A Green Valley Construction, LLC

A Green Valley Construction works out of Westborough and takes the jobs homeowners describe by room rather than by trade — a bathroom down to the studs, a deck rebuilt from the footings up, floors refinished in a house that has been lived in for twenty years. Matheus, who most reviewers call Matt, runs the crew and turns up for the estimates himself. The Better Business Bureau lists the company as immigrant-owned on the business's own account, and grades it A+ as an accredited member. Its Massachusetts home improvement contractor registration, 208900, is verified active in the state registry under the company's own name — the check worth making before anyone opens a wall. Sixty-two Google ratings average a flat 5 stars, and the reasons repeat often enough to mean something. Bathrooms come up most. One homeowner brought Matt in after a previous contractor's tile job leaked through into the ceiling below; the whole space plus that ceiling were gutted and rebuilt in a little over two weeks. Another had three bathrooms done at once, with smart toilets, recessed lighting and interior glass doors. Decks and porches are the second thread — a two-story round Victorian porch restructured on budget, a deck and pool deck replaced, a porch support rebuilt on the downhill slope of a hill. The habits customers name are unglamorous and consistent: someone on site every day, dust contained, the work area swept at the end of each shift, and scope reshaped to fit a stated budget. Several describe hiring the crew again across multiple projects. One recounts Matt spotting a damaged cabinet the homeowner had bought, arranging the swap at the store, and coming back the next day to install the replacement without charging for the trip. The history runs 2023 to 2026 across 54 reviews and four sources, ten of them in the last six months. This is a dense and recent track record rather than a long one, which is worth weighing if your project is unusually large or tied to a hard deadline. Reviewers credit Matt personally for the suggestions, reminders and explanations at each decision point, and one describes the contract being adjusted with him before work started. So pin down in writing who is running your job day to day and how mid-project changes get priced.
