Remove the screen on the existing window so that you can accurately measure how big the hole will be after the window is removed. Measure the length and width in more than one location on the window to ensure the numbers are correct. Take the measurements to a home improvement center to purchase a replacement aluminum window with the proper dimensions.

Cut the meeting rail with a reciprocating saw or remove the screws attaching it if possible. The meeting rail is the length of aluminum that separates the fixed and movable panes of glass; some are horizontal and some are vertical. The removal process is the same regardless of the orientation of the meeting rail.
