Slab Leak Repair in Highland Village, TX
Water pooling on tile you never spilled on. A hot spot on a bedroom floor. Water bill that jumped $80 with nothing new turned on. We pinpoint slab leaks under Highland Village condos, townhomes, and ranches before anything gets torn up — and quote the reroute honestly against the spot repair.
The Right Question is Reroute or Repair — Not "Where Do We Break the Slab?"
Highland Village's housing stock is dense and old for a North Dallas suburb — a lot of the ranches off Valley View were plumbed in the 1970s with Type M copper on top of a slab that was poured before post-tensioning was standard. Forty years of Blackland Prairie clay heaving under that slab, plus DWU's chloramine chewing on the copper from the inside, is why slab leaks are our most common Highland Village call.
The condos around Brookhaven and the townhomes in Valwood Park are different — newer copper or PEX, but with shared walls and finished concrete floors where every square foot of tear-out is expensive to put back. Pinpointing the exact leak matters even more here, because the wrong guess doubles the restoration bill.
Either way, the right first call is not to a plumber with a jackhammer. It is to somebody with acoustic and thermal gear who can put an X on the slab within a few inches, and then walk you through whether it makes more sense to open the concrete or bypass the failed line entirely with an overhead PEX reroute.
Signs of a Slab Leak in Your Highland Village Home
A slab leak wastes water for weeks before it becomes obvious. Catching it early is a $600 reroute. Missing it is a $6,000 flooring and mold remediation.
A hot-water slab leak heats the concrete directly above it. Walk your home barefoot in the morning — a suspicious warm patch on tile or wood is almost always a compromised hot-side line.
A pinhole slab leak wastes 60 to 300 gallons a day silently. If your Highland Village bill jumped $40 to $150 with nothing new plugged in, a slab leak is the most common cause.
If a hot-side slab line is bleeding, your water heater refires constantly to keep up. You will hear it or feel the closet warmer than usual.
Long-term slab moisture makes grout lines fail and hardwood cup upward at the seams. Both are late-stage signs — the leak has already been running for months.
Shut every fixture in the home, put your ear to the slab or a wall, and if you hear a faint hiss or trickle, that is water under the concrete.
A slab leak on the hot line drops shower pressure and shortens shower duration. If the cold side is fine but the hot side is weak, look under the slab first.
Locate First, Then Choose the Right Fix
We are not opening your slab until we know exactly where the leak is and whether cutting concrete is even the right call.
- 1Isolate hot vs cold
We pressure-test both sides at the water heater to confirm which line is leaking. That decides where we spend detection time and whether the reroute would need one line or two.
- 2Acoustic and thermal locate
Ground microphones on the floor, thermal camera on the walls and slab, and a hydrogen tracer on the isolated line. Between the three we usually put the leak inside a 12-inch circle.
- 3Walk you through the two paths honestly
Spot repair means one small slab cut, one splice, and concrete patch — cheapest if the rest of the line is healthy. Reroute means running a new PEX line overhead through the attic and abandoning the slab run — better if the rest of the line is the same age and material.
- 4Execute the chosen fix
If spot repair, we saw-cut concrete cleanly, expose the leak, replace the failed section with a compression-fit splice or hard sweat, and patch. If reroute, we run PEX-A through the attic, tie in above the fixtures, and cap the slab line.
- 5Pressure test and document
We hold 100 PSI on the finished line for 15 minutes with you watching the gauge. You get before-and-after photos of the detection, the repair, and the pressure test — you know exactly what you paid for.
Spot Repair or Reroute — We Quote Both
There is no universal right answer. The right answer depends on the age of your copper, how many bathrooms are on that line, and how finished your slab is.
We saw-cut a small opening in the concrete, expose the exact leak, splice in a new fitting, patch the concrete. Best for isolated failures on lines that are otherwise still in good shape.
- Cheapest for a first-time isolated failure
- Preserves original supply routing
- Concrete patch and finish flooring are on your restoration crew
- Not a great choice if the rest of your copper is the same age
We abandon the failed slab run, route a new PEX-A line overhead through the attic, tie in above the fixtures. Best when the failed section is likely the first of several on an aging system.
- No more concrete cuts on that line, ever
- Bypasses corroding copper you cannot inspect
- Cleaner install for finished basements/no-attic condos means running in soffits
- Slightly higher up-front, much cheaper over 10 years
What We See in Each Part of Highland Village
Different construction eras, different slab-leak realities.
Lakefront custom homes with long private lateral runs and older copper repiped to PEX. Slab leaks are our most common Highland Shores call.
Newer construction with PEX manifolds. Failures cluster at manifold connections and outdoor freeze-splits on hose bibs.
1990s builds with original copper under slab. Pinhole leaks near the water heater riser are the pattern.
Mature trees mean root intrusion at clay tie-ins near the meter. Annual maintenance jets keep it under control.
Two-story custom homes with upstairs laundry. Failed washer-box valves and long PEX runs to the third bath are the calls.
Cul-de-sac homes on the water. Deep lateral runs and shifting shoreline soil make sewer failures common.
What Highland Village Homeowners Say
Slab Leak, Fixed Right the First Time
Every Highland Village slab leak we repair carries a written workmanship guarantee — one year on spot repairs, five years on full reroutes. If the fix fails on our workmanship, we make it right at no charge. If the leak comes back somewhere else on the same aging copper, we told you at quote time and it is why we suggested the reroute.
Fully licensed by the Texas State Board of Plumbing Examiners, insured and bonded, and dispatching from nearby Frisco and The Colony — most Highland Village addresses see a truck the same afternoon on an active slab leak, faster if you are actively losing water.
