"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."

"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."
