"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."
