From downtown St. James to every corner of St. James, MGA Plumbing provides expert slab leak detection with upfront quotes and a satisfaction guarantee. Call (888) 480-9811 24/7 for emergency help.
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.
