"Rob and his helper did an outstanding job."

"Created a toxic mess on the floor that took several hours to clean up. I requested a more detailed explanation of the problems he mentioned but no one did what I asked, even after several attempts on my part. Will not use again."

"Within 24 hours of my posting the need to replace my water heater the work was done - very efficient and easy!"

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"They were very professional. They showed up on time and did a great job. I was working from home and they caused minimal noise and disruption."

"Dereck was excellent. Did the job quick and was very professional "

"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!"

"Great service very prompt and easy to work with."

"I had a clogged toilet. I tried to resolve the issue using a plunger, then a snake, and finally pouring buckets of water from high up. Nothing worked. I called Len for the service. They left me waiting all day of my original appointment then texted me to reschedule and offered me a $50 discount. The next day their tech showed up. Nice guy, but he basically tried exactly what I had done e myself and I kept telling him that the toilet needed to be removed and try using the snake after that from both sides of the toilet drain.He had me sign for the charge in advance at $285 which I did. But when it came to removing the toilet he said it will be extra. I had to talk to the manager on the phone to explain that charging me extra was not fair. After arguing 5 minutes he finally kept the charge to the original amount he had quoted me. In the end nothing was fixed at the cost of $285. I plan to not only dispute the charge but also cancel my maintenance contract for my boiler. Never use them."
