Leak Detection & Repair in Round Rock, TX

Round Rock sits on some of the harder water in Central Texas. Since June 2020 the city's main supply has flowed from Lake Travis through the BCRUA partnership, testing near 15.2 grains per gallon. That heavy mineral load builds scale inside copper supply lines and gnaws at the metal from within. Give it enough years and you get the pinhole failures that surface behind drywall and beneath slabs, usually in the aging copper around town.

The ground fights the pipes too, and this town is unusual because it straddles two soil zones. The west half rests on Hill Country limestone, a porous karst that lets a leak travel sideways and emerge far from where it began. The east half leans into Blackland Prairie clay, which swells after rain and shrinks hard during drought. That constant motion tugs on slab plumbing and sewer laterals until a joint separates. Which half of town your house sits on changes how we hunt the source, so we ask up front.

Age is the third strike. Houses in Forest Creek, Brushy Creek, and Cat Hollow rose in the late 1980s and 1990s, right after Dell planted its headquarters here. Their original copper now runs thirty to forty years old, squarely inside the window where pinholes begin. Newer builds out in Teravista, Paloma Lake, and Mayfield Ranch rely on PEX, which shrugs off mineral buildup better yet still fails at fittings and joints. Old Town holds the oldest stock of all, where galvanized supply and cast iron drains rust and split as the decades pass.

Weather sets the clock. Central Texas swings between deep drought and sudden cloudbursts, and the city falls inside what locals call Flash Flood Alley, where limestone funnels storm runoff straight into Brushy Creek. When a long dry spell breaks, the eastern clay rehydrates and heaves, and that jolt is often what finishes a slab line already under strain. Service calls cluster after the first heavy rain following a drought, and the dry spring of 2026 keeps that pattern alive.

A hidden leak does not have to mean a wall you tear out. We begin with detection. Acoustic sensors listen for the hiss of pressurized water escaping a pipe. Thermal cameras read the faint temperature shift a leak leaves on a floor or wall. Electronic tracing and pressure testing map the run and narrow the spot. By the time we cut, we already know where.

On the limestone west side that patience pays off, since water there can emerge yards from the actual break. Chasing the wet patch alone would mean opening the wrong place. We trace the pipe instead. When the repair calls for it, a spot fix, a reroute, or a trenchless pull can solve the trouble without a full excavation. If you would rather talk it through first, call (512) 737-6168 and describe what you notice.

Different faults call for different tools, and we bring the ones that fit the job. Acoustic gear works well on pressurized supply lines under a slab. Thermal imaging shines on hot-water seeps and drips behind drywall. A camera runs the sewer line when the trouble is a drain or a lateral. Tracer gas and line tracing handle the breaks that hide from sound, like a slow weep through dry, rocky ground. Matching the method to the fault is most of the work, and it explains why a careful locate beats guessing every time.

Leak work makes people nervous about the bill, and we understand why. We do not quote a flat figure sight unseen, because an honest number depends on the kind of leak and how hard it is to reach. A slab line under a hallway and a dripping hose bib at the side of the house are not the same job. What we promise instead is a clear breakdown before any digging starts: what we found, the ways to fix it, and the price of each path. You choose from there, with no push toward work you do not need.

We also will not manufacture urgency. If a small drip can wait until morning, we say so plainly. If it cannot, we explain the reason. That kind of straight talk is rare in this trade, and earning that reputation in Round Rock matters more to us than padding an invoice.
