Why You Should Ask Contractors for Proof of Insurance

A burst pipe during a kitchen remodel. A roofer who falls from a ladder. A subcontractor's backhoe that clips your gas line. These aren't hypothetical disasters: they're real claims that homeowners face every year, and the financial fallout depends almost entirely on one question you asked before the work started. Did you ask your contractor to provide proof of insurance before hiring them? If the answer is no, you could be personally responsible for medical bills, property repairs, and legal costs that run into six figures. The good news is that protecting yourself takes just a few minutes of due diligence. This guide walks you through the specific risks of hiring uninsured contractors, the types of coverage you should look for, how to verify that a policy is actually active, and what steps to take before any project begins. Whether you're planning a simple deck addition or a full home renovation, understanding these basics can save you from a financial nightmare. With construction spending in the U.S. now exceeding $2 trillion annually, more homeowners than ever are hiring contractors, and more of them are learning the hard way that a handshake isn't enough. Here's what you need to know.

The Real Risks of Hiring Uninsured Contractors

Hiring a contractor without insurance might save a few hundred dollars on the bid, but the exposure you take on is wildly disproportionate. An uninsured contractor shifts every financial risk directly onto your shoulders. That includes injuries, property damage, and lawsuits, all of which can blow past the cost of the project itself within days.

The risks of hiring an uninsured contractor are well documented, yet many homeowners skip this step because they assume their own homeowner's policy will cover any mishaps. That assumption is dangerous, and often wrong.

Your Liability for On-Site Injuries

If a contractor or their worker is injured on your property and they don't carry workers' compensation insurance, you may be held liable for their medical expenses. In many states, the property owner is considered the "statutory employer" when the hired party lacks coverage. That means the injured worker can file a claim directly against you.

Your homeowner's insurance might cover some medical payments to others, but these limits are often capped at $1,000 to $5,000 per person. A serious fall or power tool injury can generate $50,000 to $200,000 in medical bills. The gap between what your policy covers and what you owe comes straight out of your pocket. Homeowners are often liable when an uninsured contractor gets hurt on their property, regardless of who was at fault.

Property Damage and Repair Costs

Contractors work with heavy equipment, open flames, chemicals, and power tools. Mistakes happen. A plumber might flood your basement. An electrician could cause a fire behind the drywall. Without the contractor's own general liability policy, you're left filing a claim on your homeowner's insurance, which raises your premiums and may not even cover the full repair.

I've seen cases where a contractor's demolition work cracked a neighbor's foundation wall. The homeowner's policy excluded damage caused by hired workers, and the contractor had no insurance. The homeowner ended up paying $38,000 out of pocket for the neighbor's structural repairs.

Legal Fees and Lawsuit Exposure

Even if you believe you're not at fault, lawsuits are expensive to defend. Attorney fees in construction-related litigation typically run $250 to $500 per hour, and cases can drag on for months. If an injured worker or damaged neighbor sues you, the legal costs alone can exceed $20,000 before you ever reach a courtroom. An insured contractor's policy absorbs these costs. Without it, you're the one writing the checks.

Understanding the Types of Coverage Needed

Not all insurance policies are created equal, and a contractor who carries one type of coverage may still leave you exposed in other areas. Before you hire anyone, you should understand the three main categories of contractor insurance and what each one protects.

General Liability vs. Workers' Compensation

General liability insurance covers third-party bodily injury and property damage. If a contractor's work damages your home or injures a visitor, this policy responds. Workers' compensation, on the other hand, covers the contractor's own employees when they get hurt on the job. Both are critical, but they protect different people.

A solo contractor with no employees might not be required to carry workers' comp in your state, but that doesn't mean you're off the hook. If they're injured, they can still sue you as the property owner. Some states, like California and New York, have strict rules about this. New York contractors in particular are facing an insurance cost crisis in 2026 that's pushing some to drop coverage entirely, making verification even more important.

Professional Liability for Design Errors

If your project involves architectural plans, engineering, or design work, professional liability insurance (sometimes called errors and omissions) covers mistakes in the professional services themselves. A general liability policy won't cover a structural engineer's miscalculation that leads to a sagging floor. Professional liability fills that gap.

