Expert Window & Door Replacement in Fort Collins and Beyond
Renewal by Andersen serves Fort Collins homeowners with deep expertise in northern Colorado's unique climate challenges and architectural heritage. Our local knowledge spans from Victorian-era homes in Old Town to contemporary developments throughout the region, ensuring every installation complements your home's character while addressing Fort Collins' specific environmental demands. The city's semi-arid climate, with only 16 inches of annual precipitation and 237 sunny days per year, creates intense UV exposure and dramatic temperature fluctuations that can compromise inferior windows and doors. Our exclusive Fibrex® material windows and expertly crafted doors are specifically engineered to withstand these conditions while reducing dust infiltration—a common concern in Fort Collins' dry climate. Whether your home sits along the Cache La Poudre River corridor or enjoys foothills views toward Horsetooth Reservoir, our Certified Master Installers understand local building codes, including Fort Collins' enhanced 2018 IECC requirements, and ensure every installation meets the highest standards for energy efficiency and long-term performance. We proudly serve Fort Collins and surrounding communities including Loveland, Windsor, Berthoud, and throughout Larimer County.
