"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"

"They replaced my leaking Poly water line from the street to the house with a new copper line. They tried to pull the new line through but were unsuccessful so they eventually had to trench through my yard to install the new copper line. In order to do this, they did have to cut through my concrete driveway which I had to get patched. After some adjustments were made with the new water pressure valve the system works great."

"This is a great company. Artie and Nick were right on time, provided high quality work. They were very professional and saved me thousands of dollars! My home warranty company in house plumbers had told me my main line sewer line had to be replaced (to deny a home repair a camera diagnostic). Replacing the main sewer line would have cost somewhere between $6,500 - $10,000. Artie and I met and reviewed my options. He recommended I go ahead and complete a camera diagnostic and simultaneously have anything in the line descaled. Their descaling machine has a camera attached to it. This process cost $750, but was far less expensive and time consuming than replacing a main sewer line. The end result, verified by camera, a clean sewer line! Thank you so very much BFMD for a job well done! Mary Ann"

"My guy at Abbott’s was very professional. He came to look at my pipes. First we had the sewer line camered to see if there were any issues. He gave me a good price. We didn’t even need to repair the sewer line so I was thankful. The guy was very helpful and talked with me through other possible issues I may have. He cleaned up and headed out after providing great service. I’ll go with Abbott if I have any other plumbing needs. Thank you"

"I had a sewer backup in my basement. Used Angi’s list and gave RTillery, Alex, a call. They were fantastic - great estimate, responsive, professional, courteous, quick in all their responses, the list goes on. I started with replacing the inside cast iron pipe. Alex even added a clean out. He and his crew were prompt, always polite and professional. They didn’t seem to mind my popping in to watch. The line was replaced in a day and a half w/ minimal water outage. After going back and forth I decided to replace the outside pipes. Alex provided several options. Other estimates would dig up the yard, sidewalk and driveway, replace the cast iron and terra cotta, but no cement work. RTillery slid the new PVC inside the terra cotta which was cheaper and less to dig up and they replaced the sidewalk! Only one other company offered to sleeve the PVC and it cost more! RTillery even came back to fix an issue they noticed doing their final checks. Wow! Can’t recommend these guys enough!"

"John is a good man, with experience to prove it. We have hired him twice now, to sort out a flooded basement (care of the City of Baltimore & their contractor, Spiniello), and then to retrofit all the horizontal pipes in our row home. Not only did he and his team solve our issues, but they made it look good. For a 120 year old row home, you can imagine the plumbing has been subject to a number of revisions, so it was a real pleasure to see them cut it all out (pipes corroded down to a pin hole), and replace every water bearing line with a singular, clear & straightforward system of logically placed cut-off valves, t-joints and what-have-you.
Because we had already had him out to solve a 1400 dollar flood problem the city blamed us for (and which later turned out to be their fault but they are not willing to pay for), he offered us this super low rate to get all the rest* upgraded (*all the main branches had been upgraded already, namely the verticals to the second floor). Johns original quote was for 1250 to do all the horizontals, so since i had him there i asked if he could run gas to our stove. Because of our recent purchases from him and since he was already there, he ran all the gas and got me two (all you need is one) gas cut off valves for an additional 150 bucks. 
Home Depot quoted me 500 for the same job.
John's number resides firmly in my phone.

"James did multiple jobs for me after diagnosing the actual problem. Correcting the issue required james to replace part of an old pipe which could only be accessed through a ceiling. James not only fixed the plumbing issue, he completed the carpentry work and repaired the ceiling. He also replaced my shower floor and the tiles surrounding it. James also replaced faucets on my utility sink. James is exceptionally knowledgeable, professional, and a master of his craft. I highly recommend hiring him for your plumbing needs and wants."

"As it turned out to be an A/C problem Rob didn't perform the service otherwise I'd have hired him for the repair on the spot.  He explained our issue and assured me that there wouldn't be any worse water in our basement while we were away which relieved my concern.  Rob also answered questions I had about our hot water heater.  He was nice and knowledgeable.  We'll definitely call him with our next plumbing project or problem.
