Leak Detection in Austin, TX

Leak Detection in AustinLeak detection in Austin often means finding a slab leak in a home on shifting clay. East of I-35, Blackland Prairie soils shrink during long, hot summers and swell after heavy rain, and that movement stresses copper and PEX supply lines under the slab. Warm floor spots, the sound of running water and rising bills are the usual clues. Accurate location keeps the repair small and helps decide between direct repair and rerouting.

What’s different about leak detection in Austin

Soil-driven leaks

Leaks often appear after long dry spells or sudden heavy rain, when clay movement peaks.

Irrigation-heavy yards

Isolating sprinkler systems first separates yard leaks from house leaks.

Reroute vs. repair

After a second slab leak, rerouting through the attic avoids repeated concrete work, though attic lines need freeze protection.
