What is the difference between full-frame and insert (pocket) replacement?

An insert, or pocket, replacement fits a new window inside your existing frame, which works well when the old frame is still solid. Full-frame replacement removes the entire window down to the rough opening, which is the right move when there is rot, water damage, or you want to change the size or style. During the consultation, we look at the actual frames and tell you honestly which approach your home needs.
