Our reputation is built on results. Here is what our customers have to say.
"We had a slab leak that nobody else could pinpoint. The Magnet team used proper leak detection equipment and found it under the kitchen in about thirty minutes. The repair was clean, no extra damage to the flooring, and the pricing was honest. Highly recommend."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
"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."
