How plumbing licenses work in Texas

Plumbers in Texas are licensed by the Texas State Board of Plumbing Examiners (TSBPE), not by the agency that handles most other trades. A company that offers plumbing work to the public must operate under at least one Responsible Master Plumber (RMP) and must have a certificate of insurance on file with the board.

Master Plumber license numbers start with the letter M. The board says the RMP's license number should appear in the company's advertising, and that written estimates and invoices should include that number along with the board's contact information.

How to check a Texas plumber yourself

  1. Find the RMP license number on the company's website, truck or estimate.
  2. Look it up on the TSBPE public license search and confirm the status is current.
  3. Check that a certificate of insurance is on file.
  4. Get a written estimate before work starts.
