Slab Leak Detection & Repair in Katy, TX
A slab leak is a leak in the water lines running under a home's concrete foundation, and it's a real, recurring issue in Katy given the area's clay soil. Finding one early, before it damages flooring or the foundation itself, starts with knowing the real warning signs.
Warm Spot on the Floor or a Water Bill That Won't Explain Itself?
These two signs together are the classic slab leak pattern: a hot water line leaking under the slab warms the floor above it, and the constant, hidden flow shows up as a steadily climbing water bill with no obvious cause anywhere else in the house.
Why This Happens in Katy
Katy sits on expansive Gulf Coast clay soil that swells and shrinks with seasonal moisture changes, and that movement stresses the water lines running through and under a home's slab over years of exposure. Older homes with original copper supply lines are at the highest risk, though newer construction isn't entirely immune if the slab has settled unevenly.
Signs You Need Slab Leak Detection & Repair
A Warm Spot on the Floor
Usually a hot water line leaking directly beneath that section of slab.
Unexplained High Water Bill
The meter shows usage even with every fixture in the house off.
Sound of Running Water
Audible even when nothing is turned on, often coming from inside the floor.
Cracks in Flooring or Baseboards
Can indicate the slab itself has shifted from prolonged water exposure underneath.

How We Locate and Fix It
Electronic leak detection equipment pinpoints the exact location before any concrete gets touched, using acoustic listening and pressure isolation to narrow down the source. From there, the repair is either a direct spot penetration through the slab at that exact point, or a full reroute of the affected line above the slab, avoiding the buried section entirely. Either approach follows the Uniform Plumbing Code (UPC) as adopted in Texas for materials and installation, not just whatever stops the leak fastest.
Spot Repair or Full Reroute?
A Spot Repair Usually Makes Sense When
- This is the first slab leak found in the home
- The rest of the plumbing system is in good condition
- The leak location has straightforward access
A Reroute Makes Sense When
- This is a second or third leak in an aging system
- The existing pipe material is failing broadly
- Repeated slab penetrations aren't practical long-term
What Slab Leak Detection & Repair Costs
A direct spot repair typically runs on the lower end of this range. A full reroute costs more but avoids future slab penetrations. Exact cost depends on access and scope.
Sudden water damage from a slab leak is sometimes covered by homeowners insurance; the underlying repair to the leak itself typically isn't. Check your specific policy. Want your real number? Call (281) 626-9205.
Scope, Honestly
We locate and repair slab leaks in residential plumbing systems. We don't perform foundation structural engineering; if a leak has caused genuine foundation movement, that's a separate specialist scope we'll flag rather than take on ourselves.
What to Check or Shut Off
If you can locate your home's main shutoff, turning it off stops the leak from getting worse while you wait.
Avoid repeatedly walking on a warm or damp section of floor.
Take a photo of your water meter reading before and after a period with everything off, to help confirm the leak.
Don't cut into flooring yourself trying to find the source; that risks damaging a line you can't see.
Common Questions
Electronic leak detection equipment locates the source acoustically before any concrete is touched.
Often the resulting water damage is; the plumbing repair itself typically isn't. Check your specific policy.
A direct spot repair is often completed in a single day; a full reroute takes longer depending on the home's layout.
Often Booked Together
If the leak turns out to be from the water heater itself rather than a slab line, water heater repair covers that, and general leak detection covers leaks outside the slab as well.
