Leak detection for Fort Worth homes
Hidden leaks waste water and rot framing before anyone sees them. In dry climates a slow leak can evaporate as fast as it drips, so a stain may never appear. The first sign is often a water bill that jumps between seasons that should match.
For the full guide, including what you can safely do before a plumber arrives, see leak detection explained.

Local conditions
Leak detection in Fort Worth: what's different
Expansive clay under Fort Worth slabs moves with wet and dry seasons, stressing supply lines and causing slab leaks, often after drought ends with heavy rain. Warm spots on the floor, cracked tile and a rising bill are the usual signs.
A plumber confirms the leak at the meter, then uses acoustic listening and thermal imaging to pinpoint it. Older pier-and-beam homes in Fairmount and Ryan Place let plumbers reach many lines from the crawl space instead.
