Get matched with top storm drain installation pros in Frederick, MD

"It was a fairly nice experience talking with them - making a free inspection appointment and having the basement inspected. The inspector (Robert) seemed professional and the result and recommendation from the inspection sounded reasonable including the price. We would love to hire them, but there is another issue in the basement that needs to be done before their waterproofing service, and their service would not take care of it. We would recommend them to our friends if it is not like our case."

"Mahon Plumbing was not only professional, fair, and timely. Their professional courtesy and customer service was amazing. Couldn’t have made the process of installation any easier! Use Mahon Plumbing…no questions asked!"

"Professional, informative and personable staff. Cleaned up at the end of the day. Most importantly, there was no leaking during a recent storm."

"Once in a blue moon a person may find a contractor with whom they truly want to work--a person who values honesty, has expert knowledge, takes pride in his work, is conscientious, fair and punctual. In addition to these fine qualities, John was gracious, considerate and willing to go the extra mile. He installed a top-of-the-line French drain in my basement, which included features not offered by many of his competitors. It was done in 3 days, to the exact specs he kindly sketched out in response to my questions. When a glitch arose with the backup pump, his employee returned to do a quick fix the same day. After many years and much higher estimates, I finally have a basement that I feel will stay dry even in the worst of weather. I am very grateful."

"Excellent job all around. The work was done in late March, 2019, but I waited to post this review until after a heavy rainstorm. The storm of July 8, 2019 (>4"/hr) would normally have caused water to seep up through the concrete floor. After the storm, there was not even a drop. The sump was dry. The job was messy: jackhammers and lots of dust. They left it clean. One cannot even see where they cut the lawn to get the pipe to the curb. My only critique is that the new concrete poured to replace the broken floor should have been completely leveled. From initial estimate to installation, excellent work."

"Shawn and his entire team were friendly, polite and took great care to keep our home clean and with little inconvenience during the project of drain tiling and installing a sump pump in our basement. They also fixed a crack in the wall that was discovered after the estimate was created."

"I'm not fully moved into the home yet, but I will update when I am there permanently. The crew was very professional, worked diligently, cleaned up after every day of work (three day job--french drain expansion, two additional sump pumps installed, window drains into the sump pumps, pretty extensive job)."

"Bruce from GAC did both the estimate and the work on my home. We had three ceiling light fixtures installed, a fan rewired, an outlet installed and ethernet run. They were extremely professional from start to finish and made the entire process smooth as can be. Would absolutely recommend GAC for electrical service."

"Because of the great service from Best Buy I feel compelled to update my review below. My situation was complicated. A spring runs continuously under our slab, there was water in several places within our finished basement, and there was a leak under a supporting I beam. Best Buy, unlike other companies, warrants the entire floor, not merely the area around their work. This warranty is invaluable as my experience demonstrated. Andrew, the owner, and his crew came out at least 5 times, sometimes on short notice, once on Sunday, to figure out how to solve all of the complicated issues. They had to build a perimeter drain, a lateral drain, and a speed drain and they had to epoxy around the supporting beam. On one occasion I called because there was a damp spot in one place, but Andrew pointed out several others that I'd missed. Of course, it wasn't in his interest to do so as it required more work. I highly recommend Best Buy!"
