McCarthy Construction Co

The fact that matters most here sits on the state registry: McCarthy Construction's Massachusetts home improvement contractor registration, number 156061, is expired. In Massachusetts that registration is what gives a homeowner access to the Guaranty Fund and the state arbitration programme if a job goes wrong, so its lapse changes what you would be signing up for. The rest is thin. One Google review, posted in 2022, calls them "a great group of guys" with "great work ethics" — warm, but with nothing in it about an actual job. That single five-star rating is all there is. Based at 8 Great Western Rd in Harwich, this is a Cape Cod general contractor. Before going further, ask directly whether the registration has been renewed, check it yourself with the Office of Consumer Affairs and Business Regulation, and ask for two recent local jobs you can go and look at.
