Range Builders was founded through collaboration. Nic Altamura and Jeff Harold merged their established companies to create a firm with an ethos rooted in design-driven projects that emphasize detail and close collaboration throughout the lifecycle of a project.

As second-generation builders, Nic and Jeff approach construction with complementary backgrounds. Nic has honed his craft through decades of fine finish carpentry, while Jeff has built his expertise with a degree in Construction Management and experience in high profile Project Management. This melding of complementary skill sets ensures refined craftsmanship and meticulous project oversight throughout the building process.

At Range Builders, we pride ourselves on integrating the latest advancements in building science, project management, and quality craftsmanship into every project. Our boutique approach ensures a personalized and attentive experience for our clients.

Proudly serving the Marin, Napa and Sonoma County.
