V Castillo Construction

V Castillo Construction is a Waltham general-contracting outfit run by Mario Velasquez — Thumbtack's own profile describes an 11-year history as a deck and roofing contractor, and the company holds an active Massachusetts home improvement contractor license. The reviews on file line up around one thing: deck work done carefully and with attention to detail. In 2025, one customer had their deck rebuilt with new Trex decking and vinyl railings, and called the crew professional and punctual, cleaning up after themselves each day even after the team found unseen damage to the support structure underneath. Another 2025 review described a rougher patch — dissatisfaction with how some of the wood had been cut — that Mario fixed the very next morning after being told about it. A 2023 review covers a front porch rebuild with new shutters and a freshly painted door, again noting a hardworking crew that arrived early and cleaned up daily. Thumbtack also lists the company for roofing-adjacent work — gutter cleaning, shingle and tile repair, flashing, and soffit and fascia repair — though none of the reviews on file describe a completed roofing job specifically. There isn't much to flag: no negative reviews turned up, and the license is active and verified. The one thing worth knowing is that the written record is thin — 10 reviews across Google and Thumbtack, all five stars — so it's worth asking for a couple of recent references before a larger project. For deck rebuilds, refinishing, and general carpentry-adjacent home projects around Waltham, V Castillo Construction has a clean, consistent record so far, with a licensed, hands-on owner who has shown he'll return to fix a problem without being asked twice.
