"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."
"Bought a new house and had a pre-purchase sewer camera inspection done. The plumber walked me through the footage and pointed out one section that would need attention in a few years. Honest assessment, no upsell pressure."
"Called Magnet Plumbing when our old 40-gallon tank started leaking. They came out the same day, gave me a fair quote on a tankless replacement, and had it running by end of day. Could not be happier with the work or the price."
