A slab leak is a leak in a water pipe running beneath your home's concrete foundation. Because it is out of sight, it can go unnoticed while it quietly drives up your water bill and damages the structure above.
Common signs of a slab leak
- Unexplained increases in your water bill
- Warm spots on the floor, especially over a hot-water line
- Sound of running water when nothing is on
- Damp carpet, buckled flooring, or cracks in hard flooring
- Musty odors or signs of mold near the baseboards
Why it matters
Water under a slab can undermine flooring, promote mold, and waste a significant amount of water. Left alone, a small leak can become a larger and more expensive repair.
How it is found
Professional leak detection uses acoustic, thermal, and pressure testing to locate the source with minimal disruption, confirming the exact spot before repair.
Repair options
Depending on the location and condition of the pipe, options range from a targeted slab leak repair to rerouting the line. Call (800) 390-6351 to talk through the best approach for your home.
