Sample job
Got a call last month from a the south San Jose home — 1970s build. Symptom: a warm spot in the master bedroom carpet, plus a $140 jump in the water bill. Cause: pinhole leak in the hot-water copper line under the slab. Re-routed the line overhead through the attic and abandoned the slab line, all done in under 90 minutes, billed flat-rate at $2275.
Scope of work
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.
