McGrath Construction Co

McGrath Construction has been building and remodeling around New Salem for 37 years, run by owner Justin McGrath since 1989 according to the Better Business Bureau, which gives the company an A+ rating (though it's not BBB-accredited). The written history here is recent and consistently strong: nine of ten reviews on file were posted in the last six months, and every one is five stars. Roofing shows up more than any other single job. A June 2026 review describes several different roof projects over the years — metal roofing on a porch addition, a metal replacement roof on a bedroom wing, and a roof reconfiguration over a mud room, most recently a roof over a closet addition. Another June 2026 review describes a roof replaced in a single day, followed immediately by hiring the same crew for new vinyl siding. A third describes a metal roof the homeowner thought was out of budget until McGrath made it work. Reviewers also describe bigger, multi-trade projects: a solarium and small deck added alongside a new roof despite freezing weather; a sun room and barn office built with new windows and doors; and, in a November 2025 review, a third project for the same repeat customer — after finishing their basement and then a kitchen with granite countertops and new hardwood flooring, McGrath's most recent job for them was a master bathroom remodel. The company's own site lists a Massachusetts unrestricted construction supervisor license (CSL 102057) and a home improvement contractor registration (HIC 163443); HomeAdvisor and Angi separately show the same license number, unexpired until February 2027, and both list the business as veteran-owned — none of this is an independent registry check, so it's worth confirming directly. The company also operates a second roofing-focused profile, McGrath Roofing & Exteriors, at the same address with the same license number, and its own domain. There's no negative account on file to weigh against the positive ones, and several reviewers describe using the company repeatedly across years and multiple projects — a strong sign of a working relationship rather than a one-off job that went well. For roofing or broader home renovation in central Massachusetts, this is a long-running, multi-trade contractor with a recent run of five-star, detailed accounts behind it.
