Justin H. Gamache Construction, LLC

Justin H. Gamache Construction, LLC is a Middleborough, Massachusetts carpentry and construction company run by Al and Justin Gamache, a father and son who describe themselves as the third and fourth generations of Gamache builders. The company works on interior remodels, exterior work including siding and doors, additions and ground-up builds, and reports 30 years in business. Its Massachusetts Home Improvement Contractor registration, 217847, is verified active in the state registry under the company's own name. The reviews here are unusually detailed for a company this size, and they cluster around new construction and custom carpentry. A 2022 reviewer waited a full year after her new-construction home build before writing, to cover every phase, and described Al helping her find a designer for plans and pull demolition permits, and staying with her through Conservation Commission issues before a contract was even signed. A 2025 reviewer said Al stuck with them through town meetings, and was the only carpenter who gave them the hard truth that they should rebuild, when others stopped answering once they saw the nearly 200-year-old house. A 2023 reviewer praised the crew for showing up on time each day and singled out Justin as attentive and detail-oriented. Speed and scheduling come up too: a 2024 reviewer described two jobs, the first a rush finished before an insurance deadline and the second a slider and back door installed well before the holidays, calling the crew professional, clean and fast. A 2025 reviewer said problems that came up during the work were handled properly and visitors noticed the quality of the workmanship. Siding work is mentioned in a 2022 review. Across Google the company holds a 5.0 average from 22 ratings. Nothing negative is on file, but the written record is nine reviews on one platform over four years, so the picture is consistent rather than heavily tested, and several of the accounts describe large custom projects rather than small repairs. For a new build, an addition or custom carpentry in the Middleborough area the evidence is strong; confirm the registration number and get the scope and schedule in writing.
