Guimauto Construction

Guimauto Construction is a Hudson exterior outfit — siding, roofing, gutters, decks, windows and doors — and its Massachusetts home improvement contractor registration is active. It is a young company. The BBB puts its start date at June 2022, counts eight employees, and grades it A+ while noting it is not accredited. Its BuildZoom score of 90 sits at the 47th percentile of Massachusetts contractors, and the single permit on file there is a $21,000 job in Hanson in September 2025: siding, asphalt shingles, and 80 linear feet of gutters. Neither the BBB nor BuildZoom holds a customer review, so there is no written account from anyone who has actually hired them. The company tells its own story plainly. Tullio Guimaraes, a Brazilian entrepreneur, founded it after two years in U.S. construction and named it for his father Milton, who ran the original Guimauto in Brazil's automotive trade. Tullio leads operations, his wife Natalia is CFO, and the company describes itself as family-owned. It says it works across Massachusetts, New Hampshire and Rhode Island. If you are collecting quotes for siding, a roof, or gutters, this is a properly registered contractor with a real, if short, permit record. Ask for addresses of recent jobs you can drive past and for references you can call, since there is no public review history to lean on yet.
