Slab Leak Repair in Arlington, TX

Two things make slab leaks a defining plumbing problem in the DFW Metroplex. First, almost every home here is built on a concrete slab foundation rather than over a basement or crawl space — which means the water supply lines often run through or beneath the slab. Second, North Texas sits on expansive clay soil that swells when wet and shrinks when dry, putting the slab and everything embedded in it under constant seasonal stress. Add aging copper lines reacting with concrete and minerals, and pinhole leaks under the foundation become almost a rite of passage for older homes.

A slab leak is sneaky. The water has nowhere obvious to go, so it travels along the underside of the slab, soaks into the soil, and works its way up — showing as a warm spot on the floor, a doubled water bill, the sound of running water with everything off, or new cracks as the soil shifts beneath the foundation. By the time it's visible, it's often been leaking a while, which is why fast, accurate location matters so much.

Once we've pinpointed the leak, we walk you through your real options. Sometimes a single spot repair through a small access opening makes sense. More often — especially when the existing line is aging copper that's already failing in one place — rerouting the line overhead through the walls and attic is the smarter long-term fix, because it abandons the problem pipe entirely without breaking up more of your floor than necessary. We'll lay out the costs of each so you can decide.

Spot repair is the right call for a single, accessible leak in an otherwise healthy line. A reroute makes sense when the under-slab line is aging copper that's likely to leak again — we abandon that section and run new pipe overhead instead of cutting deeper into the slab. A full repipe is the best value when you've already had multiple slab leaks, because chasing them one at a time costs more than replacing the failing system once. We'll show you which path fits your situation and your budget honestly.
