Connaughton Construction

Connaughton Construction has been building and renovating homes around Boston for more than four decades, according to the company — a run that traces back to founder John Connaughton, who started as a carpenter working on Back Bay and Beacon Hill townhouses before growing the firm into a Waltham-based custom-home and remodeling outfit. Several of its project managers, the company says, have stuck around 23 to 35 years, which tracks with a business built for long, complicated jobs rather than quick turnarounds. The clearest outside validation is a February 2026 Boston Magazine feature on a home renovation the firm carried out with architect Guy Grassi — knocking down the wall between a dining room and kitchen to open up the floor plan, a change the homeowner called "a game changer." Beyond that press mention, the paper trail is mostly directory numbers rather than customer stories: an A+ grade with the Better Business Bureau (it isn't BBB-accredited), a perfect 5.0 average across five Houzz ratings, and a Massachusetts home improvement contractor registration, HIC #137130, that's verified active. BuildZoom's permit records list 46 completed projects and Houzz shows 11 in its portfolio, but none of the three actually publish written reviews to read — so the ratings are real, but the customer's own words aren't there to check. The company says it works Boston, Brookline, Newton, Chestnut Hill, Weston, and Lincoln, and its BBB and Houzz listings both point to the same kind of work: new construction, additions, custom homes, and kitchen, bathroom, and historic (including Victorian) renovations. For a homeowner considering a custom build, an addition, or a full-scale renovation of an older home, this is a long-tenured, cleanly-licensed outfit with a real press credit behind it — worth asking for a few direct references, since the public record is heavier on badges than on customer accounts.
