Last updated: September 24, 2026

What affects the price

The final price for impact windows depends on several variables specific to your home. The biggest factors include the total number of openings you need to cover, the style of the windows, and the specific glass thickness required for your local building codes. Opting for specialized frame materials or custom sizes will naturally push your investment higher compared to standard configurations. Additionally, the complexity of the installation process—such as the condition of your existing frames or the height of your home—plays a major role in the budget. We focus on matching the right hardware to your structural needs.
