Learn MoreFive Years of Real New England Construction Experience
Magatão Construction was founded by Junior after more than five years of building, framing, decking, siding, and roofing across New England. Word-of-mouth referrals built the business — now we are bringing that same craftsmanship to homeowners across New Hampshire, Maine, and Massachusetts.
Every project we take is treated like it is going on our own home. That means dead-level frames, properly seated fasteners, and a finished job site you would not hesitate to walk barefoot.

Real Reviews from Real New England Homes
Word-of-mouth has carried Magatão Construction for five years. Here is what neighbors across NH, ME, and MA say about our work.
"Junior framed the addition on our colonial. Clean work, on schedule, and the inspector signed it off with zero corrections. We are using him again for the deck."
"Our new deck looks incredible and feels rock-solid. Magatão dug the footings deep, used real composite, and the railings are perfectly straight. Worth every dollar."
"Honest pricing, on-time, and they cleaned up the site every day. Hard to find that combination. Already recommended them to two neighbors."
