From the books — a recent Seattle job
Got a call last month from a the north Seattle home — 1970s build. Symptom: mildew smell along the baseboard. Cause: slow cold-water slab leak under the kitchen. Re-routed the cold line and dried the slab, all done in before lunch, billed flat-rate at $1025.
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 have two repair options.
