Get matched with top sewer main install, replace or repairers in Mayo, MD

"I had a plumbing issue that I thought would turn into a major headache, but Mahon Plumbing made the whole process smooth and stress-free. They arrived on time, quickly diagnosed the problem, and had it fixed before I could even make a second cup of coffee. They were professional, knowledgeable, and even gave me a few tips to avoid future issues. The pricing was fair, and there were no surprises on the bill—just great service from start to finish. If you need a plumber who knows what they’re doing and won’t leave you with a mess, I highly recommend Mahon Plumbing. I’ll definitely call them again for any future plumbing needs!"

"Owner came out promptly when we called for a sewer line backing up into our basement. His quote was better than another we received an hour before, and he had the equipment ready to go immediately. He cleared the blockage and advised us to pursue a video inspection because of a snag in the line (possible rupture in the pipe and/or tree root) that likely contributed to the backup."

"Our sewer line collapsed unexpectedly, and I was stressed about the cost and the mess. Dwayne Young made the process so much easier than I expected. They arrived on time, treated my property with care, and kept me updated every step of the way. The crew worked quickly, cleaned up after themselves, and the pricing was more than reasonable for the amount of work involved. It’s rare to find a company that’s this honest and reliable. Highly recommend their sewer line repair services!"

"He came out on Labor Day and worked harder than I could imagine and SOLVED a drain problem that I had been struggling with for years. My basement drain used to backup every few months and never drained fast no matter how many plumbers I hired (4!), but since he fixed it Labor Day 2025, the drain drains quickly with zero backups!"

"The plumbers were friendly, professional and on time. They performed the job in a timely fashion, cleaned up and were very thorough. I would highly recommend them to others."

"The job was done quickly and professionally. We received a realistic quote and the work was completed thoroughly without scope creep. They have become my first choice for plumbing."

"The work was excellent, they were professional and responsive. Jack Pumphrey is their regular plumber, and he was the one who came to install the pipe for me."

"The drain in our upstairs bathtub was clogged and it would not drain. I left a voice mail at about 8 AM, and Patrick phoned me back immediately. He arrived earlier than promised. After surveying the job, he told me it was a flat rate for the job and he went to work. He got the drain all cleared out and left the area cleaner than he found it. I know that the job was straightforward, but Patrick set himself apart from others we've hired with his courtesy and professionalism. We would definitely hire him again for plumbing work."

"John replaced our sewer line in the fall of 2013. What struck us about John when we first met him was his honesty. He treats his customers like he wants to be treated when someone works on his home. He doesn't overcharge or offer things that aren't needed. There are no hidden costs. He will go out of his way to make sure he helps people, agreeing to do our job in Virginia even though he usually only worked in Maryland at that time (he is licensed in both states). We felt his quote was fair and reasonable and he answered all of our questions in detail. Having a sewer line replaced can be a bit traumatic, just in terms of the destruction it causes in the yard. But John's work was excellent. He used up-to-code materials and when our water line broke in the process, he handled that emergency with grace and did not charge us extra. We thought the guy who did the back hoe work could have made our yard a bit more level when putting the dirt back, but we've had landscaping work done since then, and everything looks good now. That is something you'll want to plan for though in terms of cost. You'll definitely need to put in grass seed or sod, and maybe some creative bushes, flowers, etc. like we did. For our next plumbing job, we will definitely hire John again. He is an all-around great guy, very knowledgeable and we trust him with our home. We've also recommended him to a family member in Olney.
