How to check a contractor's license

Start with the state license lookup

If a remodeler says they are licensed, ask for their full legal business name and license number. Then go to your state contractor licensing website and search it yourself. In some places, licensing is handled by the state. In others, the city or county may also require local registration.

You want to see that the license is active, in the right trade, and issued to the same company that will be on your contract. If the quote says one company name but the license belongs to someone else, stop and ask why.

This matters because license rules, permit rules, and enforcement vary by state and city. A contractor may be legal in one place and not properly registered in another. Always verify it yourself instead of taking someone’s word for it.

What to match before you sign

Checking a license is not just typing in a number. You need the details to match across the quote, contract, permit paperwork, and insurance.

Use this simple checklist:
1. Business name matches exactly.
2. License number matches exactly.
3. License status says active, current, or equivalent.
4. The license type fits the work, like general remodeling or the trade being hired.
5. The address and contact information are consistent.
6. The person signing the contract is authorized for that business.
7. The insurance certificate shows the same business name.

If a contractor says, "We use another company’s license," that is a major red flag. If they say, "The license is pending," treat that as unlicensed until you can verify otherwise.

Also verify insurance and permits

A license and insurance are not the same thing. A licensed contractor should also carry appropriate insurance, and you should verify it yourself. Ask for a current certificate of insurance and check that the company name matches the license and contract.

Depending on the job and your state, workers' compensation coverage may also matter if they have employees. Rules vary, so ask what coverage they carry and confirm it with the insurer or agent listed on the certificate if needed.

For remodels that require permits, ask who will pull the permit. In many cases, the licensed contractor should do that, not the homeowner. If someone asks you to pull a permit for work they are controlling, ask your local building department what that means in your area before agreeing.

This is general information only, not legal or construction advice. Permit and licensing rules vary by city and state, so check with your local building department and hire licensed, insured contractors.

Big red flags that often show up with license problems

People get burned when they skip this step. A fake, expired, or borrowed license often comes with other warning signs.

Watch for these red flags:
- Large cash-only deposits
- No written contract
- No license number on the bid when your state normally requires it
- Pressure to "sign today"
- Asking for full payment up front
- A different company name every time you see paperwork
- Refusing to provide insurance proof
- Telling you permits are "not needed" without a clear reason

A good contractor does not get offended when you verify their license and insurance. They expect it. They should be able to explain their business name, scope, payment schedule, and permit plan clearly.

What a license check can and cannot tell you

A valid license is a basic screen, not a guarantee of quality. It can help you confirm that the business is registered as required in that area, but it does not promise good communication, clean work, fair pricing, or a smooth schedule.

You still need to compare written quotes, ask what is included and excluded, and check recent references. For a kitchen, bathroom, basement, addition, or whole-home remodel, get more than one written quote if you can. Remodel prices vary a lot by scope, materials, the home, the city, and the contractor.

As a very general example, homeowners often see bathroom remodel quotes from around $8,000 to $30,000+, kitchens from roughly $15,000 to $80,000+, and larger projects much higher. Those are not quotes and not promises. They just show why checking credentials before signing matters. You can read more at costs and other guides.

If you want help finding someone legitimate

Keystone Reno is a free matching service, not a contractor or design firm. We do not perform remodeling work. We help homeowners get connected with vetted, licensed, insured remodeling contractors near them so they can compare options and decide who to hire.

The service is free for homeowners. You stay in control: compare written quotes, ask questions, choose who to hire, and hold final payment until the work is done and you are satisfied.

If you want, you can get matched or read more in our help center. We only collect contact and project intent details like your name, phone, email, project type, city or ZIP, timeline, and preferred language.
