Slab Leak Repair in Midland, TX
A warm spot on the floor. A water meter that won't stop spinning. The faint hiss of running water behind a wall. Those are slab leak signatures — and in Midland's caliche and clay, they're more common than almost anywhere else in Texas. We locate the leak precisely and repair it with minimal tear-out.
Signs you may have a slab leak
Water lines under your foundation don't announce themselves directly — they leak quietly into soil and slab for weeks before showing symptoms. Any one of these is worth a prompt call:
- Warm or hot spots on the floor (usually a leaking hot-water line)
- The water meter moving with every fixture and appliance turned off
- The sound of running water when nothing is on
- New cracks in tile, drywall, or along the slab edge
- Musty smell or mold that keeps coming back
- A water bill that jumped with no change in usage
Catching it early matters. Water traveling under a slab erodes soil, undermines the foundation, and turns a pipe repair into a foundation problem.
Why Midland slabs leak more than most
Midland sits on caliche and expansive clay — soils that shift significantly as they wet and dry. On top of that, this is a boom town: the U.S. Census Bureau's Vintage 2025 estimates put Midland's population at 147,615, up roughly 11% since 2020, making it the fastest-growing larger city in West Texas. Homes thrown up during boom years — and there have been several cycles — were slabbed fast on ground that never stopped moving.
The result is predictable: copper lines under slabs rub, kink, and fatigue as the foundation flexes, and boom-era polybutylene lines reach the end of their working life. Settlement also creates sewer bellies and low spots where drains hold water and fail. This is ground-level stuff that out-of-town plumbers miss; we diagnose the soil problem, not just the symptom.
How we find the leak before we cut
The goal is one small opening, not a jackhammer marathon. We start with the free clues: a meter-isolation test with everything off, then zone-by-zone pressure testing to narrow the leak to a specific line. From there, thermal imaging and acoustic listening equipment pinpoint the failure under the slab. Most leaks get located to within a foot or two before any concrete is touched.
Repair options, from least invasive up
- Spot repair — open a small section of slab, repair the failed fitting or section of pipe, and put everything back. Right answer for a single, recent failure on otherwise healthy lines.
- Reroute — abandon the failed under-slab line and run new piping overhead through the attic. Common in Texas, and often smarter than repeated slab cuts when soil movement is active.
- Partial or whole-house repiping — when failures repeat in boom-era polybutylene or corroded lines, repiping to PEX or copper ends the cycle for good.
Documentation for insurance — and your buyer
We photograph the locate, the repair, and the finished work, and provide a written summary with moisture readings. Many homeowner policies cover leak detection and the pipe repair itself; the documentation helps. Out-of-state owners get everything texted the same day — standard practice for us, and a nice record to hand a future buyer.
Slab leaks don't fix themselves
Left alone, an under-slab leak keeps eroding soil and can crack the foundation it sits under. If a hot-water line is the culprit, you're also paying to heat water that leaks into the ground 24/7 — which shows up on both your water and gas bills. If the same home has an aging water heater working overtime to feed the leak, that's worth checking too.
