Quick answer
A slab leak is a break in a water line running beneath a concrete foundation. Common signs are warm spots on the floor, the sound of running water, cracks in flooring and a sudden jump in your water bill. The three repair options are a spot repair through the slab, rerouting the line through walls or the attic, or repiping the home.
Slab Leak Repair you can count on
Slab leaks are one of the most common plumbing problems in North Texas. Most homes here are built on concrete slab foundations, and the water lines run underneath. When the clay soil swells and shrinks, or when pipes wear thin from age and water chemistry, those lines can crack.
We locate the leak electronically, then explain each repair option with its pros and cons. Often the best long-term fix is to reroute the affected line overhead so you never have to break the slab again for that pipe. Whatever you choose, we coordinate the work to minimize disruption to your home.

What affects the cost of slab leak repair?
Slab leak repair costs depend on how deep and where the leak is, the type of flooring above it and which repair method you choose. Rerouting often costs about the same as breaking through the slab but avoids damage to flooring. We provide a written comparison of each option before any work begins.
