Find the leak before it costs you the foundation.

Acoustic and thermal leak detection across the Houston area. We pinpoint the leak, then quote the repair — no exploratory demolition.

Signs of a hidden leak

Mystery high water bill

Same usage but bill spiked — water is going somewhere it shouldn't.

Warm or wet spot on the floor

Classic slab leak — pressurized hot line under the slab.

Mildew or musty smell

Hidden moisture inside walls or under cabinets.

Cracks in walls or floors

A long-running leak can shift the foundation.

Sound of running water

Faint hiss or trickle when nothing is on — listen near the meter.

Pool keeps losing water

Pool plumbing leaks behave differently — same tools, find them too.

How we find it

We use acoustic listening gear (geophone-style) to hear the water moving through the leak point, plus thermal imaging on slabs and walls to spot temperature differentials. Pressure-isolation testing on each branch tells us which line is leaking, before we ever cut a wall.

Detection runs $295 for a single-line leak, more for a whole-house investigation. The detection fee is credited toward the repair if you use us for the fix.

Common questions

Most leak-detection appointments go same-day or next-morning. Active emergency? 24/7.

Detection is non-invasive. Repair may require opening a small section of slab, wall or ceiling — but we'll show you exactly where on a sketch before we do.
