Slab Leak Detection & Repair in Phoenix, AZ
Honestly, most slab leak detection & repair questions can be answered over the phone. Save yourself the dispatch fee — call first, ask second. We work clean, leave the area better than we found it, and stick around to test the repair before we drive off.
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.

One we ran last year
