Commonwealth Building Inc

Commonwealth Building has been putting up retail stores, restaurants, and corporate spaces across New England and into upstate New York since 1979, when founder Frank Trainor, a carpenter by trade, started the company as Commonwealth Building & Remodeling. It became Commonwealth Building Inc. after a 1998 rebrand, and leadership has stayed close to home: Chris Fontaine took over as President & CEO in 2019 under a succession plan, with Trainor staying on as Chairman. By its own description this is a commercial shop through and through, retail chains, restaurants, corporate and commercial buildouts, and not a residential remodeler. Its Google page carries a perfect 5.0 average across five ratings, but the written record behind that number is thin: a single review on file, dating back to 2022, calling the crew good to work with, which isn't enough history to lean on heavily. The company points to nearly 50 years in business, membership in the Retail Contractors Association, and bonding for projects up to $5-10 million, credentials aimed at developers and property owners sizing up a commercial build rather than a homeowner comparing quotes for a kitchen or bath job. If you're a retailer, restaurant group, or commercial developer in New England, Commonwealth Building's decades of work with national chains are worth a call. Homeowners looking for a residential remodel should ask directly whether they take on projects of that size at all before going further.
