Slab Leak Detection & Repair in Houston

Most Houston homes are built on concrete slabs with water lines running underneath. Houston’s expansive clay soil swells when wet and shrinks during droughts, and that movement stresses those buried pipes until a joint or a corroded section gives way. Call (844) 212 9767 to reach a local plumber for slab leak detection and repair.

Slab Leak Warning Signs

• A water bill that jumps without any change in use
• The sound of running water when every fixture is off
• Warm spots on tile or concrete floors (a leak on the hot-water line)
• Damp or buckling flooring, or carpet that stays wet
• Musty odors or mold along baseboards
• New cracks in walls or floors
• The water meter’s leak indicator spinning with everything turned off

Quick check: turn off every fixture and appliance, note the meter reading, wait an hour without using water, and check again. Any movement means water is going somewhere.

How Slab Leaks Are Found

A plumber isolates the hot and cold lines to see which one is losing pressure, then pinpoints the leak using acoustic listening equipment, thermal imaging and line tracing — so any opening in the floor is small and in the right place, not exploratory.

Slab Leak Repair Options

• Spot repair through the slab — open the floor directly over the leak and fix that section. Best for a single, isolated leak.
• Tunneling — reach the pipe from outside, under the foundation, to avoid breaking up interior floors.
• Reroute — abandon the leaking line and run a new one through walls or the attic. Often the better choice when the pipe under the slab is old and likely to leak again. See water line repiping.

Slab Leaks and Mold

A slow slab leak can keep the area under flooring wet for months before it shows. If you smell mustiness or see discoloration, have the leak found and fixed first, then have the area dried and checked for mold.

Slab Leak FAQ

Does insurance cover slab leaks?

Many policies cover the cost of accessing the pipe and the resulting water damage but not the pipe repair itself. Coverage varies, so check your policy.
