Its MA plumber license 16532-PL-M, held by Kevin Decoteau, is active on the state registry. A 2023 lovelivelocal.com article said Kevin participates in Upper Cape Cod Regional Technical School's "Cooperative Work Experience," providing on-the-job training and mentoring for students in the plumbing field. In a 2020 review, KMD replaced a 50-year gas boiler and added an additional zone. In another 2020 review, KMD replaced a failed hot-water heater at a rental property: after a 10 AM call, they came at 1 PM to assess the situation and estimate, and completed the job by 10 AM the next morning. In a 2021 review, Kevin repaired a leak in a tough spot and advised about another potential leak in the other bathroom. In another 2021 review, Collin the plumber identified the problem and resolved it quickly. In a 2022 review, the plumber reconnected a gas stove, and the price was right within the estimated quote. In a 2023 review, KMD installed a heating system. In a 2024 review, KMD was the first company to provide an assessment of existing conditions, with timely follow-through on quoting and scheduling. In a 2023 review, the reviewer wrote that while unwinterizing the house, the company blew out all the antifreeze in the system without approval, which cost over $1,200 to replace. KMD replied that the reviewer had the wrong plumbing and heating company and that it had not done any work for them.

Highly recommend KMD team. Start to finish - expertise, professionalism, and thorough communication. Have great confidence in the work performed and the process was seamless. Educated and experienced staff- Will use again!
Impressive experience from start to finish. Communication through execution was professional and quality. First company to provide educated assessment of existing conditions and timely follow through with quoting and scheduling. The technical skill and professionalism met and exceeded my expectations. Will recommend and use again.
They unwinterize my house and without my approval they blew out all my antifreeze in the system which cost me over $1,200 to replace . They claim there was air in the lines which doesnâ t require blowing out my antifreeze. I would stay away from this company .
Awesome customer service and quality job! They communicated and performed the work as expected with no delays or issues. Would hire again in a heart beat.
