"I called at 8:00pm on a Tuesday night. The plumber came before 10:00pm as promised. He replaced a leaking shut-off valve and associated pipe within an hour. Cost was as quoted for one hour labor plus parts which were less expensive than expected. No extra costs for travel time or anything else. We will definitely use again."

"From start to finish a very positive experience! The work crew were very attentive to making sure my wife's native garden plants survived the onslaught of digging necessary to replace our home's water main. We are very satisfied customers and highly recommend BFMD if you need your water main repaired or replaced."

"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"

"Excellent communication from first contact, which is rare. RTillery was the obvious choice when I discovered the ditching drill they deploy is expected to take hours, not days, and they are the only ones doing it. Alex was great at explaining the process and the price was much lower than 3 other companies offering to replace the same pipe. I signed the contract and work started next morning. The job was completed quickly with no disruption"

"Several years back, I called for help and we talked through my problem. We concluded that no water was leaving my house and it was backing up out of a pipe in the basement. In talking through our architecture and location, he determined this was most likely something that could be solved by Baltimore City services (for free). That turned out to be the case. The City workers came out fairly quickly, identified and cleared the clog outside my home, and I paid nothing (outside of my tax returns, of course ... "my tax dollars at work"). Knock You Out could have tried to make some money off of me by saying they needed to come out and look at it, then referring me to the City, and then charging me for their time/truck-roll (while prolonging the entire thing for me). Knock You Out is not cold and unscrupulous. By spending time with me on the phone, but doing no work here and making nothing from it, they proved themselves to be honest and decent people. And that may be the main thing we shop for in home services."

"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.
