Slab Leak Detection & Repair in Minneapolis, MN
There's a reason slab leak detection & repair in Minneapolis is mostly handled by small shops, not the big franchises: nobody beats a guy who knows the housing stock and answers his phone. Most of our work comes from neighbors of past customers. That's the only marketing we trust.

Local context for Minneapolis
Climate and housing age in Minneapolis tend to drive specific failure patterns. We see the same handful of issues every season.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
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 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.

One we ran last year
Got a call last month from a downtown Minneapolis home — 1980s 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 before lunch, billed flat-rate at $630.
