Acoustic listening
Pressurized water escaping through a crack makes a distinct sound. Ground microphones and listening discs pick it up through concrete and soil, letting us trace a supply-line leak to its source without opening the slab.
Diagnosis, not demolition
Leak Detection in Austin & Marble Falls
Know exactly where before anyone cuts.
Electronic leak detection for Austin and Marble Falls homes — acoustic listening, thermal imaging, and pressure isolation that pinpoint hidden leaks under slabs, inside walls, and in yard lines. A detection visit tells you what's wrong and where; repair is a separate, informed decision.
How we find it
Three methods, zero guesswork
Every detection visit uses the right tool for the symptoms — not the same tool for every problem.
Thermal imaging
Hot-water leaks warm the surrounding concrete, flooring, or soil. Infrared cameras reveal that heat signature as a clear pattern on screen — the fastest way to map a hot-side slab leak's extent.
Pressure isolation
By capping and pressurizing lines section by section, we prove which run is losing water and rule out the ones that aren't. No ambiguity, no fishing expeditions — just the failing line, identified.
Detection vs. repair
Two scopes, each priced on its own
A detection visit answers one question: where is the water escaping, and what's the recommended fix? You get the location, the evidence, and a written report for your records or your insurance company. What happens next — spot repair, line reroute, or repiping — is your call, with real information in hand. If you already know you want the repair handled too, see our leak repair services.

FAQ
Leak detection questions, answered
How does electronic leak detection work?
Three tools do the heavy lifting: acoustic listening equipment that hears pressurized water escaping through tiny openings, thermal imaging cameras that spot the temperature signature of a hot-water leak, and isolated pressure testing that tells us which line is losing water. Together they narrow a leak to a precise location — often within inches — before anything is opened up.
Can you find a leak without tearing up my floors or walls?
That's the entire point of a detection visit. We diagnose first and open second. In most cases we pinpoint the leak's location with equipment alone, and any opening is limited to the small area where the repair will happen anyway. If we can't locate it, we'll tell you that honestly rather than start cutting.
How accurate is acoustic and thermal leak detection?
Very — when the conditions are right. Acoustic listening works best on pressurized supply lines; thermal imaging excels at hot-water leaks where the temperature contrast is clear. Drain and sewer leaks need different methods (camera inspection, smoke testing). We'll match the method to your symptoms instead of forcing one tool on every problem.
My water bill jumped but I don't see any water. Is that a leak?
Very possibly. Do the meter test: make sure no water is running anywhere, then watch your water meter for 15–30 minutes. If it's moving, water is escaping somewhere — under the slab, in a wall, or in the yard line. That's exactly when to call for a detection visit, before the hidden water becomes visible damage.
Will I get documentation for my insurance company?
Yes. Every detection visit includes a written report with photos documenting the leak location, the equipment readings, and the recommended repair. That's exactly what adjusters need to evaluate a claim. If repair work follows, see our leak repair services — detection and repair are separate scopes, each priced on its own.
