BD Construction and Design

BD Construction and Design works out of 63 Brewster Ave in Winthrop, and the firmest thing known about it is the paperwork. Its Massachusetts home improvement contractor registration, number 216302, is active in the state registry under the company's own name, and Brian Derosier holds an active Massachusetts construction supervisor licence, CS-121767. That second one is the credential that matters when a remodel touches structure — and the number the company self-reports on Angi is the same one the registry shows, expiring in June 2029. On Angi it presents as a general repair and remodeling outfit rather than a single-trade shop: handyman work and major home repair at one end, basement, kitchen and bathroom remodels at the other, with decks, doors and windows alongside. Seven project galleries are posted and estimates are free. What is not there yet is anyone's account of the work. Neither Angi nor HomeAdvisor carries a review, so nothing here speaks to how this crew finishes a job, holds a schedule or handles a problem — in either direction. That makes the decision a simple one to frame. The credentials are current and verified against the state, and the trade mix covers most Winthrop punch lists and mid-size remodels. Since there is no customer history to lean on, do the legwork yourself: ask for addresses of the jobs in those seven galleries, ask for two references you can call, and get a certificate of insurance in hand before anyone starts.
