Why Verifying Contractor Insurance Protects Your Home
A contractor's insurance pays when a worker gets hurt on your property or a crew damages your home. This guide from M Property Services shows how to verify insurance for home contractors.
A piece of paper saying "insured" proves nothing.
Contractor insurance verification means confirming active general liability and workers' compensation coverage before work begins.
Every year, homeowners pay out of pocket for injuries and damage a policy should have covered. The fix takes ten minutes.
Below: how to check a license, read a certificate of insurance, and spot the gaps that leave homeowners exposed.
How to Check If a Contractor Is Licensed and Insured
Start with the license, then insurance. A license confirms the contractor met state requirements; insurance confirms there's money behind the work if something goes wrong.
You need both. One without the other leaves a hole.
Ask for the license number and insurance certificate together. A professional hands both over without hesitation.
Using Your State Licensing Board Lookup
Most states run a free online lookup through their licensing board. Enter the contractor's name or license number to see their status.
Search by license number when you have it. Name searches pull up too many matches.
The Idaho Division of Occupational and Professional Licenses and similar boards in other states show whether a license is active, expired, or suspended.
Checking License Status and Classification
Status tells you if the license is valid now; classification tells you what work it covers.
A license classified for handyman work may not cover electrical or HVAC work. Match the classification to your project.
- Active means the license is current and in good standing
- Expired means the contractor cannot legally work
- Suspended or revoked means stop and hire someone else
Reading a Contractor Certificate of Insurance Correctly
A certificate of insurance (COI) is a one-page summary of a contractor's coverage: insurer, policy numbers, coverage types, limits, and dates.
But a COI is not proof of coverage, it's a snapshot that can be faked or outdated.
Check these fields:
- The contractor's legal business name
- The insurance carrier's name
- Policy numbers for each coverage type
If the legal name on the COI doesn't match the contract, ask why.
How to Authenticate a Certificate of Insurance
Call the insurance agent or carrier listed on the COI. Use the phone number from the carrier's official website, not the number printed on the certificate.
This one step catches most fakes. Ask the agent to confirm the policy is active and the limits are correct.
Request that your name be added as a certificate holder. Some homeowners also ask to be listed as an additional insured, covered below.
Verifying General Liability and Workers' Compensation Coverage
Two coverage types matter most for home projects: general liability and workers' compensation.
General liability insurance pays for property damage and bodily injury caused by the contractor's work, a cracked foundation, a beam through a window, or a visitor hurt on site.
Workers' compensation insurance pays for worker injuries on the job. Most states require it for contractors with employees.
Confirm both policies are active before work starts.
How to Tell If the Coverage Limits Are Actually Enough
A $1,000,000 general liability limit sounds impressive until you run the numbers. How to pressure-test it:
- Compare the limit to your home's replacement cost, not its market value. A $300,000 home in a high-cost rebuild market might cost $500,000 or more to reconstruct. If the contractor's limit is below that, a total-loss scenario could leave you chasing the contractor personally.
- Add the injury exposure. A single serious fall from a roof can generate medical bills and lost-wage claims that run into six figures. General liability limits need headroom for both property damage and bodily injury.
- Check whether the limit is per-occurrence or aggregate. A $1,000,000 per-occurrence limit with a $1,000,000 aggregate means the policy is exhausted after one claim. A $2,000,000 aggregate gives more cushion if multiple issues arise.
Smaller contractors often carry the state minimum, well below what a major renovation requires. If the limit looks thin, ask the contractor to raise it or find one who carries more.
Exclusions That Quietly Leave You Exposed
A policy can be active, meet your limit threshold, and still deny your claim because of an exclusion. Read the exclusions page, not just the declarations page. Common exclusions:
- Roofing work. Many general liability policies exclude or sublimit roofing because of the fall and water-intrusion risk. If your project involves a roof, confirm the policy specifically covers it.
- Subcontracted work. Some policies exclude damage caused by subcontractors the named insured hired. If your contractor uses subs, this exclusion can shift the loss back to you.
- Faulty workmanship. General liability typically covers the result of defective work (the water damage) but not the cost to redo the defective work itself. That gap is why some homeowners also ask about a surety bond or a contractor's warranty.
Ask the contractor's agent directly: "Does this policy cover residential [roofing / remodeling / electrical] work at my address, and are there any exclusions that would apply to this project?" Get the answer in writing if you can.
Policy Dates: Why the Effective and Expiration Dates Matter Mid-Project
- Effective date shows when coverage began. A policy that started last week is fine; one that started the morning you asked deserves a second look.
- Expiration date shows when it ends. If it expires before your project finishes, coverage stops that date, even if the crew is still on site.
For projects longer than a few weeks, calendar the expiration date and request a renewed certificate before it lapses. A mid-job lapse is a common way homeowners end up uncovered.
Subcontractors, Additional Insured Status, and Coverage Continuity
The crew on your job may not all work for the contractor you hired. Subcontractors often handle electrical, plumbing, or HVAC work.
Each subcontractor needs their own insurance.
Ask the contractor to list every subcontractor and provide proof of insurance for each.
Additional insured status means you're added to the contractor's policy for your project.
