Plumbers in Waco

The Texas State Board of Plumbing Examiners licenses plumbers in four grades: Tradesman Plumber-Limited, Journeyman, Master and Plumbing Inspector, each renewed every year. Apprentices register separately. Any company that advertises plumbing must secure the services of a Responsible Master Plumber, who keeps at least $300,000 of liability insurance on file with the board, pulls the permits and requests the inspections.

Look up the name or license number on TSBPE's Public License Search, which also searches by city or county, so you can run a McLennan County search. Texas law requires every written proposal, invoice or contract to carry the RMP's name and license number along with the board's name, address and phone. A quote on plain paper with no license number is a reason to keep looking. Licensees also have to carry their license on them while working, so it's fair to ask to see it.

Waco plumbing permits and registration

Texas cities over 5,000 people must require a permit for plumbing work, including water heaters, though fixing leaks or swapping a faucet, toilet or garbage disposal is exempt. Waco handles plumbing permits through its EnerGov Self Service portal. Before the city issues one, the contractor has to register the company, show proof of state licensing and file a certificate of insurance naming the City of Waco as certificate holder. Any city that issues plumbing permits must also confirm with TSBPE that the RMP has insurance on file. Ask your plumber for the permit number on any water heater, repipe or sewer job.

HomeGuide's published ranges give a Waco bid something to be measured against. Its national guide puts plumber rates at $45 to $150 an hour, typical jobs at $125 to $450 and service-call fees at $50 to $200, usually covering the first hour. Its Dallas guide (June 2026), the closest Texas figure it publishes, puts most residential jobs at $182 to $500, about $340 on average. A burst pipe repair runs $400 to $2,000 nationally (October 2025), or $150 to $250 per linear foot.

The Texas plumbing guide has the full cost table and hiring checklist.

The City of Waco supplies drinking water and runs the wastewater system in its service area, so for a leak near the meter or a sewer backup, ask the city utility whether the problem is on its side or yours before you book a plumber.

Texas health officials confirmed 246 deaths related to the February 2021 winter storm, a reminder of how hard a Texas freeze can be. Fall is the time to have a plumber insulate exposed lines, show you the main shutoff and check the water heater.

Backflow and inspections in Waco

Testing or repairing a backflow prevention assembly in Texas takes a TCEQ Backflow Prevention Assembly Tester license, valid for three years, which is separate from a plumbing license. A customer service inspection, which checks private lines for cross-connections and illegal lead materials, can be signed off by a plumber who holds the Water Supply Protection Specialist endorsement. Ask which credential covers the job you need.

If the project sits in a Waco Local Historic Landmark and changes the exterior, check whether it needs a Certificate of Appropriateness; interior plumbing doesn't.
