Leak Detection in Texas
Plumbers find hidden leaks by isolating sections of plumbing and testing them, then pinpointing the spot with acoustic listening, thermal imaging and moisture meters — so only a small, targeted opening is needed for the repair.

What drives leak detection calls in Texas
Slab leaks
When: Shrink-swell clay soils. What fails: Pipes under the slab crack as soil moves. What to do: Watch for rising water bills or warm floor spots, and ask for electronic leak detection.
Burst attic pipes
When: Rare hard freezes. What fails: Supply lines in attics and exterior walls split. What to do: Insulate attic lines, drip faucets and know where the main shutoff and meter key are.
Summer and drought: Clay soils shrink in drought, moving slabs and cracking pipes underneath.
Most Texas homes sit on concrete slabs, and many newer homes run water lines through the attic. Older homes in Houston, Dallas and San Antonio often have cast-iron drains under the slab that crack and scale over time.

How do I test for a hidden leak?
Turn off every fixture and appliance, note the meter, and check again after 30 minutes without using water. If it moved, there's a leak. Close the house shutoff and check again; if it still moves, the leak is on the service line.
