Leak Detection & Slab Leak Repair in Austin

Texas slab foundations and copper pipes in shifting black clay are a bad marriage — and Austin's water pressure regulators age out like everything else. If your meter spins with everything off, you don't need guesswork. You need someone to find it without jackhammering your floor "to check."

The Classic Austin Warning Signs

• An Austin Water bill that jumped $100+ with no change in habits (tiered rates make leaks expensive fast)
• Warm or hot spots on the floor — hot-side slab leak under your feet
• The low-flow indicator (small triangle/dial) on your water meter moving when everything's off
• Foundation cracks growing, doors sticking, or the smell of damp drywall
• Sound of running water in walls at night

How We Find Leaks Without Demolition

We isolate the system, pressure-test hot vs. cold vs. yard lines, then locate with acoustic listening equipment and thermal imaging. On a clean slab leak we typically narrow the dig to a single tile or a small section of foundation — not exploratory trenching. The $250–$450 detection visit produces a written report, photos, and a fixed repair quote. Spot repairs under slab run $1,200–$3,500 depending on access and pipe condition; if the line is old enough that one leak means three more, we'll show you reroute options (often cheaper than repeated slab digs).

Don't Forget the PRV

Austin's municipal pressure runs high in many neighborhoods, and the pressure-reducing valve (PRV) at your meter protects every fixture in the house. A failed PRV shows up as banging pipes, dripping T&P valves, and premature appliance death. PRV replacement is $350–$650 installed — and it's the cheapest insurance against the next slab leak.
