Slab Leak Detection & Repair in the Las Vegas Valley

Slab leak detection and repair covers finding and fixing a leak in supply pipe under a concrete floor. Detection uses electronic and acoustic equipment to pinpoint the leak through the slab. The repair is either a spot repair, where a small section of concrete is opened directly over the leak, or a reroute, where a new line is run through walls or the attic and the leaking section under the slab is taken out of service.

Slab leaks are hidden by design. The pipe sits under concrete, so the first signs are indirect: a warm patch on tile when a hot line is leaking, a water bill that keeps climbing, the sound of running water with everything off, a water heater that never seems to rest, or flooring that lifts or smells damp. In the Las Vegas Valley, where most homes are built slab-on-grade, the usual causes are aging copper developing pinholes, scale and wear from very hard water over many years, and buried lines abraded where they run through caliche or stressed where poorly compacted fill has settled.

We start by locating the leak precisely with electronic and acoustic equipment, and we confirm whether it is on the hot or cold side. Only then does the repair decision make sense. A single leak in an accessible spot on otherwise sound pipe is often a spot repair through a small opening in the slab. Where the pipe is old enough that more leaks are likely, or the leak sits under cabinets or a wall, rerouting the line overhead avoids breaking the floor and replaces the problem section in one job. We lay out both with a written price before work starts.

If several lines are failing, a Whole-House Repipe may be the better answer, and Electronic Leak Detection can check the rest of the system. Call (702) 438-3357 to book slab leak detection.

Pinhole leaks in aging copper supply lines under the slab. Scale and internal wear from very hard water over many years. Pipe abraded where it runs through caliche. Lines pulled out of grade where poorly compacted fill or expansive clay has moved beneath the slab. Failed joints or fittings on older under-slab runs. Hot water lines leaking and keeping the water heater running.

Slab leak detection in the Las Vegas Valley typically runs $150 to $300 while slab leak repair typically runs $500 to $3,000. These are typical valley ranges, not a quote. Repair cost depends on where the leak is, whether it is a spot repair or a reroute, the length of any reroute, and what flooring or concrete sits over the leak. Caliche can make any excavation slower and more costly. We can give a general idea on the phone, and you get a written price on site before work starts. Detection is usually a single visit, and many spot repairs and short reroutes are completed in one to two days.

Leaks are located with electronic and acoustic detection after the system is isolated to confirm the loss and identify the hot or cold side. Spot repairs open a small section of slab over the leak, replace the failed section with code-approved pipe, and the concrete is patched once the repair is tested. Reroutes run new PEX or copper through walls or the attic and take the leaking under-slab section out of service. Every repair is pressure tested before the job is closed.

If you notice a warm floor, a moving meter with everything off, or a sudden jump in the water bill, close the main shutoff if water is coming up through the floor. Note where the warm or damp areas are. Then call Active Plumbing at (702) 438-3357 to book slab leak detection, or for 24/7 help with an active leak.
