Justin Kelly Contracting

When people in a Cambridge subreddit trade names for general contracting, Justin Kelly's comes up. "For GC needs, Justin Kelly," one commenter wrote in May 2026, describing him as a good guy who's friends with just about everyone in town; a second thread that same month put him on a short list of local builders worth asking. The business describes itself as a general contractor doing full-service commercial and residential construction, remodeling and project management around Greater Boston. Its Massachusetts home improvement contractor registration, #181681, is active, and the Better Business Bureau grades it A+ and puts it at 24 years in business. Where to find them is worth pinning down first. The company's site says Everett; its BBB and Houzz profiles both list 476 Windsor Street in East Cambridge, and a 2023 Google reviewer left a single star saying that address wasn't the company's. For a Greater Boston remodel or build with an active state registration and local word of mouth behind it, this is a fair call — settle which office you're dealing with, ask who would run your job day to day, and get references from recent projects like yours.
