Get matched with top sump pump installation pros in Baltimore, 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!"

"Extremely well! Very pleased. Honest guys!"

"This is a family company that does good work. I had used them two years ago for a backed up sewer line so I used them again this time. I am still pleased with their service."

"The service tech came to my home and did an assessment of the issue. Found the leak in the gas line, showed me where it was leaking. He told me what needed to be to fix the leak, gave me a quote, got his tools and started working. The whole process took about 30mins or less and he was done. I checked my burners to make sure the gas was flowing properly. Everything was put back in its original place and there was nothing to clean up afterwards. Great Job. I would recommend this company again."

"Our first encounter with Len the Plumber for gas boiler repairs went well and lead us to purchase a service contract with them for the 15% discount. However once we needed actual plumbing services and after they provided their "free" HVAC annual inspection it all went downhill rapidly. As others have noted the %15 discount is a concept they don't really honor. We were charged $1100 for less than 30 minutes of work for a repair that only required one cut and a simple joint (We had already removed the drywall and trim for access) and about $30 in parts (which by the way good luck getting an itemized bill from these people). On the HVAC side they broke what was a perfectly functioning 4 yr old AC HVAC and then wanted to charge $1200 to figure out how they broke it plus whatever parts they dreamed up needed replacing. They tried to claim the capacitor was bad. BTW - they brute force discharge the capacitors on units as part of their "maintenance check", something they should never do. We had BGE come out since their info was on the installation tag on the air handler and they diagnosed the issue in less than 30 minutes finding the thermostat had been burned up by mis-handling by the Len tech. They also said they never brutalize the capacitors the ways these guys do unless there is already a suspected issue with it. That's because the capacitor could be damaged by the way they handle it at Len the Plumber. So the "free" annual HVAC check cost me 3 days of discomfort and $250. Len refuses to admit wrong doing and will not reimburse us. They got $5000 in fees from us in less than a year so they don't care if we leave because they know another sucker is just around the corner waiting to be taken. These guys should lose their license given their business practices. Stay away from them at all costs."

"I accidentally broke the PVC pipe leading out of the condensation drain coming out of my air conditioning unit. (This may seem to be a minor problem, but that is only because you didn't have to haul the buckets of water produced during this heat spell to the sump pump drain.) I put in the request on Monday afternoon. They arrived first thing Tuesday morning -- early. It took them all of about 15 minutes. I could not ask for better service. They were prompt, professional, friendly, and courteous."

"I've actually hired Mr. Jones for 3 different plumbing jobs at my house. He fixed my leaking faucet, found and repaired a leak that I had in a bathroom pipe where he had to cut into the ceiling to identify the problem and fixed it - it was an after-hours call, and when I missed the county's original deadline for my backflow test, I called him and explained the urgency and he came the next day and took care of the test and submitted my results to the county. He's always been pleasant and punctual. I've referred family and friends to him and I'll continue using him for my plumbing needs. Thanks, Mr. Jones!"

"Great! I called after hours and Rick was pleasant. He asked to text a picture of the leaking. Brad was here in the morning. One hour later he was finished The price was reasonable. Would definitely hire again"

"Sam is very professional and friendly. Service was within my budget and he answered all my questions. I will hire him again."

"Vernon offered to check out our AC the same day. He called before arriving, and once he was here quickly went about his work, explaining to me what he was going to do and why. He quickly diagnosed the problem and solved it. We’ve found a new HVAC maintenance company we can count on. Great service, great responsiveness, good prices. Our AC is back up and running. Thank you, Vernon, and thank you Hamilton!"
