From downtown Potosi to every corner of Potosi, MGA Plumbing provides expert slab leak detection with upfront quotes and a satisfaction guarantee. Book online or call (888) 480-9811.
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.
Watch for warm floor spots, a running water sound, cracked tile and a water heater that never shuts off.
Because we dispatch from the St. Louis Metro area, a MGA Plumbing plumber can usually reach any address in Potosi 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.
