What affects the price
When you look at the price of impact windows, several factors shift the final number. The size and quantity of your window openings are the biggest drivers, as is the specific style—like single-hung, casement, or sliding doors. You will also see price differences based on the type of glass coating you choose for energy efficiency and the thickness of the aluminum or vinyl frames. Added hardware features or custom finishes can also adjust the bottom line. Homeowners typically see projects start in the mid-range of a few thousand dollars, but exact pricing is confirmed free on the call.
About this service
When budgeting for storm protection, consider the labor involved in removing old frames and sealing new ones to code. Custom sizes or specialized tinting will also change the final cost compared to off-the-shelf options.
Summer heat makes the energy-efficient benefits of impact windows immediately noticeable. High-quality glass reduces heat gain, which helps your air conditioning run more efficiently during the hottest months. While summer is a busy time for installations, getting your project on the books means you can stop fighting the heat and keep your home cool and quiet.
