Built by
Brothers.
A family-owned construction company rooted in Martha's Vineyard — building homes, businesses, and lasting relationships since 2018.
From a Shared
Vision
Guimarães Brothers Construction was born from a simple idea: that the buildings people live and work in deserve the care of someone who treats every project like it's their own.
What started as two brothers swinging hammers on Martha's Vineyard has grown into a trusted name across the island — but our values haven't changed. We still answer the phone ourselves. We still walk every job site. We still take pride in every nail.
Today, our team handles everything from custom homes and additions to commercial buildouts, roofing, finish work, and landscaping. Whatever the scope, the standard stays the same.
Our Values
Craftsmanship
Details done right the first time, with premium materials and a steady hand.
Family First
Founded by brothers, run like a family. Every client is treated like one too.
Trust
Honest communication, transparent pricing, and accountability from start to finish.
Community
Proud to build for our neighbors across Martha's Vineyard, year after year.
The Brothers
Two brothers, one shared standard. On every job site, every day.
Leads project planning, client relationships, and on-site coordination. Believes the best work comes from listening first and building second.
Heads field operations and craftsmanship standards. A decade of hands-on experience framing, finishing, and finishing again until it's right.
