The largest job under Da Silva Carpentry's name is not carpentry as most people picture it: a $220,000 detached garage with an attached home gym in Sharon, permitted in 2023. Isildo Da Silva runs the business from 2 Westboro Road in Upton. The rest of the permits come back to decks, porches and finishing work — a $55,000 deck rebuild in Upton in 2024, a $34,000 all-season porch and a $30,000 basement finish there in 2022, and a $17,000 siding replacement on Glen Avenue in Methuen in 2021. Foundation push piers in Springfield followed in 2024, and electrical and gas permits have been pulled under the name in Arlington, Merrimac and Malden, so the work travels well beyond one town. Fifty-five permitted projects sit on the BuildZoom page in all, five of them in the last three years. The offering listed there is cabinets, doors and windows, decks and porches, deck repair and finish carpentry. For a deck, a porch or a basement build-out with real money attached, that is a useful history to have behind a bid. BuildZoom shows several Massachusetts licence numbers under the name, among them a home improvement contractor registration, #210797, and a construction supervisor licence, CS-118989. Look those up on the state's register before you sign, and get the scope, the price and a current certificate of insurance in writing.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Da Silva Carpentry. Use it to sanity-check bids, then get the real number in writing.
A typical single-level deck is 12×16 — about 200 sq ft.
