Slab Leak Detection & Repair in Georgetown, TX

What a slab leak feels like before you ever see water

It almost never starts with a puddle. A warm patch turns up on a tile floor in a Wolf Ranch kitchen, or a spot on the carpet stays faintly damp no matter what. Some people hear a soft rush of water at night with every faucet off. Others just watch the bill climb for no reason they can name.

Those are the early tells of a line leaking beneath the slab. Because the pipe runs under several inches of concrete, the water has to find its own way out, and by the time it surfaces it has often been running for weeks. Catching it at the warm-floor stage is far cheaper than catching it once the flooring lifts.

If you notice any of that, the smart move is to shut off irrigation and run the meter test. A meter that keeps creeping with everything closed points to a live leak, and a slab line is one of the most common places it hides.

How we find it under the concrete

We work from the least invasive tools up. Electronic acoustic sensors let us listen for the high hiss a pressurized line makes as water escapes, even through a foundation. Thermal cameras read the warmth a hot-water leak spreads under the floor, which narrows the search to a few feet.

From there we isolate the system and run a pressure test to confirm whether the leak sits on the supply side or the drain side. If it is a drain line, we can introduce tracer gas that rises through the slab at the exact break. The point of all of it is simple. We do not open concrete to look for the leak. We open concrete only after we already know where it is.

How we repair it once the spot is known

Sometimes the fix is a small access cut directly over the leak, a clean spot repair, and a patch. Other times the better answer is a reroute, where we abandon the failed line under the slab and run a fresh line through the wall or attic instead. That avoids reopening the same spot a year later if the rest of the pipe is the same age.

On older homes with copper that has been sitting in hard water for decades, a single pinhole is often a sign more are coming, and a reroute or partial repipe saves you repeat visits. We walk you through the trade-offs in plain words and let you decide. There is no upsell script here.

Why Georgetown slabs leak the way they do

Georgetown sits on the edge of the Hill Country, where thin caliche soil covers limestone bedrock. That ground does not swell and shrink the way deep clay does, but it still moves during the region's swing from drought to heavy rain, and that movement stresses the rigid lines cast into a slab. Newer builds in Wolf Ranch and Rancho Sienna lean on flexible PEX, which handles that better, while older copper is far less forgiving.

The water matters too. At roughly 25.8 grains per gallon, Georgetown's supply is among the hardest in Texas, and that mineral load corrodes copper from the inside until it fails. Put a moving slab and very-hard water together and you get the pattern we see across the city.

Across Georgetown, from old slabs to new

Slab leaks turn up across the whole city, but they wear different faces. In the established 78626 core, older slabs paired with aging copper give us classic hot-line leaks under the floor. Out in the 78628 and 78633 growth areas, newer slabs with PEX leak less often, and when they do it tends to be at a fitting or a penetration rather than a corroded run. We adjust the search to the age of the home, because a 1990s slab and a 2020s slab rarely hand us the same clue first.

Whatever the vintage, the principle does not change. We confirm the leak is real, pin it to a spot, and repair only what needs repairing.
