Best Plumbing in Dallas, TX — 73 Vetted Contractors

Use the Texas State Board of Plumbing Examiners (TSBPE) online license search. Ask the company for its Responsible Master Plumber's name and license number, then confirm the license is active and review any disciplinary history. Texas plumbing companies are expected to work under a master plumber, so if a company cannot name one, treat that as a red flag. You can also file a complaint with TSBPE if work is unlicensed or substandard.

Generally yes. Within the City of Dallas, replacing a water heater is typically a permitted job handled through Dallas Development Services, and a licensed plumber should pull it. Permits matter for safety (gas, venting, temperature and pressure relief) and for insurance and resale. If you live in a neighboring city such as Irving or Garland, that city's permit office applies instead, so confirm jurisdiction first.

Spot repairs that involve locating the leak and breaking through the slab commonly run about $1,500 to $4,500. Rerouting a line through the attic or walls, or repiping the house, costs more, with whole-house repipes often between $4,000 and $12,000 or more depending on size and finishes. Prices vary widely, so get two or three quotes and insist on electronic leak detection before anyone cuts concrete.

Generally, the homeowner is responsible for the private sewer lateral from the house to where it connects to the city main, and for the water line from the meter into the house. The city handles the main and the meter itself. Boundaries can vary by location, so contact Dallas Water Utilities if you are unsure. A camera inspection can show whether a backup is a house problem or a main problem.

Dallas does not freeze often, but when it does, homes are unprepared. Winter Storm Uri in February 2021 left thousands of homes with burst pipes. Before winter, insulate exposed pipes and attic lines, cover outdoor faucets, and find your main shutoff. Know how to drip faucets on a hard-freeze night. Repair crews get booked solid after freezes, so fall prep is much cheaper than an emergency in January.

Moderately hard water leads to scale buildup that insulates the heating element or burner and corrodes the tank over time. Attic installations add heat stress, and high household water pressure can shorten lifespan. Flushing a tank yearly, replacing the anode rod when needed, and having a pressure regulator and expansion tank installed can extend life. Tank units commonly last roughly 8 to 12 years, though results vary.

For minor tasks like swapping a showerhead, usually yes. But in Texas, plumbing work done for pay generally must be performed by licensed plumbers or registered apprentices under a master plumber, and that includes gas piping, water heaters, and sewer work. Unlicensed work can void warranties, fail inspection, and complicate insurance claims. When in doubt, check the license on the TSBPE site before you agree to anything.
