"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"

"Review for 10-19-20 Silver Spring, Md. home I called Douglas & Son Plumbing to replace an old frost free outdoor faucet. Shawn Douglas plumber installed the new frost free exterior faucet that was twelve inches long and inside my house installed a shut off valve; furthermore, the plumbing code recommended. He neatly cut a small square box in the panel in the Den to find the pipe. After he found the pipe he installed a shut off valve for the frost free exterior faucet. His measurement was exactly correct to find the hidden pipe behind the outdoor wall. He explained that the exterior faucet should have a separate shut off valve. He had great rapport with the customer that is me and I was impressed that he used a lever to balance the frost free exterior faucet. I do not about any customer that was not satisfied with his work but he receive a five star rating for this job."

"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.

"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"

"Installation of our system was top notch and professional. 6 months after installation of my system, the salesman, Scott, immediately responds to any questions or issues that I have. Their service is great and the quality of our water is remarkable. We are very pleased and can't recommend Orbit Water / Puronics highly enough!"

"First I would like to say I would NOT HESITATE to hire Miracle Method Surface Restoration from Kensington, MD again. The office receptionist (Margaret) and the two gentlemen that did the cut out and install (Carlos and Luis) were EXCELLENT and I would rate them an "A" in all aspects of their roles in the company. The C responsiveness and C Punctuality related to the following: (1) a prearranged appointment resulted in a no show by the company head (this is not our residence); and (2) the representative that did come the next day did not have any photos of previous work or paperwork to move the project ahead. If it wasn't for Margret in the front office we would not have used this company; however, she went out of her way to get a photo of a cut out, ensured that the proposal was revised for details, and scheduled the work. Like I said in the beginning, I would gladly hire and recommend this company. Just be sure to confirm appointments."
