Locate before we cut. Spot repair, reroute, or repipe — in plain English.
A slab leak doesn't have to mean a torn-up floor. We pressure-test and listen to pinpoint the leak before any concrete comes up — then walk you through all repair options with a written price for each.

Why slab leaks are so common in the Hill Country.
Two things hit pipes hard in this area. First, Hill Country soil is heavy in expansive clay — it swells when wet and contracts in drought. That constant movement stresses the pipes embedded in your foundation. Second, our groundwater is some of the hardest in Texas. That mineral-laden water attacks copper pipe from the inside, thinning the wall year after year until a pinhole breaks through.
Slab leaks aren't rare here — they're a routine call. The difference between a manageable repair and a six-figure floor restoration is whether you find the leak quickly, locate it precisely, and pick the right fix for the pipe's overall condition.
Signs You May Have a Slab Leak
You don't need all of these — any one of them is worth a pressure test:
How We Find It Without Breaking Concrete
Concrete comes up last — only once we have a pinpoint location. Here's how we get there:
Pressure Test
We isolate the hot and cold lines and hold pressure. If a line can't hold, we've confirmed a leak — and which line it's on — before any digging.
Acoustic Listening
We listen for the leak signature at multiple points above the slab. High-pressure water exiting a pin-hole makes a distinctive sound our equipment isolates.
Locate Above Ground
Only once we have a confirmed pinpoint location does concrete come up — at the spot, not on a guess. We mark it before we open anything.
Some of the Repair Options — Explained Honestly
We walk through some options, with a written price for each, before any work starts:
Spot Repair
One confirmed leak on otherwise sound, accessible pipe.
We open the slab at the pinpointed location, repair the pipe, and pressure-test. Least expensive if the pipe material is still in good condition.
Reroute
Pipe material is failing or the leak is in a difficult-access location.
We run new pipe through the walls or attic to bypass the slab section entirely. No slab opening needed. Good when the pipe is galvanized or corroded along its full run.
Repipe
Multiple leaks, old pipe material throughout, or house-wide water quality issues.
Full replacement of the supply system with PEX or copper. The permanent solution when the pipe is the problem, not just a single leak.
Don't break concrete on a guess.
We pinpoint the leak first with pressure testing and acoustic listening. Then we walk you through the repair options with a written price before any work begins.

Questions Homeowners Ask
What are the signs of a slab leak?
Warm spots on the floor, the sound of running water when everything is off, an unexplained jump in your water bill, cracks in flooring, or a water meter that spins with all fixtures closed. Any one of these is worth a pressure test.
How do you find a slab leak without breaking concrete?
We isolate and pressure-test the lines to confirm the leak, then pinpoint it with acoustic listening equipment. Concrete only comes up after we know exactly where — never on a guess.
Does homeowners insurance cover slab leaks?
Many policies cover the resulting water damage and the access (tearing out and repairing the floor), though often not the pipe repair itself. We provide the detailed diagnostic report and itemized invoice your adjuster needs.
Spot repair, reroute, or repipe — which do I need?
It depends on the pipe material, the age of the system, and whether this is the first leak or the third. A single pinhole in otherwise sound copper may justify a spot fix; repeated leaks usually mean a reroute or repipe saves money long-term. We walk you through the math on all three.
Why are slab leaks so common in the Hill Country?
Expansive clay soils shift with wet-dry cycles and stress the pipes under the slab, and our aggressive hard water eats at copper from the inside. The combination makes slab leaks a routine call in this area.
How long does a slab leak repair take?
Detection is usually done in a single visit. A spot repair often takes a day; a reroute typically one to two days. You get a written price and timeline before any work begins.
