John Lynch Builder, LLC

John Lynch Builder is a Cambridge, Massachusetts general contractor built around whole-house work — full gut renovations, historic-home projects, and additions rather than single-room jobs. The company's own site says it has been operating more than 40 years out of Cambridge, doing general contracting, historic home renovations, and remodeling. The written record behind that is small but consistently strong: Google currently shows a 5-star average across 4 ratings and BuildZoom a 5.0 average from one review, and the accounts behind those numbers describe real projects. In a pair of 2020 reviews, homeowners described a full gut renovation "done on schedule, on budget, and according to our wishes," and a separate whole-house remodel where "John and his team took time to understand our vision." Another 2020 review described a bathroom remodel that extended into the surrounding rooms, praised for staying clean start to finish. One reviewer noted having used them for several projects, including a complete gut renovation. A 2016 BuildZoom review is shorter but points the same direction — good price, job finished on time. All five reviews on file date to 2016–2020, with nothing more recent showing up since. BuildZoom's directory listing shows an active Massachusetts electrician registration (#10449) and an active home improvement contractor registration (#172225) for the company, alongside two other numbers — a home improvement contractor license and a construction supervisor license — now listed inactive. These are BuildZoom's own claims rather than a state-registry verification, so it's worth confirming current status directly before signing anything. BuildZoom's permit data also credits the company with 49 recorded projects. For someone weighing a full renovation or a historic-home project in Cambridge, the track record on file is positive across the board, but it's also older and thin enough that a current reference and a fresh look at licensing are worth asking for before booking.
