Stop Slab Leaks Before They Undermine Your Foundation
A slab leak — a water or drain line that leaks beneath your home's concrete foundation — is one of the most destructive plumbing problems a homeowner can face. Left untreated, the water erodes the soil under your slab, causing foundation shifting, expensive structural damage, and dangerous mold growth. Texas Legacy Plumbing specializes in slab leak detection and offers multiple repair methods to fix the problem with as little disruption to your home as possible.

A hot-water line leaking under the slab heats the concrete above it — you can often feel this through tile or hardwood flooring.
With all plumbing fixtures off, press your ear near the floor. Gurgling or hissing sounds are a red flag.
Excess moisture that has no obvious source appearing around your home's perimeter can indicate an underground line failure.
Slab leaks can waste hundreds of gallons per day, driving your bill up dramatically.
As water saturates the ground under your slab, the foundation shifts — manifesting as cracks indoors.
Moisture migrating up through the slab creates the perfect conditions for mold and mildew growth beneath floor coverings.
We believe in transparency at every step. Here's exactly what to expect when you call Texas Legacy Plumbing.
We use acoustic amplifiers and electronic correlators to listen through your slab and pinpoint the leak location to within inches — no guessing, no unnecessary breaking of concrete.
Infrared cameras reveal heat signatures where hot-water lines are leaking, giving us a visual confirmation of location before we open anything.
Depending on your home's age, pipe material, and leak location, we recommend the best repair method: direct access repair, pipe rerouting, or epoxy pipe lining.
When direct repair is the best option, we break the slab only at the exact leak location — never larger than necessary — and make a permanent, code-compliant repair.
For older or corroded pipe systems, we may reroute the affected line through walls or ceilings, bypassing the problem entirely without disturbing the slab.
Every repair is pressure-tested before concrete and flooring are restored. We also document everything for insurance purposes.

Very serious. Water eroding soil beneath your foundation can cause permanent structural damage within months. A slab leak should be addressed within days of discovery, not weeks.
Detection typically takes 2–4 hours. The repair itself depends on the method chosen — a direct access repair may take 1–2 days; pipe rerouting can often be done in a single day.
In most cases, yes. We will need to shut off your water for portions of the repair, but we schedule work to minimize disruption.
Many homeowner's policies cover sudden and accidental slab leaks, though coverage varies. We provide full documentation to support your claim.
If your home has aging copper or galvanized pipes, we may recommend a full pipe rerouting or repiping to prevent future leaks rather than spot-repairing repeatedly.
