Plumbers in Austin

State law makes every Texas city of more than 5,000 people regulate plumbing by ordinance and require a permit, water heaters included. The exceptions are small jobs: fixing a leak, or replacing a faucet, ballcock, garbage disposal or toilet. Austin is far above that size, so a new water heater, a repiped bathroom or a sewer line repair should come with a permit.

In Austin, permits, fees and some inspections run through the Austin Build + Connect (AB+C) Portal at Austin Development Services. The Responsible Master Plumber (RMP) is the person the law makes responsible for pulling permits and requesting inspections, so the permit should carry that plumber's license. Before the city issues it, the permit office has to confirm with the Texas State Board of Plumbing Examiners (TSBPE) that the RMP has insurance on file.

Plumbing installed under a permit has to pass inspection by a licensed plumbing inspector. Ask for the permit number on day one, look it up in AB+C, and hold the final payment until the inspection passes.

1. Read the quote. Every written Texas plumbing proposal, invoice or contract must show the RMP's name and license number plus TSBPE's name, mailing address and phone number. A quote without them falls short of state rules.
2. Search the license. TSBPE's Public License Search finds a plumber by name, license number, city or county. The four licenses are Tradesman Plumber-Limited, Journeyman, Master and Plumbing Inspector, and each renews yearly.
3. Ask about insurance. The RMP must keep at least $300,000 of commercial general liability insurance on file with TSBPE.
4. Check the Austin registration. Plumbing contractors must register with the city's Building and Trade Contractor Services before permit work begins and update that registration every year.
5. Look at the plumber on site. License and registration holders must carry the card while working, and the van should show the company name and the RMP's license number.

Complaints go to TSBPE on its General Complaint Form, or by phone at (512) 936-5200. Texas's home-solicitation cancellation law (Business and Commerce Code Chapter 601) generally doesn't cover plumbing you called for, so read the contract before you sign.

What an Austin plumber costs

Austin quotes vary, so treat HomeGuide's national figures as a starting range: $45 to $150 an hour, average jobs of $125 to $450, and service-call fees of $50 to $200. A burst pipe repair runs $400 to $2,000 nationally, or about $150 to $250 per linear foot. The Texas plumbing guide breaks costs down further.

Austin Water lines, backflow and irrigation

Austin Water supplies the water and also runs the wastewater system, responding to sanitary sewer overflows, so ask the utility about a backup at the street. Lawn sprinkler systems are on a one-day-a-week schedule under the Conservation Stage rules in force as of September 2, 2025, and stages change, so check Austin Water's current schedule. A one-day schedule is a good moment to have a leaking zone repaired.

Anyone who tests or repairs a backflow prevention assembly in Texas needs a TCEQ Backflow Prevention Assembly Tester license, valid for three years. A TCEQ customer service inspection checks private water lines for cross-connections and lead before service starts to new construction; plumbers with the Water Supply Protection Specialist endorsement can perform one.

Freeze-proofing an Austin home

Texas health officials confirmed 246 deaths related to the February 2021 winter storm, a reminder that Central Texas freezes can be severe. Ask a plumber in the fall to look at exposed lines in the attic, garage and exterior walls, and pair that visit with an Austin AC and heating check. City-wide rules for every trade are on the Austin hub, and plumbers in Round Rock are listed for comparison.
