Verified record
Commonwealth Building is a large, established general contractor based in Rockland — the company's own history traces back to 1979, when founder Frank Trainor, a former union carpenter, started it as Commonwealth Building & Remodeling; it incorporated in 1980 and took its current name in 1998. Leadership passed to Chris Fontaine as President & CEO in 2019 under a succession plan, with Trainor staying on as Chairman. By its own description, this isn't primarily a residential outfit: the company specializes in retail, restaurant, corporate, and commercial construction across New England and Upstate New York. It says it's a member of the Retail Contractors Association and carries surety bonding for projects up to $5-10 million — figures that point toward large commercial work rather than home remodeling jobs. The one review on file, from 2022, is a two-word "Excellent team!" with nothing to say about a specific project. Its Massachusetts home improvement contractor registration shows as expired in the state registry, though given the company's own description of its work as primarily commercial rather than residential, that registration may not reflect what it's actually being hired to do. Anyone considering them for a home project should confirm directly whether residential work is something they still take on.