Coverage continuity means the policy stays active for the whole project.
State rules vary: some require contractors to carry workers' compensation, while others allow exemptions for small operations.
Your Contractor Insurance Verification Checklist
Use this checklist before you sign anything or let a crew start.
| Step | What to Check | Why It Matters |
|---|---|---|
| 1 | License number and status | Confirms legal right to work |
| 2 | License classification | Matches license to your project type |
| 3 | Certificate of insurance | Shows coverage types and limits |
| 4 | Legal name match | Ties policy to the right business |
| 5 | Policy dates | Confirms coverage is active now |
| 6 | Call the carrier | Authenticates the certificate |
| 7 | General liability limits | Protects against property damage |
| 8 | Workers' compensation | Covers on-site injuries |
| 9 | Subcontractor proof | Extends coverage to every worker |
| 10 | Additional insured status | Adds you to the policy |
What to Do When You Cannot Verify Coverage
Sometimes the paperwork doesn't add up: the contractor dodges questions, the carrier can't confirm the policy, the dates don't line up, or the legal name doesn't match the contract.
Stop. Do not sign, pay a deposit, or let work begin until coverage is confirmed. An unverified contractor is an uninsured contractor until proven otherwise, and the cost of being wrong lands on you.
A Step-by-Step Escalation Sequence
Work through these in order. Move to the next step only when the previous one fails.
- Pause in writing. Send a short email or text: "Before we proceed, I need a current certificate of insurance showing active general liability and workers' compensation coverage, plus confirmation from your agent that the policy is in force." Written requests create a record and filter out contractors hoping you won't ask.
- Set a firm deadline. Give 24 to 48 hours. A legitimate contractor can produce proof the same day; one who needs a week is uninsured or stalling.
- Call the carrier yourself using independently sourced contact information. Look up the insurer's number on their official website, never the number printed on the certificate, which can route to a fake answering service. Ask the agent to confirm the policy number, named insured, effective dates, and coverage types.
- Verify the license status with the state licensing board. If the license is expired, suspended, or revoked, the insurance question is moot, walk away and report it.
- Request corrected documentation in writing. If the certificate has errors (wrong legal name, wrong address, expired dates), ask for a corrected certificate issued directly by the agent, not a re-typed version from the contractor.
- Escalate to the licensing authority. If you suspect the contractor is unlicensed or presenting a fraudulent certificate, file a complaint with your state licensing board. Many boards have an online form, and insurance fraud can also be reported to the state department of insurance.
- Hire someone else. This is not a failure. There are more contractors than projects. The one who can't produce proof is the one you don't want.
Protecting Money You've Already Paid
If you've already paid a deposit to a contractor whose coverage you can't verify, your options narrow but don't disappear:
- Stop further payments immediately. Do not pay another installment until coverage is confirmed.
- Put the request in writing and keep copies. A paper trail matters if you end up in small claims court or arbitration.
- Check whether your contract has a cancellation or refund clause. Many states give homeowners a short right-to-cancel window on home improvement contracts signed at the home. Your state's consumer protection office can confirm the rules.
When to Walk Away vs. When to Give a Second Chance
Not every snag is a red flag. A contractor who says "I'll email it this afternoon" and does is fine. One who says any of the following is not:
- "I don't need insurance, I work alone." (Sole proprietors still need general liability, and many states still require workers' comp or an approved exemption.)
- "The certificate is at my other office."
- "My agent is hard to reach."
Experience is not a substitute for coverage. The paperwork takes minutes to produce. If they won't, walk away.

Frequently Asked Questions
How do I verify that a home contractor is insured?
Ask the contractor for a certificate of insurance, then call the insurance carrier directly to confirm the policy is active. The certificate lists the carrier name, policy number, and coverage dates. Contact the carrier's phone number, not the one on the certificate, to avoid a falsified document. Confirm the legal name on the policy matches the contractor's business name. Also check the contractor's license status through your state licensing board to confirm the business is registered and in good standing.
Is a certificate of insurance enough to verify a contractor's coverage?
No. A certificate of insurance is a snapshot, not proof of active coverage. Policies can lapse or be canceled after the certificate is issued. To truly verify insurance for home contractors, call the insurance carrier and confirm the policy is still active on the day work begins. Ask about coverage limits and whether the policy covers the specific type of work being done. A certificate alone does not protect you if the policy has lapsed.
Can I call a contractor's insurance company to confirm coverage?
Yes, and you should. Call the insurance carrier's main line, not a number the contractor provides, and give them the policy number and contractor's legal name. Ask whether the policy is active, what the effective and expiration dates are, and what coverage limits apply. The carrier can confirm general liability and workers' compensation status. This step takes about ten minutes and is the most reliable way to verify a contractor's insurance before work starts.
Should I ask a subcontractor for proof of insurance too?
Yes. If the contractor hires subcontractors for your project, each subcontractor should carry their own general liability and workers' compensation coverage. Ask the general contractor to provide certificates for every subcontractor who will be on your property. Call each carrier to confirm active policies. If a subcontractor is injured on your job site without workers' compensation, you could face liability. Requesting additional insured status for yourself on the policy adds another layer of protection.
