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.
Homes in De Soto range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to slab leak detection. Our De Soto plumbers know the local housing stock, soil conditions and water quality, so you get a lasting fix instead of a temporary patch.
