Real feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"Installed a new garbage disposal and replaced the old P-trap. Cleaned up everything before leaving. Very professional."
"Main water line burst and we had a river in the front yard. They isolated the break, got the water back on within a few hours, and replaced the section cleanly the next day. Excellent emergency response."
"My hot water was not working so they replaced and adjusted the regulator valve, then repaired the shower diverter and replaced the hot and cold valves. Now I can easily have hot water and it feels like a new shower again. They even picked up the parts I had ordered in Hollywood at Ferguson Plumbing Supply."
