How to find a licensed plumber

We do not run a directory or take referral fees. Here is how to find and vet a licensed plumber yourself, in about ten minutes.

1. Check the license

Search your state licensing board for a plumbing license lookup and confirm the license is active and matches the business name. Licensing is set by each state, and in some places by the city or county; our guide to plumbing license requirements explains how it works.

2. Confirm insurance

Ask for a certificate of liability insurance, and workers’ compensation if the company has employees. A legitimate contractor will send it without hesitation.

3. Get written quotes

Get two or three written quotes with the same scope, and compare them against our guide to how much a plumber costs. Ask whether the work needs a permit; see plumbing permit requirements.

4. Know the red flags

Be wary of cash-only pricing, no written estimate, a large deposit before any work, pressure to decide on the spot, or an offer to skip the permit. If you are weighing a handyman instead, read can a handyman do plumbing first.

In an emergency

Shut off the water before you call anyone. Our burst pipe checklist and plumbing emergency guide cover the first steps, and whether homeowners insurance covers it.
