Real feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"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."
"Our main line backed up on a Saturday night and the Magnet Plumbing crew showed up within the hour. They cleared it, camera inspected it, and gave us a quote to fix the damaged section. Professional from start to finish."
"Replaced two old toilets with new comfort-height models. The installer was respectful, took his shoes off at the door, and hauled away the old toilets. Small things that make a big difference."
