Real feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."
"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."
