Watch for warm floor spots, a running water sound, cracked tile and a water heater that never shuts off.
Slab leaks occur when water lines under a concrete foundation corrode or shift. Left alone they can undermine the slab itself. We locate the leak electronically, then repair by spot access, rerouting the line overhead or — when warranted — repiping.
