Impact windows average cost — Boulder, CO

Last updated: September 24, 2026

What affects the price

Replacing your windows with impact-rated glass involves a few variables that shift your final total. First, the size and number of openings in your home play the biggest role, as custom measurements require more material and labor. The style of window you choose—like single-hung, casement, or sliders—also changes the math, as does the frame material, such as vinyl versus aluminum. If you live in an area with stricter wind-load requirements, that might necessitate thicker glass or specialized hardware.

About this service

While every home is different, the average cost for an impact window project varies based on the number of openings and the chosen frame materials. You should expect the price to shift if you need impact-rated sliding doors or custom glass shapes. Exact pricing confirmed free on the call.

Summer heat is intense, and impact windows act as a powerful barrier against thermal transfer. By blocking solar heat gain, your air conditioning system doesn't have to work as hard, which helps keep your energy costs manageable. Getting your windows replaced now provides a cool, quiet environment inside, regardless of how high the temperature climbs outside your home.
