Build

With an intimate knowledge of environmental regulations, permitting, and the Cape’s unique ecosystem, we are uniquely poised to move client projects through often complex regulations and hurdles. Once plans are approved, our decades of construction expertise allow us to manage projects with great efficiency while providing clients with the highest quality of workmanship.

Renovations

Over the years, we have renovated everything from contemporary to historic houses, and understand the necessity of maintaining a home’s character while upgrading it to modern standards. We are fluent in the detailed permitting processes throughout the Cape and the building procedures needed to properly renovate established homes.

Property Services

Many clients are here to enjoy their time on the Cape and don’t wish to spend hours on property maintenance. Others live here seasonally and want their home looked after during the off-season. For those homeowners, we provide a full slate of property management services customized to your specific needs. In a nutshell, our services are designed to relieve you of the burden of property maintenance while providing peace of mind.

Hear What Our Clients Have to Say

They came by and listened to what we were looking for, understood the restrictions we were facing due to wetlands and within a few weeks came back to us with ideas that we could have never dreamed of. Not only did they show us rough ideas of their thoughts but they spent so much time taking us to other projects they had done to make their ideas come alive.

After researching many building options I chose deMartin Dunham Builders. From the first time I met them they listened to my ideas, my needs and never once told me that I couldn’t have what I wanted. It is hard to find a builder that sits and listens, talks through problems, includes you in on all decisions of your project. I never once felt they didn’t understand me.

I have nothing but good things to say! These guys are second to none when it comes to home renovating or new build. Their true craftsmanship is impeccable. You can tell they have pride in what they do. Very communicative and transparent. I would highly recommend to anyone.
