Plumbers in Flower Mound

The town says plumbing contractors doing Chapter 14 work must register with Flower Mound and hold a state license; registration lasts one year from the application date. The state license comes from the Texas State Board of Plumbing Examiners, which issues Tradesman Plumber-Limited, Journeyman, Master and Inspector licenses, each renewed yearly.

• Search the name on TSBPE's Public License Search.
• Read the bid: under Occupations Code Chapter 1301 every proposal, invoice or contract must show the Responsible Master Plumber's name and license number and TSBPE's contact details.
• The Responsible Master Plumber pulls permits and requests inspections, and must keep $300,000 of liability insurance on file.

Sprinkler systems and Flower Mound irrigation permits

Irrigation systems are on the town's permit list. Once a system runs, it follows the two-day schedule: even-numbered homes Tuesday and Friday, odd-numbered Wednesday and Saturday, never 10 a.m. to 6 p.m. (as of October 2026). Ask the installer to set the controller to your days.

Cross Timbers lots and wastewater

The Cross Timbers Conservation Development District is mostly homes on two acres or more, and the Master Plan doesn't provide sewer there. Ask the seller or the town how your lot's wastewater is handled before hiring for a drain or line job.

Water supply and freezes

The town delivers water it gets mostly from the Upper Trinity Regional Water District and partly from Dallas Water Utilities. Texas health officials linked 246 deaths to the February 2021 winter storm; know where your shutoff is before a hard freeze, and ask your irrigation installer how the system should be winterized.

State law doesn't require a plumbing license for work in your own homestead, but check the town's permit rules before you start.

HomeGuide's June 2026 Dallas guide is the closest published benchmark: $182 to $500 for most home jobs, about $340 on average, $45 to $200 an hour and $100 to $250 for a service call. Those are Dallas numbers. A burst pipe repair runs $400 to $2,000 nationally. The full guide is on our Texas plumber page.
