Pocket Window Installation Prices
Pocket installation, sometimes referred to as insert installs, is the easiest and cheapest way to replace your existing windows. Pocket installation can only be done on an existing replacement window, not on a new construction window that has a nailing fin attached to it. (In the case of a new construction window, the existing window will have to be cut out of the frame and a replacement or retrofit window would be installed in its place.)
In the case of a pocket installation, the existing replacement window is removed from the opening and the new replacement window is slid in, where it is made square and plum using wooden shims that hold it in place. The window is then secured into place using predrilled screw holes in the frame. A low expanding foam fills any gaps between the frame and opening, and then the window is caulked and sealed in place. Consumers can expect pocket installation to run $50 to $75 per window.
