"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."
"Had a new tankless water heater installed and could not be happier. The plumbers were punctual, clean, and walked me through the warranty and maintenance before leaving. Highly recommend for any water heater project."
"Once again Magnet Plumbing came to save the day. I manage a building of 49 units and we had a gas leak somewhere. The city shut the gas for the whole building. They showed up right away and got to work. They found the problem, fixed it, and were able to turn the gas back on so people could have dinner. Saul is amazing — right on time, very professional."
