1. Get the license number from the contractor

   Ask for the license number before anything else. A licensed contractor has it on the bid, the contract, the business card and often the truck. If someone says "we're licensed and insured" but can't produce a number on the spot, treat that as your first answer.

   Texas licenses most trades through TDLR, and each trade has its own number format. Ask which agency issued the license as well as the number.

2. Search the number on the official site

   Search the number on the official site. In Texas that is the Texas Department of Licensing and Regulation (TDLR) (opens official site) license search at tdlr.texas.gov. Search by the number first; a name search can miss a business that is licensed under a different legal name.

   You can also look the contractor up here . Our results come from Texas's own published license file, so they are a fast first check, but the official record is live and also shows complaints and discipline.

   Texas splits licensing across more than one board: Texas Department of Licensing and Regulation (TDLR); Texas State Board of Plumbing Examiners (TSBPE). Electrical, plumbing or HVAC work may be licensed by a different board than general construction, so make sure you are searching the right one.

3. Read the record: status, name, expiration

   Three things have to line up. The status should say active, current or valid, not expired, inactive, suspended or revoked. The name on the license should be the business or person on your contract. The expiration date should be after the day the work finishes, not just after the day you sign.

   Look for a complaints or discipline section on the record. Most Texas license searches show open complaints, past discipline and sometimes bond claims. One old complaint on a long-running license is normal; several recent ones are not.

4. Check that the license covers your job

   Texas licenses electrical, plumbing and HVAC work at the state level. A license covers one kind of work, so a roofer's license doesn't cover your electrical panel, and a specialty license doesn't cover a whole remodel. Check that the classification or license type on the record matches the job you are hiring for.

   Hiring for one trade? Texas may license it through a different board. See electricians in Texas , plumbers in Texas or HVAC contractors in Texas .

5. Check the city or county license too

   Texas licenses some trades statewide and leaves others to cities and counties. If the state search comes up empty for the trade you need, the license may be local. Check with the building department where the work will happen.

   Local searches we've confirmed: City of San Antonio (opens official site) (Development Services Department); City of Dallas (opens official site) (Development Services, Building Inspection). Not listed? Call the building department for your city or county.

6. Know the small-job line

   We haven't confirmed an official small-job exemption for Texas. Assume any job that needs a permit needs a licensed contractor.

7. Ask for proof of insurance

   We haven't confirmed a state insurance or bond requirement for Texas, so don't assume there is one.

   Whatever the state requires, ask for a certificate of insurance made out to you, and call the insurer on the certificate to confirm it is current. A license search tells you the contractor met the requirement when the license was issued or renewed, not that the policy is still paid.

8. Make sure the permit is pulled in the contractor's name

   Any job that needs a permit should have the permit pulled by the contractor, under the contractor's license. A contractor who asks you to pull the permit as the homeowner is usually hiding a license problem. Permits come from the building department for your city or county.

9. If something goes wrong, file with the board

   If the contractor stops showing up, does work the permit doesn't cover, or the license turns out to be wrong, put it in writing to them first, stop paying, then file a complaint in Texas (opens official site) . Boards can suspend licenses, which gets attention a lawsuit doesn't.
