Middlesex Custom Builders LLC

Additions are what this firm mostly builds — decks, porches, a mudroom, a finished basement — and in four years exactly one customer has written anything about it. Middlesex Custom Builders runs out of 7 Sherman St in Maynard under Eric Sosa. Nineteen permits are on file, twelve of them in the last three years, at a typical value around $46,000. Most sit in Maynard itself: a $130,018 mudroom addition with a front porch and kitchen remodel in 2022, a $50,890 basement finished into a playroom in 2025, deck rebuilds and new egress doors. A few land further out — a 2023 remodel of a kitchen and two bathrooms on Beverly Ave in Marblehead, a $90,411 above-garage addition in Newbury the same year, a Belmont bathroom in 2022 and a Rowley deck. The single written account is worth reading closely, because it is all there is. In January 2022 a homeowner named Alexandra described her kitchen renovation and called the owner, Eric, a master carpenter — praising the creative solutions, the craftsmanship, and an estimate that was detailed and easy to understand. Specific, first-hand, and now four years old. The paperwork raises one question worth asking outright. BuildZoom lists a Massachusetts home improvement contractor registration, 203953, as active, but with a date issued of 2 February 2026 — while permits under this company go back to early 2022 and the same page's own blurb credits four years of activity. That may be a renewal rather than a first registration, but this is a directory listing, not a state confirmation, so put the question to them and check the number with Consumer Affairs and Business Regulation. Who it suits: someone around Maynard planning an addition, a porch or a basement finish, and comfortable judging a builder largely on permitted work rather than on written accounts. Ask for two or three addresses from the last year, the registration number in writing, and current insurance certificates.
