Slab Leak Detection & Repair services in Philadelphia
Our crew runs about half of its weekly volume on slab leak detection & repair calls in and around Philadelphia. The other half is everything else local-service. So yes, we know your area. Three things you can count on: we show up when we say we will, we quote before we work, and we don't pad the bill.
Local context for Philadelphia
If you're inside the city limits, we're typically there inside an hour during business hours. Outside the metro, plan on a bit longer.
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
Property manager call, Philadelphia-area duplex. Both units had a warm spot in the master bedroom carpet, plus a $140 jump in the water bill. We pulled the system apart and found pinhole leak in the hot-water copper line under the slab. Re-routed the line overhead through the attic and abandoned the slab line on the same trip — both tenants happy. $685.
