Leak Detection & Slab Leak Repair in Austin, TX

Those suburbs, and most of the east side of the Austin metro, are built on expansive clay. The clay absorbs water and swells during a wet spring, then dries and shrinks through a Central Texas summer, and a slab foundation moves with it. Copper lines run under or through the slab were not designed for that cycle, and over twenty or thirty years a joint fatigues or a line wears through where it rubs on the concrete. Houses from the 1980s and 1990s are now at that age. A leak feeds more water into the clay, the slab moves more, and the problem compounds, which is why an early call matters more here than in most places.

Not always, and never without showing you why first. Once the leak is located, there are usually three options: open the slab at the marked spot and repair the section, abandon that line and reroute a new one through the attic or walls, or repipe the house if the lines are old enough that the next leak is inevitable. For a single leak in a newer home, a spot repair is often right. For an older Austin home on its second or third slab leak, a reroute or repipe usually costs less over the next five years. We price the options side by side and you choose.

Turn off every fixture and appliance that uses water, including ice makers and irrigation, then look at your water meter at the curb. Most Austin-area meters have a small low-flow indicator that spins when any water is moving. If it turns with everything off, water is leaving somewhere on your side of the meter. You can narrow it further by closing the main shutoff at the house: if the meter stops, the leak is in the yard line; if it keeps moving, it is inside or under the house. That ten-minute check is worth doing before you call, and it tells us where to start.

Policies vary, and we are plumbers rather than insurance agents, so read yours or call your agent. As a general pattern, many Texas policies cover the sudden water damage a leak causes and the cost of accessing the pipe, while the pipe repair itself and gradual damage may be excluded. What helps a claim in every case is documentation: the leak location report, photos and an itemized written quote, all of which we provide as part of the job. If the repair runs larger than expected, financing through Service Finance Company is available, subject to credit approval.

After the leak is located, a direct repair runs in order. Water off, then access: in 1980s and 90s slab homes in Round Rock, Pflugerville and Kyle, that means lifting flooring over the marked spot and opening a small section of concrete, or tunneling in from outside near an exterior wall. We expose the copper, cut out the failed section, splice in new pipe with proper fittings and pressure-test at full house pressure before anything is closed. Soil is compacted back, concrete patched flush, and finished flooring restored afterward.

Because Blackland clay keeps moving, we check the whole exposed run, not just the pinhole. Slab leak repair in Austin is priced in writing and backed by the Home Comfort Guarantee; our Austin plumbers handle the permit if one applies.

It matters, and the pressure test tells us early. Hot-side slab leaks are the common ones in Austin; hard water and heat work on copper together, and the hot line typically runs from a water heater in the attic or garage to the kitchen and baths. That makes rerouting it overhead simple: new line through the attic the heater already sits in, down a wall at each fixture, and the old run abandoned for good. For a second hot-side leak, we lean that way.

Cold lines enter at the slab edge and branch to more fixtures, so a reroute is a bigger project. A single cold-side leak near an exterior wall is often a clean direct repair instead. Slab leak repair in Austin gets both prices in writing so the choice is yours.
