Frequently Asked Questions

Common questions about plumbers in Texas

Texas law allows homeowners to do basic repairs on their own primary residence but requires licensed plumbers for new construction, most permit work, and any work on rental properties.

Yes. Texas law requires plumbers to be licensed by the TSBPE. Always ask for a license number and verify it online.

Check the Texas State Board of Plumbing Examiners website at tsbpe.texas.gov to verify any plumber's license before hiring.

Signs include unexplained wet spots on floors, higher water bills, the sound of running water when nothing is on, and cracks in walls or flooring.

Tank water heaters typically last 8-12 years in Texas. The hard water in many Texas cities shortens lifespan — regular flushing extends it.

Most Texas homeowners should have main sewer lines professionally inspected every 2-3 years. If you have older pipes or mature trees near your sewer line, annual inspection is recommended.

Some noise is normal, but banging (water hammer), rattling, or squealing can indicate pressure issues, loose pipes, or a failing component.

Common causes include mineral buildup from Texas hard water, a failing pressure reducing valve, a partially closed shut-off valve, or a slab leak.

Most Texas plumbers charge $85-$150 per hour. Emergency or after-hours calls typically cost 1.5-2x the standard rate.

First, locate and turn off your main water shut-off valve. Then call a licensed emergency plumber. Knowing your shut-off valve location before an emergency is critical.
