A section of tile that feels noticeably warmer than the rest of the room. Beads of water forming near a baseboard for no reason you can point to. A water bill that spiked and never came back down. Our job is finding exactly where a Richardson slab is leaking before touching any concrete, then laying out honestly whether a direct patch or a rerouted line overhead makes more sense for that particular pipe.
Much of Richardson's original housing stock, including the Heights Park area, dates to the postwar decades when builders ran copper supply piping directly into the slab, well before post-tensioned foundations became standard practice. Beneath those older slabs sits Blackland Prairie clay, ground that expands after rain and pulls back tight through dry stretches, and that endless flexing puts real stress on rigid copper that has nowhere to give.
The water moving through those pipes carries its own wear factor. Supply in Richardson comes wholesale through the North Texas Municipal Water District and tests hard, near 18 grains per gallon, with chloramine as the disinfectant for most of the year. None of that alone creates a leak, but combined with decades of clay movement, it steadily thins copper from the inside until a pinhole finally opens.
None of that matters until the exact leak location is confirmed. Listening equipment and thermal cameras let us mark the spot to within a small area, and only once that is settled does it make sense to weigh a small concrete opening against running a fresh line overhead instead.

A slab leak can go unnoticed for a long stretch. Finding it early keeps the fix small and the flooring intact.
Hot water escaping under the slab heats the concrete directly above it. Walking the house barefoot early in the day is often the quickest way to notice a section of tile or wood running warmer than everywhere else.
A pinhole under the slab can run quietly for a long stretch. A City of Richardson bill that jumped with no new appliance or fixture running belongs near the top of the list of possible causes.
When a hot-side line under the slab is losing water, the heater works overtime trying to keep up. You might hear it kick on more frequently or feel extra heat coming from its closet.
Moisture trapped under a slab for months eventually shows up as failing grout or hardwood planks that cup upward. Both point to a leak that has already been active for some time.
Shut off every fixture in the house, then listen closely near the floor or a nearby wall. A quiet hiss or trickle under those conditions usually means water moving somewhere beneath the concrete.
A leaking hot line under the slab can quietly rob pressure and cut hot water short while the cold side behaves normally. That one-sided pattern is a useful clue about which line to check first.
No concrete gets opened until we know precisely where the leak sits and whether opening concrete is even necessary.
We isolate each side at the water heater to see which one is losing pressure. That reading alone tells us where to focus detection time and whether a bypass line, if needed, would involve one run or two.
Ground microphones pick up sound through the slab, a thermal camera reads temperature differences in the floor and walls, and tracer gas backs up either reading on a tough locate. Together they usually box the leak into a tight area.
A direct patch opens one small section of slab, splices in a repair at the exact failure point, and closes the concrete back up — the simpler route when the surrounding pipe is otherwise sound. An overhead bypass retires the buried section entirely and runs new supply line through the attic instead — a stronger call when the rest of that copper run is the same age and likely next in line to fail.
For a direct patch, we cut a clean opening, expose the failed section, splice in new copper, and patch the floor. For an overhead bypass, we run fresh line through the attic, connect it above the fixtures it serves, and permanently cap the old slab section.
We hold pressure on the completed line while you watch the gauge yourself, then leave you with photos covering the detection, the repair, and the final test — a plain record of what happened and why.
No single answer fits every house. It comes down to how old your copper is, how many bathrooms share that particular line, and how expensive your slab flooring is to disturb.
We cut one small opening in the slab, expose the failed spot precisely, splice in a repair, and close the concrete back up. A sensible choice when the surrounding copper still has plenty of life left.
We retire the failed slab section for good, run new supply line through the attic, and tie it in above the fixtures it feeds. The stronger option when today's failure is likely the first of several still to come on aging pipe.
Construction era and original pipe material shape where and how a slab leak shows up.
Built mostly from the late 1940s through the 1960s with copper poured directly into the slab, Heights Park homes have absorbed decades of Blackland Prairie clay movement underneath, leaving many of these homes exposed to a slab leak eventually.
Mid-century houses sit close to newer builds near the University of Texas at Dallas in Canyon Creek, so the age and condition of slab copper can vary sharply from one house to its neighbor.
Prairie Creek's homes trace to the 1960s alongside the park bordering the neighborhood, which puts the original slab-poured copper in roughly the same aging window as much of Richardson's older core.
The more affordable, older housing on Richardson's west side typically still carries its original copper, so an unexplained warm spot on the floor there deserves a look sooner rather than later.
Addresses along Belt Line Road pass through several of the city's older platted sections, where slab-poured copper from the postwar building years is old enough that an early detection check is worth scheduling.
Homes near Duck Creek Linear Park date to Richardson's mid-century growth period, putting their slab-poured copper in the same aging bracket as much of the older city core.

Every slab leak repair we finish carries warrantied labor on our end. If our workmanship fails, we return and correct it at no charge. If a separate section of the same aging copper develops its own leak down the road, that is precisely the scenario we would have flagged at quote time as a reason to weigh the bypass option instead.
Aqua Pure Plumbing is licensed through the Texas State Board of Plumbing Examiners, insured, and family-owned, with every truck dispatching from our shop in The Colony. A typical Richardson address is roughly 30 to 40 minutes out under normal traffic, and we book same-day visits every day of the week, from morning until early evening.
A slab leak often means the rest of a home's supply lines are reaching the same age. We can talk through sewer, water heater, and whole-house repiping in the same visit, right here in Richardson.
