Bellwether Windows, Siding, & Doors

About Us

The Bellwether team has been serving Colorado homeowners for nearly four decades, bringing trusted experience to families throughout Conifer, Evergreen, Morrison, Bailey, and the surrounding foothills. Living in the mountains means facing unique challenges—snow, hail, wildfire risk, and intense sun—and we specialize in exterior remodeling solutions built to endure Colorado’s climate while protecting and enhancing your home.

As Colorado’s #1 James Hardie siding installer and a top Pella windows and doors contractor, we pair national expertise with a local, family-centered approach. Our noncombustible, fire-rated siding options give mountain homeowners peace of mind, while our custom designs, energy-efficient windows, and durable doors deliver beauty and performance.

We’re committed to transparent pricing, clear communication, and a stress-free process so you always know what to expect. Our mission is simple: help homeowners feel proud of where they live. Whether restoring a historic cabin, upgrading to fire-resistant siding, or designing a modern retreat, Bellwether is your trusted guide. We stand behind every project with industry-leading warranties and craftsmanship that lasts a lifetime.