This coverage matters most for design-build firms, architects, and specialty contractors who both design and install systems. If your contractor is handling HVAC design, structural modifications, or custom fabrication, ask specifically about professional liability.

Comparison: Essential Contractor Insurance Policies

This table isn't exhaustive, but it covers the policies you're most likely to encounter. A reputable contractor doing residential work should carry, at minimum, general liability and workers' compensation. The 2026 insurance outlook for construction shows premiums rising across most lines, which means some contractors may be tempted to let policies lapse. Don't assume last year's certificate is still valid.

How to Verify a Certificate of Insurance (COI)

A Certificate of Insurance is a one-page document that summarizes a contractor's active policies, coverage limits, and expiration dates. It's the standard proof of insurance in the construction industry, and any legitimate contractor should be able to produce one within 24 hours. But having a COI in hand isn't enough. You need to verify it.

Checking Policy Expiration Dates

The first thing to look at is the policy period. Every COI lists a start date and an expiration date for each policy. If the expiration date is within 30 days of your project's start, ask the contractor for a renewal confirmation. Policies that expire mid-project leave you unprotected from that point forward.

Here's a detail most homeowners miss: roughly 15% of small vendor insurance policies are cancelled mid-term, and only 20% of carriers reliably notify the hiring party. That means a contractor's insurance could be cancelled a week after they hand you the certificate, and you'd never know. This certificate tracking gap is one of the biggest blind spots in contractor risk management.

Contacting the Insurance Agency Directly

Don't just read the COI: call the insurance agency listed on it. Ask them to confirm that the policy is active, that the named insured matches your contractor, and that the coverage limits match what's printed on the certificate. This takes five minutes and eliminates the risk of forged or outdated documents.

You can also request to be added as an "additional insured" on the contractor's general liability policy. This gives you direct protection under their policy if a claim arises from their work. Most carriers will add this endorsement at no extra charge. If a contractor resists this request, that's a red flag.

Questions Most Homeowners Ask About Insurance

Do I really need to ask for proof of insurance for a small job? Yes. Even a $2,000 bathroom tile job can result in a water damage claim that costs $15,000 to fix. The size of the project doesn't reduce your liability.

What if the contractor says they're bonded? Is that the same as insured? No. A surety bond protects you if the contractor fails to complete the work or violates the contract. It doesn't cover injuries or property damage. You need both bonding and insurance.

Can my homeowner's insurance cover contractor injuries? Your policy's medical payments coverage is limited, typically $1,000 to $5,000. Most homeowner's policies don't fully cover injuries to contractors working on your property. That's why the contractor's own workers' comp matters.

What if the contractor works alone and has no employees? Even solo contractors should carry general liability. In some states, they're also required to carry workers' comp for themselves. Check your state's requirements, because if they're injured and uninsured, you could still face a lawsuit.

Are there new laws in 2026 that affect contractor insurance? Yes. Several states have introduced new contractor insurance requirements for 2026, including stricter licensing standards and mandatory minimum coverage thresholds. Check your state's contractor licensing board for current rules.

Should I ask subcontractors for proof of insurance too? If your general contractor hires subcontractors, ask your GC to confirm that every sub carries their own coverage. If a subcontractor is uninsured and gets hurt, the liability chain can reach all the way back to you.

Protecting Your Assets Before the Project Starts

The time to verify insurance is before any work begins, not after a pipe bursts or someone falls off a scaffold. Make it a non-negotiable step in your hiring process, right alongside checking references and reviewing the contract.

Start by requesting a current COI from every contractor you're considering. Call the insurance agency to confirm the policy is active. Ask to be added as an additional insured on their general liability policy. And include a clause in your written contract that requires the contractor to maintain insurance throughout the duration of the project.

These steps take less than an hour combined, and they can save you tens of thousands of dollars. The contractors who push back on insurance requests are often the ones you should avoid. Professionals expect this question and are happy to provide documentation. Your home is likely your largest financial asset. Protecting it starts with a simple request for proof of coverage before any tools come out of the truck.
