Locating Water Lines That Leak Beneath a Lavon Slab
Why Young Slabs in Lavon Still Spring Leaks
Most of Lavon went vertical in the last two decades, so houses in Grand Heritage, Elevon, LakePointe and Bear Creek sit on relatively young slab on grade foundations. New concrete is no guarantee against a slab leak. The Blackland Prairie clay under this stretch of Collin County swells through a wet spring and shrinks back hard in an August drought, and that seasonal movement pulls on copper and PEX lines cast into or run beneath the pour. A pipe nicked during the original build, an abrasion where a line crosses rebar, or a fitting worked loose by soil heave can weep for months before anyone notices. Warm tile underfoot, a floor that stays damp, or a water bill that climbs while nothing changed indoors usually starts the conversation.
Listening, Tracing and Thermal Imaging
Finding water under four inches of concrete is a listening job long before it becomes a repair job. We isolate the house at the meter and watch the dial, then pressure test the hot and cold sides separately so we know which loop is losing water. Ground microphones amplify the hiss of pressurized water escaping into gravel and clay, while line tracing maps the real route of the pipe instead of the route drawn on a builder plan. Thermal imaging reads the heat signature of a hot water line through flooring. Using those tools together, we can mark a spot on your floor off Highway 78 and stand behind that mark, so nobody opens concrete on a hunch.
Turning a Located Leak Into a Plan
A detection visit in Lavon should end with a decision, not a shrug. Depending on where the leak sits, the realistic choices are a spot repair through a small opening in the slab, rerouting that single run overhead through the attic, or repiping the house when the same line has failed more than once. We explain what each option means for your flooring, your schedule, and any builder or home warranty paperwork you may need to file.
