"Rob had recently replaced my kitchen and bathroom faucets and I called him to see if he could now replace my gas water heater. I was happily surprised when he said he’d be out within a couple of days and I was REALLY pleased with his estimate. For both jobs, Rob showed up when he said would and was both fast and efficient. He’s a great guy - dependable, reasonable, professional and focused on providing good service to his customers. Rob is my “go to” plumber from now on!"

"I initially hired them to fix frozen pipes and a broken water meter. They responded quickly to my call even though it was right after a blizzard. They also diagnosed that I had considerably high pressure, 110 in the house and adjusted that accordingly. I also chose to have them install a small heating system in the space under my house to help reduce problems with future pipe freezes. I have an unusual situation where my house is elevated because I am in a flood zone which makes the lower pipes more prone to freezing. They got the entire system and plumbing work done in a single day and now the underside of my house is much warmer and hopefully this will prevent future pipe freezes and bursts."

"Brian and his crew were great. Brian came out and gave a great estimate for everything I needed. He was very responsive via email as we worked to schedule a time for his crew to come do the work, which was mainly water tank and heating system maintenance. Brian brought Jim promptly and explained the work. They then pointed out a couple of things that they recommended replacing, one they just included in the original cost estimate and another they added on due to additional parts being purchased. Jim was very thorough and professional and, by all accounts, did great work. I’ll be using Heavy Doody for all of my future plumbing and heating needs!"

"John is hands down the best plumber I?ve dealt with. I had a frozen pipe and after calling multiple plumbers who couldn?t identify the issue or offered zero real help, John came through immediately. He showed up the same day I called, quickly found the problem, and had everything fixed within 30 minutes. He was knowledgeable, efficient, and clearly knew exactly what he was doing. After a stressful situation and a lot of wasted time with other companies, John made the whole process easy and painless. I wouldn?t hesitate to call him again and will be recommending him to everyone I know."

"Milltown was exceptionally responsive (before, during and after) the work was performed. Across the Milltown organization, they were responsive to my questions about water heater selection; Mike was responsive and a partner in selecting the best location for the new unit and after, Milltown and Mike were immediately responsive when part of the unit was not operating as expected. Milltown is a solid organization that takes pride in their work."
