Get matched with top tankless water heater repair pros in Holbrook, MA

"He called us early morning and by early afternoon we had a new hot water heater. Very professional. I would recommend to all."

"This was a relatively small water heater repair, and Ryan did an outstanding job. He responded immediately to my request, provided a reasonable quote, was polite, professional, knowledgable, and friendly to deal with. Will definitely hire again if needed."

"Guy did a great job of diagnosing and repairing our State Hybrid Electric water heater. I would definitely recommend his work."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"Within hours of my inquiry on a Saturday, Bill was out to my house to assess my needs. I needed a new water heater and my AC repaired. I knew I would be looking at a lot of money, because I had other quotes. His price was amazing and the job was completed in less than a week! I would highly recommend this company."
