Impact Window Replacement

Replacement is a full-house envelope decision. Angi says installing impact windows throughout a house with an average of 22 windows is $15,400 to $63,250. A South Florida dealer guide says a retrofit into existing frames costs less than a full-frame replacement, and that structural repairs add $200 to $800 per opening, most often in homes built before 1990.

Why does Angi talk about replacing every window?

Angi says if you’re going to install impact windows, you should ideally replace every window in your house with an impact window, and that a single broken window during a hurricane can destabilize the pressure in your home.
