"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"

"Not sure if these guys are plummers or surgeons. Team repaired a broken water service line into the house within 24 hrs. Managed to spare landscaping and dig minimally - only at the curb to make the connection. Very professional and skilled team. Best plummers we've worked with in >20 years of home ownership."

"Fine. I was very pleased from start to finish at its different stages: clarified probable problem; inquiry about vaccination status; alert to me that the HVAC professional was on his way; greeting/introduction at the door; person was masked up & then put on booties over his shoes upon entering my residence; confirmed problem and solution; explained it to me in great detail (since I always have a LOT of questions); secured my additional fees (on-line w/receipt); ordered parts, which arrived QUICKLY; rescheduled a return-repair; fixed my water heater. ALA...I have hot water again. Easy-peezy. So grateful. In the end, we always pay for a trusted service provider. Dispatch person (one of the co-owners, Lori, was particularly empathetic to my situation as a person on a fixed income. Defininitely recommend to others."

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"My water heater started leaking on a Sunday. I reached out to Family Fire Service and they responded immediately. They had a new water heater out to my house the next day and installed in a few hours. The supervisor and the tech worked seamlessly to have us up and running. They provided quality service and at a very competitive price. I highly recommend Family Fire Service and Plumbing. KC"

"Outstandingly! The installer from Orbit, a young man name JOHN did an outstanding job of installing, providing helpful information, and providing and extra service which required repair of a leak in the main water line coming into the house. Great job of coordinating with the American Water Company worker to manage water shut-off and turn-on. I can't thank Orbit enough for sending JOHN to install my system. Anyone receiving his services in the future is in for a treat. John deserves a "Beyond the Zone" (Military personnel will understand that terminology) pay raise he is well worth retaining as a skilled technician and one H***-of-a-nice person, a great public relations entity for ORBIT!"

"Miracle Method did a great job resurfacing the floor, the bathtub and surround, and the shower and surround. Everything looks new. They even cleaned our existing shower doors to look new. They removed the toilets to resurface the floor and placed new wax rings when they replaced the toilets. The only negative part of the resurfacing process was the smell of the chemicals they use. We had to open a lot of windows to vent the odor."
