Our reputation is built on results. Here is what our customers have to say.
"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."
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
"We were having a lot of problems with our old plumbing in our house and these guys were able to fix it. Very professional, polite and fair prices. We were really fortunate to have found them. Extremely recommended!"
