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.
Because we dispatch from the St. Louis Metro area, a MGA Plumbing plumber can usually reach any address in Cobalt fast — including St. Louis and O'Fallon. For slab leak detection emergencies, that speed is the difference between a simple repair and major water damage.
