About Us

Who We Are

Colorado Sash & Door, Inc., headquartered in Northern Colorado, specializes in window and door solutions for new construction and remodeling/replacement projects since 1991.

Successfully completing numerous projects throughout Colorado, Wyoming and Nebraska, Colorado Sash & Door, Inc. is preeminent within the historic restoration and commercial retrofit markets. Our products (wood, fiberglass, vinyl and aluminum) are also well suited to new construction projects focusing on energy efficiency and sustainability.

We are a resource for your construction team. We can help you design and develop detailed solutions, write specifications, provide budget pricing, prepare shop drawings and supply mock-ups. Our staff’s knowledge extends beyond windows to specialty mill-work, hardware, and construction techniques, expertly guiding you from product selection through final installation.

We look forward to working with you on your project!



Design Assistance

Our staff has the knowledge to walk you through product options, provide budgets, and design custom solutions for new construction, remodeling, and retrofit. 

We regularly consult with architects and commercial general contractors to provide specifications, drawings, installation advice, and preliminary budgets for projects.  

In-House Fabrication

When you want something truly original, our manufacturing capabilities allow us to build custom doors and window sashes and produce other components not readily available in the mass marketplace.

This flexibility means customers can choose the designs and materials that fit their priorities, and we can fabricate miscellaneous wood and metal components needed for installation.

Field Installation

Hire us to take your project from design through installation.

Our experienced staff will follow industry standards for installing our products to limit air infiltration, protect the structure from water leakage or condensation that can damage framing and walls, and reduce sound intrusion.
