High water bill, a damp spot, or the sound of running water you can't find? We pinpoint hidden, slab and underground leaks the same day with acoustic, thermal and pressure testing — accurate to within inches, with no demolition.
Turn off every fixture and appliance that uses water, then watch your water meter's leak dial (the small triangle or dial). If it keeps moving, water is escaping somewhere — that's a hidden leak.
Seeing active flooding instead? Shut off your main valve and call us — that's an emergency.
We pinpoint the exact spot before opening anything — so the repair is small, targeted, and clean.
Sensitive ground microphones and listening discs hear water escaping a pressurized pipe through floors, walls and soil.
Thermal cameras reveal the temperature change a hidden leak leaves behind walls, ceilings and under slabs.
Static pressure and fixture isolation tests confirm whether a line is losing water and narrow down which one.
Digital moisture and humidity meters map how far water has spread to trace it back to the source.
Pipe tracing and acoustic correlation follow metal and plastic supply lines underground so we dig only at the leak.
For drain and sewer lines, a camera shows breaks and intrusions on screen. We also use tracer gas on tough finds.
Leaks in pipes under your concrete foundation, found without breaking the whole floor. Slab leak repair

You get a flat, upfront price for the detection — and we credit that fee toward the repair when we do the work. Once we've pinpointed the leak, we fix small, accessible leaks the same visit and quote anything larger before starting.
| Standard leak detection visit | $250 – $500 |
| Complex slab / underground locating | $400 – $900 |
| Detection fee credited toward repair | Yes |
Estimates for guidance; your price depends on access and leak type. Hidden water damage is often covered by homeowners insurance, and our findings help document your claim.
A slow hidden leak quietly feeds mold, rots framing, ruins flooring and can undermine a foundation — all while running up your water bill. Catching it early is far cheaper than repairing the damage later.

We use non-invasive tools — acoustic listening discs, infrared thermal imaging, pressure testing, moisture meters and electronic line locators — to pinpoint a hidden leak to within inches before opening anything. No guesswork, no tearing the house apart.
A spiking water bill, the sound of running water with everything off, a warm spot on the floor, low pressure, damp or discolored spots, mold or a musty smell, and new foundation or yard wet spots.
A hidden slab, underground, or in-wall leak can waste hundreds of gallons with no visible sign. Turn off all water and watch the meter's leak dial — if it moves, you have a leak. We locate it the same day.
We combine acoustic listening, thermal imaging and line tracing to pinpoint a slab leak without breaking the whole floor. For the repair, see our slab leak repair service.
Yes — electronic line locating and acoustic correlation trace both metal and plastic supply lines underground, so we dig only where the leak is. See water line repair.
Most visits take one to two hours depending on access and leak type. We give you the findings and a repair quote before any work begins.
Typically about $250–$500, with complex underground or slab locating toward the higher end. You get an upfront flat price — and we credit the detection fee toward the repair.
