Slab Leak Detection & Repair
Nearly every home around Rockwall sits on a slab-on-grade foundation, which means the water supply lines run through or beneath the concrete. When one fails, the water has nowhere visible to go — it moves sideways through soil, up through the slab, or down and away.
That is what makes slab leaks expensive. Not the repair itself, but the weeks or months a homeowner runs one before anything obvious happens. The signs are there early. They are just quiet.
The other reason they get expensive is bad process. A slab leak should be pinpointed with electronic detection and pressure isolation before a single inch of concrete comes up. If someone proposes opening the floor to go find it, get a second opinion.
When you need slab leaks
The symptoms homeowners actually describe when they call us — and what each one usually means.
A warm patch on the floor
Heated water pooling under concrete conducts straight up. Tile or laminate noticeably warmer than the floor around it, in a spot with no vent and no sun, is close to diagnostic. Pets usually find it before people do.
Water bill climbs and holds
The first real clue in most cases, and the one people talk themselves out of. Water under a slab is water you are paying for, every hour.
Running water with the house silent
Late at night, everything off, a faint continuous hiss near the floor. It often reads as coming from inside a wall, because the sound travels along the pipe.
Hot water that never recovers
A hot-side slab leak has your water heater constantly reheating water that is leaving the system. Homeowners frequently replace the heater first. The new one behaves the same.
Flooring, grout and doors going wrong
Damp carpet with no spill, wood cupping in one area, new cracks in tile grout, a musty smell that will not clear. Later still: doors that suddenly stick, and cracks in the foundation as soil washes out beneath it.
What actually happens on the job
No mystery, no vague diagnosis. Here is the sequence we follow every time.
Rule out the cheaper problems first
Pressure testing hot and cold separately frequently reveals a running toilet, an irrigation valve or a failed pressure regulator instead. We would rather find one of those.
Pinpoint acoustically and thermally
Acoustic listening equipment traces the sound of escaping water through the slab; thermal imaging maps hot-side leaks from above. Together they usually mark a specific area rather than a general region of the house.
Lay out the three real options
Spot repair, reroute, or repipe. Which one is right depends on pipe condition, leak location, and whether this is your first leak or your third. You get the reasoning, not just a recommendation.
Repair with the smallest footprint possible
If concrete comes up, it is a targeted opening at a known location, patched properly afterward. In plenty of cases a reroute means no concrete work at all.
Why slab leaks are a North Texas specialty
Two things work against us. Our water is hard, and over years the mineral content combined with pinhole corrosion eats copper supply lines from the inside out. And our soil is expansive clay — it swells when wet and shrinks hard through a long dry summer, which flexes the slab and everything cast into it. Add a hard freeze every couple of winters and any weak joint eventually finds its limit. This is not a reflection on how your home was built. It is what happens to buried lines in this part of Texas, and it is why we see slab leaks concentrated in neighborhoods of a certain age rather than scattered at random.
Straight talk on pricing
Cost varies more on slab leaks than on almost any other plumbing job, and it depends on real things: hot side or cold side, how deep the slab is, whether the location sits under tile or under a kitchen island, and which of the three repair approaches makes sense. Any number quoted before the leak is located is guesswork. We give you a firm price once we know what we are dealing with, and we will tell you plainly when a reroute is cheaper than the spot repair.
(469) 338-5533Slab Leaks questions we get asked
Can a slab leak damage my foundation?
It can, and that is the real argument against waiting. Water running under the slab washes out supporting soil and keeps the surrounding clay saturated, which makes it swell unevenly. Over time that shows up as foundation cracks, sticking doors and separating trim. Caught early, a slab leak is a plumbing repair. Left long enough it becomes a foundation conversation.
Is a reroute better than repairing the pipe under the slab?
Often, yes. A reroute abandons the failed run and puts new pipe where it can be inspected and repaired later without touching concrete. It makes most sense when the pipe is older, when the leak sits somewhere difficult, or when you have already had a leak in the same system. A spot repair is the better call when the plumbing is otherwise sound and access is straightforward.
How long can I wait?
You should not. A slab leak does not heal and it does not hold steady — it erodes soil under your foundation continuously. Every week it runs adds to both the water bill and the eventual damage. If the meter test confirms water is leaving the system, treat it as active.
Will homeowners insurance pay for it?
Frequently they cover the access — breaking and replacing concrete, flooring, drywall — while excluding the pipe itself and anything classified as gradual. Call your carrier before work begins, photograph everything, and make sure the invoice separates access from repair clearly enough for an adjuster to read.
