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?
