Signs of a Slab (Under-Slab) Leak

A slab leak is a leak in the water lines that run under your home's concrete foundation. Because the water is hidden, the early signs are indirect: a warm or damp spot on the floor (often from a hot-water line), the sound of running water with everything off, an unexplained jump in the water bill, low pressure, or new cracks in flooring. Pinpoint electronic leak detection finds the exact spot so the repair is targeted instead of guesswork.

• Warm or damp patches on the floor often signal a hot-water slab leak.
• Running-water sounds with all fixtures off, plus a rising water bill, are classic clues.
• Left alone, slab leaks undermine the foundation and ruin flooring.
• Electronic leak detection locates the spot so repairs stay targeted.
