San Antonio's shifting clay soil puts constant pressure on under-slab pipes. We find and fix slab leaks with precision so your home stays solid.
Not sure if you have a problem? Look for these common indicators.
A warm patch on tile or hardwood usually means a hot-water supply line under the slab is leaking. Walk barefoot to check.
A faint hissing or rushing sound beneath the foundation when no fixtures are on is a classic slab leak indicator.
New cracks in drywall, baseboards, or the exterior foundation can be caused by soil erosion from a slab leak undermining support.
Warped hardwood, loose tile, or damp carpet — especially in one area — often signals water pooling beneath the slab.
A slab leak can waste hundreds of gallons per day. If your SAWS bill jumped significantly with no change in usage, suspect a slab leak.
Water collecting under your foundation creates a damp environment that produces a musty, mildew odor even when the surface looks dry.
We pinpoint the exact leak location using acoustic and electronic detection — no guesswork, no unnecessary demolition.
We present spot repair, pipe lining, and reroute options with clear pricing so you choose what fits your situation.
All slab work is done with care to minimize impact on your foundation. We patch and restore concrete after the repair.
Slab leak repairs carry a 5-year warranty on parts and labor.
Slab leaks are one of the most common and most damaging plumbing problems in San Antonio. The city sits on expansive clay soil that swells when wet and shrinks when dry, creating a cycle of ground movement that stresses the copper and cast iron pipes running beneath your foundation. Over time, this movement causes joints to separate and pipe walls to develop pinhole leaks.
Left untreated, a slab leak can erode the soil supporting your foundation, cause cracks in walls and floors, create mold problems, and drive your water bill through the roof. The good news: modern repair techniques often don't require jackhammering your entire slab.
TruFlo offers multiple repair methods — spot repair, epoxy lining, and rerouting — and we'll recommend the one that makes the most sense for your home's age, pipe material, and the location of the leak. Every slab leak repair comes with a written warranty.
