Choose your city
Colorado's climate presents unique demands for windows, including intense UV radiation, significant diurnal temperature variations, and cold winters. Homes in Aurora and Thornton, often built with various architectural styles, benefit from windows that provide excellent insulation and UV protection. Older windows can lead to substantial heat loss during cold months and heat gain during sunny days, increasing HVAC usage. Upgrading to double-pane, low-E coated windows with argon gas fill is essential for minimizing energy transfer, lowering heating and cooling costs, and protecting interior furnishings from sun damage.
Common questions

Who is Andersen Windows' biggest competitor in Colorado?
Colorado's market features many window manufacturers. Our company prioritizes providing expert installation and high-performance windows for homeowners in Aurora and across the state. We focus on delivering durable solutions tailored to Colorado's climate.
Is it cheaper to replace your own windows in Colorado?
While DIY installation might seem cost-effective, improper window replacement in Colorado can lead to problems like air leaks and poor insulation, especially with the significant temperature shifts. Professional installation ensures a proper seal, optimal energy efficiency, and the longevity of your investment.
What time of year are windows the cheapest to replace in Colorado?
Window replacement costs in Colorado can sometimes be more favorable during the off-peak seasons, such as late fall or winter, when demand may be lower. However, the consistent benefits of improved energy efficiency and comfort throughout Colorado's varied climate often make the upgrade itself more critical than timing for minor savings.
Does Colorado have specific permitting for window replacement?
Many standard window replacement projects in Colorado, including in Thornton, do not require individual permits unless structural changes are involved. We ensure all work is performed in accordance with local building codes for your assurance.
