Slab leak detection and repair, without tearing up your house

Electronic and acoustic leak locating pinpoints the leak first, so the fix is surgical, not exploratory.

A slab leak announces itself quietly: a water bill that doubles, a warm patch on the tile, the sound of running water at 3am with every faucet off. Ignore it and it erodes the soil under your foundation; in San Antonio's expansive clay, that's a foundation repair bill waiting to happen.

We locate before we cut. Acoustic and electronic detection, plus thermal imaging on hot-side leaks, narrows the leak to inches. Then you get three honest options with prices: direct access and repair (one spot, one fix), reroute overhead through the attic (skip the slab entirely, often cheaper and less invasive than people expect), or repipe if the system is failing everywhere.

Homes built in the 60s–80s with copper under the slab are the classic case: our clay soil shifts, the slab flexes, and the pipe wears through at the contact points. If you've had one slab leak in a house like that, the odds of a second are real. We'll tell you honestly whether a reroute now beats paying for detection twice.

Common questions

How sure is the detection? I don't want exploratory holes.
Modern acoustic and electronic locating pinpoints most leaks within a foot, usually inches. We mark the spot and commit to the flat repair price before we open the floor: if the leak isn't where we marked, the extra access is on us.
Repair the spot or repipe the house?
One leak in an otherwise healthy system: repair or reroute that line. Second leak in a 1970s copper-under-slab home: the math starts favoring reroute or repipe, and we'll show you the actual numbers side by side rather than push the big ticket.
Does homeowners insurance help?
Often, partially: policies commonly cover the access and the water damage, not the plumbing repair itself. We provide the detection report, photos, and itemized invoice your adjuster will ask for.
