Why Fort Collins Homeowners Choose Weatherguard

Fort Collins experiences the full range of Colorado's challenging climate conditions. From frigid winter temperatures and driving snow to summer heat and intense UV exposure, your windows must perform year-round. Weatherguard understands these local conditions and specifies window solutions engineered for Colorado's climate zone.

Our Fort Collins service team brings decades of combined experience in residential window replacement. Every project begins with a thorough in-home assessment where we evaluate your existing windows, discuss your priorities—whether energy savings, noise reduction, aesthetics, or all three—and provide a detailed, transparent estimate with no hidden costs or surprise fees.

Window Styles Popular in Fort Collins

Homes in Fort Collins range from classic Colonial and Craftsman styles to modern contemporary builds. We install every major window type including double-hung, casement, bay, bow, picture, sliding, awning, and specialty shapes. Our design consultants help match the right window style to your home's architecture and your personal preferences.

Energy Efficiency for Colorado Climate

ENERGY STAR certification in the Northern climate zone requires a U-factor of 0.30 or lower. All windows installed by Weatherguard in Fort Collins meet or exceed this standard. We recommend triple-pane glass packages with low-E coatings and argon or krypton gas fills for maximum performance in Colorado's heating-dominated climate.

Homeowners in Fort Collins who replace single-pane windows with ENERGY STAR certified units can expect annual energy savings of $126-$465, depending on home size and current heating system efficiency. The federal Inflation Reduction Act provides a 30% tax credit up to $600 for qualifying window installations.
