Slab Leak Detection & Repair in Henderson, NV

The Henderson slab leak recipe

Nearly every Henderson home sits on a concrete slab-on-grade — many post-tensioned, especially in newer master-planned communities — with copper supply lines embedded in or running beneath the concrete. Three local factors combine against those pipes. The ground: caliche, a cemented calcium-carbonate layer common across the valley, plus pockets of expansive desert clay that swell when they get wet and shrink when they dry. Water a foundation zone, and that clay moves — grinding pipes against concrete and caliche for years. The water: at typically 304 mg/L (18 grains per gallon), Henderson's supply pits copper from the inside. And the heat: thermal expansion stresses runs that were already working hard.

The result is a leak you can't see, quietly undermining your slab, raising your water bill, and — if it's hot-side — warming your floor. Left alone, it can heave the slab, breed mold under flooring, and turn a $2,000 reroute into a foundation conversation. The good news: detected early, most slab leaks are a one-day fix.

How detection-first works

We start with electronic detection — acoustic listening, thermal imaging, and pressure isolation to split hot from cold lines. On post-tension slabs (common in Inspirada, Cadence, Seven Hills, and most 1990s+ Henderson builds), we locate tension tendons before any core drilling; hitting one is a structural problem, not a plumbing one, and it's why handymen and out-of-town franchises make expensive mistakes here. Once located, you choose the fix: a spot repair through the slab, or a reroute through the attic or walls — often the smarter long-term play in homes where the same pipe is likely to fail again nearby.

Signs you may have a slab leak

• Water bill jumped with no change in usage
• Warm or damp spots on floors; buckling laminate or tile
• Sound of running water when everything is off
• Cracks in tile, drywall, or the slab edge that appear suddenly
• Water pooling at the foundation or a constantly damp spot in the yard
• Low water pressure throughout the house
