A Harwich renovation had stalled — the original contractor declared bankruptcy after months of delays — when Estevam Castro took it over, pulled together the independent trades it still needed, and finished the house; the homeowner wrote that up in July 2025. Cape Cod calls Castro Finish Carpentry for jobs at about that scale: a whole exterior, a gutted interior, or both at once.
The company is based in Sandwich and describes itself as a finish carpentry contractor working across the Cape — trim, siding, decking, windows, doors, roof repairs and general home repairs — insured and licensed in Massachusetts. Customers write the owner's name three different ways, Estevam, Stevan, Steve; a June 2025 reviewer mentions his wife, Williana, on the customer-service side.
What people describe most is the outside of a house. Cedar shingles and Hardie siding, replacement windows, new trim and rakes, decks, a covered front porch, reroofs with skylights. On Google the company holds a 5.0 average across 47 ratings, with Angi at 5.0 from nine more, and customers keep mentioning the same practical things: the crew turns up every day, sweeps the site before it leaves, and hits the date it quoted. One out-of-state owner of a second home said in October 2025 that Steve kept them current with photos, texts and emails while the ocean-facing side of the house was rebuilt. Another, in June 2025, put the cedar-shingle estimate at 29% below the average bid received.
Work here has a way of growing. A May 2026 siding, window and porch job turned up water damage that had to be repaired once the wall was open; a January 2026 customer described a few hiccups on a full window-and-siding replacement, answered immediately. On the larger renovations Castro coordinates independent contractors rather than putting every trade in-house, so ask who is doing which piece before a whole-house project.
Its Massachusetts home improvement contractor registration is active, and the Better Business Bureau grades the company A+. For exterior envelope work on the Cape — siding, roof, windows, decks — or a renovation that needs one person steering several trades, this is a straightforward call; settle in the written quote how rot or water damage found behind the siding gets priced.
