts the clock when you knew or reasonably should have known about the damage. Some states also impose a separate “statute of repose” — an absolute outer deadline measured from the date of project completion, regardless of when the damage was discovered.
Don’t confuse the statute of limitations with the insurance policy’s notification period. The notification period is the window for reporting the claim to the insurer, and it’s almost always shorter than the lawsuit deadline. Both matter.
Bringing in a Public Adjuster or Attorney
A public adjuster is a licensed professional who works only for you, not the insurer. Public adjusters handle damage inspection, documentation, repair cost calculations, and negotiation. They earn their fee on complex property damage where the scope of loss is hard to quantify or where the insurer’s adjuster has significantly undervalued the damage. Fees typically run 10% to 15% of the settlement, though state caps vary widely. Some states cap fees at 10%, others allow up to 20%, and several states reduce the allowable fee during declared emergencies. On a straightforward, well-documented claim you probably don’t need one; on a large contested claim, a good public adjuster often recovers more than enough additional money to cover the fee.
Not every claim needs a lawyer either. For straightforward damage where the insurer is responsive and the numbers are reasonable, you can handle it yourself. Hiring an attorney makes sense when the dollar amounts are significant, when the insurer denies the claim or acts in bad faith, when the contractor disputes liability, or when a statute of limitations deadline is approaching without progress. Look for someone who handles insurance disputes or construction litigation specifically. Many offer free initial consultations and take larger claims on contingency, meaning they’re paid from the settlement rather than billing hourly.
Present Your Damages Honestly
Exaggerating damages, fabricating evidence, or misrepresenting facts to an insurer is insurance fraud, and the penalties are serious — from state fines and criminal charges to being blacklisted by insurers in the future. Document the actual losses thoroughly and present them accurately. If you aren’t sure whether something qualifies as a covered loss, ask the adjuster or an attorney rather than guessing and risking an overstated claim.
