One we ran last year
Recent Raleigh job: mildew smell along the baseboard in a 1960s home. We re-routed the cold line and dried the slab after diagnosing slow cold-water slab leak under the kitchen. Cost ran $1674 — pretty middle-of-the-road for that fix.
The actual 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 have 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.
