Groton Mechanical, Inc. describes itself on Angi as a heating company that has been "taking care of all of your heating needs" since 1994. In a 2018 review, a customer said the company converted an old oil furnace to a new propane system, on time and on budget. A 2010 customer wrote that the company gave a quick estimate for a furnace/boiler replacement and did the job as estimated. In a 2013 review, a customer whose main sewer system turned out to be deteriorated during a french drain job said Dave came to Winthrop within the hour, when local plumbers could not come until later that afternoon. That 2013 customer said Dave also pointed out other plumbing issues and was being contracted to complete a bathroom that had to be demolished. A 2015 customer said the company handled several small plumbing projects and repairs and planned to hire them again. A 2021 customer described them as neat and timely and said the work was done for the price quoted.
They were very professional, neat, timely, and did the work for the price quoted. I would highly recommend them!
Quick, professional and very affordable. I would highly recommend!!!!
Converted an old oil furnace to a new propane system. On time On budget Couldn't be happier.
I have used Groton Mechanical for several small plumbing projects and repair and have been more than pleased with their response, promptness and work ethic. I will definitely hire them again.
Dave was called in an emergency situation. While having a french drain put in my basement it was discovered that my complete main sewer system was completely deteriorated. I had called local plumbers to see if they could come out immediately and no one could come until later that afternoon. Jason the contractor putting in the french drain called Dave and he came to Winthrop within the hour. He and his father were very professional and knowledgeable. Dave also pointed out some other issues dealing with our plumbing and we are contracting him to complete the bathroom that had to be demolished.
