Slab Leak Detection & Repair in Wimberley
A slab leak hides where you cannot see it, in the water lines running under your concrete foundation. Left alone, it wastes water, drives up bills, undermines the slab, and eventually shows up as damaged flooring or a cracking foundation. The frustrating part is that it can run for months before anything obvious appears.

Request slab leak
Homes on slab foundations around Wimberley face the usual culprits, plus a couple specific to this area. Hard Trinity Aquifer water corrodes copper from the inside over time. Rocky, shifting soil and the region's dramatic wet-dry swings stress buried lines. And the 2021 freeze cracked pipe in places nobody could see until it thawed and started leaking.
The old way to find a slab leak was to break up concrete until you hit it. We do not work that way. We use electronic leak detection and pressure testing to pinpoint the leak before we open anything, so the repair is targeted. Then we give you honest options, a direct spot repair, a reroute around the failed section, or a repipe if the whole system is going.

Signs you need slab leak in Wimberley
- An unexplained jump in your water bill
- The sound of running water when everything is off
- Warm or hot spots on the floor, often a hot-water line leak
- Cracks appearing in flooring, tile, or the foundation
- Damp, buckling, or discolored flooring
- A drop in water pressure with no other cause
- A musty smell or mold near the base of walls
What our slab leak service includes
Electronic leak detection
We locate the leak under the slab with acoustic and pressure equipment before any concrete is touched.
Pinpoint accuracy
Precise location means a targeted repair instead of breaking up floor across the house hunting for the source.
Repair options
We lay out spot repair, rerouting the line, or repiping honestly, based on the pipe's condition and your situation.
Minimal disruption
Where a reroute avoids jackhammering your slab, we favor it, keeping the mess and downtime down.

We pressure test after the repair to confirm the leak is truly gone and no other line is compromised.

Slab Leak FAQs
No. We locate the leak electronically before opening anything, so we know exactly where it is. That means a targeted repair rather than breaking up concrete across the house guessing at the source.
It depends on the pipe. A single leak in otherwise sound piping is often a spot repair. If the line is corroding from hard water in several places, rerouting or repiping that run saves you from repeated repairs. We tell you honestly which fits.
Common signs are an unexplained high water bill, the sound of running water with everything off, warm spots on the floor, or cracking flooring. If you notice these, we can confirm it with a meter check and pressure test before committing to any repair.
Many policies cover the cost of accessing the leak and repairing resulting damage, though the pipe repair itself and coverage details vary widely. We document the leak location, cause, and repair, which supports a claim, but we do not file it. Review your policy's language on plumbing and slab access, and keep our written estimate on hand.
A slow slab leak will not flood the house today, but it wastes water, undermines the foundation, and grows costlier the longer it runs. Warm floors, a spiking water bill, or the sound of running water with everything off mean you should have it located soon. Catching it early keeps a spot repair from becoming a repipe.
