Impact Window Replacement

Per Angi, installing impact windows throughout a house with an average of 22 windows is expensive: $15,400 to $63,250. Per Armor Pro, a retrofit installation into existing frames costs less than a full-frame replacement where the entire frame is removed and rebuilt, and structural repairs add $200 to $800 per opening, most often in homes built before 1990.
