"Derrick was so helpful! He identified and repaired a leak for us, replacing our water filtration system under the kitchen sink. He was persistent and professional. I would absolutely hire him again."

"Our home is about 9 years old and we were quite shocked to have a leak in our main water supply line coming from the street to our home. We contacted several plumbers and listened to their approach as to how they were going to determine where the leak was coming from and whether they were going to repair a section or replace the entire water supply line. After meeting with the different plumbing contractors, we learned different methods of running a new water main line since it appeared that we would need it. We received new pieces of information from each proposal. We did not like living without water, however; since it was a big financial commitment, we did not want to be pressured or feel rushed into making a quick decision. On Saturday evening we sent an email requesting a quote from Mahon Plumbing and much to our surprise, we received a call just minutes after the email was sent. An appointment was made for the next day (Sunday). Immediately after meeting Greg, the owner of Mahon Plumbing, we knew his approach was the right course of action. With 100% confidence, he knew we just needed a repair, NOT a replacement of the entire main water line. He quickly identified where the leak was originating and guaranteed that ONLY a repair was necessary thus avoiding any sidewalk, walkway, underground sprinkler system or landscaping damage. We knew he was the right person for the job. Greg was well EXPERIENCED, HONEST, UPFRONT, had INCREDIBLE INTEGRITY, AND RESPECT for protecting our home by NOT automatically approaching our project by using heavy equipment, tearing up our sidewalk, walkway, underground sprinkler system, and landscaping to make it an easier job. We hired him on the spot. We had lower estimates for the repair. Most people would have used his confidence of a repair and gone with the cheaper proposal; however, we knew that we would incur additional expenses to repair/replace our landscaping, lawn, underground sprinkler system, and walkway. In the end, if we chose the cheaper proposal, it perhaps would have cost us the same, if not more. It may have felt better to spend less upfront, but, in the long run, it was far better to hire the RIGHT person would do the RIGHT job from start to finish. It was wonderful to see our property taken care of with such pride, as if it were theirs. Our grass was restored perfectly and they even did a repair on our sprinkler line. They left our walkway, landscaping, lawn, and underground sprinkler system intact. Not only did they do a perfect job for us, they had respect for the BAY and cleaning up the debris so it wouldn’t wash into the sewer system. Sometimes you pay a little more up front, but it saves aggravation and additional unexpected expenses in the end. Separately every plumber submitted a proposal for a continuous running sump pump. Every proposal recommended that we needed to replace the sump pump. However, Mahon Plumbing suggested that it might only need to be repaired. Only the backflow valve needed to be replaced. Again, Mahon Plumbing’s approach was correct! A special thanks to everyone at Mahon Plumbing for performing perfect workmanship. If you are looking for a true professional, then Mahon Plumbing should be your first and only call. T"

"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."
