Slab Leak Detection & Repair in Katy, TX
A leak under your foundation compounds silently — eroding soil, cracking the slab, feeding mold. We pinpoint it without tearing up your floor, then fix it with the least invasive method that will last.
Why slab leaks happen in Katy specifically
The expansive clay soils common throughout Houston and Fort Bend County contract and expand with seasonal moisture, putting physical stress on buried pipes. Add the other usual causes — copper corrosion from soil and water chemistry, pipes installed without proper support, water pressure above 80 PSI, and abrasion where pipe rests against concrete — and slab leaks are a matter of when, not if, for many area homes.
Understanding the root cause is what lets us recommend the right long-term repair instead of a temporary fix. Founded in 2000, we've handled thousands of slab leak repairs across West Houston, Fort Bend County and Harris County — we know the pipe materials, soil conditions and construction styles common here and how they affect repair strategy.
Insurance documentation included
Many homeowners policies cover the cost of accessing and repairing a slab leak, as well as the resulting water damage — but claims need evidence. We provide the detailed reports and documentation your insurance company needs to process the claim quickly.
Repairs are quoted in a detailed written estimate before any work begins — costs typically range from $500 to $4,000+ depending on location, method and severity, and most repairs finish within 1–3 days.
What we handle
Slab Leak Detection & Repair work we handle every week
Electronic Leak Detection
Amplification equipment listens for pressurized water escaping beneath the slab — pinpointing the leak without unnecessary digging.
Thermal Imaging
Infrared cameras spot the temperature change a hot-water-line leak creates in your floor — fully non-invasive.
Acoustic Detection
High-frequency sensors analyze sound patterns in the pipes — accurate even under several inches of concrete.
Epoxy Pipe Lining
For internal corrosion, a structural epoxy liner coats the inside of the existing pipe — sealing the leak with zero concrete cutting.
Pipe Re-Routing
A new line through walls, attic or crawl space bypasses the damaged section entirely. No jackhammering required.
Tunneling & Replacement
For severe leaks or old galvanized pipe, we tunnel beneath the foundation and replace the line while protecting the slab's structural integrity.
Pressure Testing
Every repair ends with a pressure test on the affected lines — the leak is confirmed resolved before we leave.
Triage

281-601-1513How do I know if I have a slab leak?
The common signs: an unexplained spike in your water bill, the sound of running water when everything is off, warm or wet spots on the floor, new cracks in walls or flooring, and reduced water pressure. Any of these is reason to call for a detection visit.
How much does slab leak repair cost in Katy?
Typically $500 to $4,000+ depending on the leak's location, the repair method, and severity. We provide free estimates so you know the full cost upfront before any work begins.
Can a slab leak be fixed without breaking the concrete?
Often, yes. Epoxy pipe lining seals corrosion leaks from inside the pipe, and re-routing runs a new line through walls or attic to bypass the damaged section — both avoid jackhammering entirely. We recommend the least invasive method that will actually last.
How long does the repair take?
Most repairs finish in 1–3 days. Epoxy lining or a re-route is often done in one day; tunneling repairs may take 2–3.
Does homeowners insurance cover slab leaks?
Many policies cover accessing and repairing the leak plus resulting water damage, though coverage varies. We provide the detailed documentation your insurer needs to process the claim quickly.
