O'Connell Carpentry is a one-man-plus-crew operation run by Pat O'Connell out of Watertown and Belmont, Massachusetts, doing carpentry and remodeling work — kitchens, bathrooms, additions, decks, porches, and finished basements — for homeowners across the western Boston suburbs. The company says it's been at it more than two decades, and Better Business Bureau records list it as a sole proprietorship operating since 2003 with two employees. The paper trail here is thin. BBB and Houzz both report no published customer reviews, and the only outside account on file is a Reddit post from February 2026, where a homeowner who says they've hired O'Connell Carpentry for a couple of projects calls the work good enough to use again and specifically vouches for Pat and his team. Houzz's profile does show five finished project galleries — kitchens in Weston, bathrooms in Cambridge, decks in Waltham — and a separate BuildZoom profile for Patrick O'Connell in Belmont lists 37 projects and a perfect business score, describing 24 years in residential construction and remodeling. Worth clarifying before hiring: BuildZoom lists a carpenter license and a home improvement contractor license number for the business, but neither has been checked against the state registry, and a separate BuildZoom page for a similarly named "O'Connell Carpentry & Construction, Inc." in Quincy shows those same two numbers as inactive — make sure you're looking at the right company's current license before signing anything. This is a small, established local carpentry and remodeling shop with an A+ BBB standing but almost no public track record to check against — worth a call to see recent local project photos and current references directly, especially if the job is a full kitchen or bathroom remodel.
“We've used O'Connell Carpentry out of Belmont for a couple of projects and will continue to use them for our projects moving forward. I can't recommend Pat and his team enough.”
