A recent slab leak detection & repair call
Last spring we got a call from a homeowner near the north Austin. A warm spot in the master bedroom carpet, plus a $140 jump in the water bill. Diagnosis: pinhole leak in the hot-water copper line under the slab. We re-routed the line overhead through the attic and abandoned the slab line, ran the test, and were out the door in in one trip. Total: $496 including parts.
What's typical for this job
Slab leaks are pinhole leaks in copper plumbing lines that run inside or under a concrete slab foundation. Common in 1960s through 1980s slab-on-grade builds across the Sun Belt and parts of the Midwest.
Signs: warm or wet spots on the floor, unexplained jumps in the water bill, the sound of running water when nothing is on, mildew smell along baseboards. Hot-side leaks show up faster than cold-side because of the warm spot.
Detection runs $280–$480 standalone. We use acoustic listening equipment plus an infrared thermal camera. Once we've located it, you've two repair options.
Option A: re-route the failed line through the attic or crawl space, abandoning the line in the slab. Cost: $1,400–$2,800. Faster, no jackhammer, and future-proofs against the next pinhole on that line.
