Alfa Construction is a Bellingham, Massachusetts contractor that has narrowed its focus to one thing: full-home siding replacement, done in Hardie Plank fiber cement, vinyl, cedar shake, clapboard, board & batten, and engineered wood, for homes and multi-family buildings across MetroWest and central Massachusetts. Its site says Fabio founded the company in 2006, starting with general residential construction before settling on siding as the specialty, and its Massachusetts home improvement contractor registration is active.
The reviews back up the scope. A 2025 Google review described hiring Alfa after "a very disappointing experience with a previous contractor" and found the crew courteous and thorough, explaining each step along the way. Another, on Angi, described a full siding replacement where lots of questions were answered promptly and the work came out great. A different reviewer credited Fabio and his crew with handling several parts of a new-home build at once — Hardie siding, trim, Trex decking, painting — finished on time and within budget. Across eight reviews on Google and Angi, all five stars, the same themes repeat: responsive communication, a clean job site, and a crew — sometimes named as Fabio, sometimes Fabiano — that takes evident pride in the finish.
Two things are worth asking about directly. The registered license (192348) traces to the legal entity "Alfa Construction & Cleaning Services Inc" at the same Bellingham address, phone, and owner name as the siding business — almost certainly the same operation under its formal filing name, but worth a quick confirmation. There's also a mismatch in how long the company has been around: its own site says 2006 and 20 years, while its Angi profile lists 9 years of experience — the two don't line up.
The certifications on offer — James Hardie fiber-cement, Andersen's 400 Series windows, ENERGY STAR-rated installs, Tyvek weather barrier — are all self-described rather than independently verified here, so it's worth asking to see the manufacturer paperwork if that matters for a warranty. For a full siding tear-off and replacement, this is a contractor with a consistent, recent five-star record and an active license; just don't expect them to take on a small patch repair, since the company says it doesn't do that kind of work.
