"Clayton was understanding of the emergency of replacing the water service pipe since we were without water for several days. I was charged less than some of his competitors might have done. In this emergency situation he was very reasonable, he was reliable and on time and he completed the work in one day. Clayton brought a young man with him to repave the concrete sidewalk and his work was also blemish free. Clayton addressed my question and concerns in a professional manner!"

"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."

"Both Justin and Charlie came out and were very thorough in explaining the process. I was very pleased and well informed in what was happening when replacing my main water service line. The crew that came out were in time and did a great job in communicating and avoiding disruption to the property. I reached out to my community on recommending a good plumbing company; after a total of about 25 responses, 22 of them suggested Heil Plumbing! Thank you to the family and crew of this company and I will make sure the appreciation is communicated through our social networks."

"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.
