John General Carpentry works out of Somerville, describing itself as a licensed and insured carpentry and general construction shop built on years of hands-on framing and finish-carpentry experience. The reviews people leave after hiring them keep repeating the same thing: speed and follow-through — a job finished in a day, cabinets assembled and a front door swapped in the same visit, a deck-and-bathroom job that came out exactly as planned. Across Thumbtack and Google, the six reviews on file — all from 2026 — run a perfect five stars, and they aren't the vague kind: one customer names the exact work (cabinets for a clothes closet, plus a new front door), another calls out reasonable pricing alongside the quick turnaround. Thumbtack lists 34 completed projects, and the company's Massachusetts home improvement contractor registration checks out as active in the state registry. There isn't much yet to raise as a concern — the written record is short, just a few months deep, and the business is brand-new to Angi, still waiting on its first review there. For a straightforward carpentry job — built-ins, a deck, a door or window swap — the early record here is clean and specific. Worth confirming scope and timeline in writing before the job starts, since most of what's documented so far is fast, single-visit work.
John was great! He was able to finish the job in one day and delivered exactly what I wanted.
Will hire again
John was extremely professional, courteous and knowledgable about the carpentry craft. Their prices were reasonable and they completed the job pretty quick while not compromising quality. I would recommend and intend on hiring them on future projects
It has been a pleasure to work with John. He is extremely knowledgeable and a great craftsman. I would highly recommend him for your next project
Our new deck and bathroom renovation both turned out fantastic.
