How It Started

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.

What We Stand For
