How to Replace a Sliding Glass Window
- 1). Remove the screen by pulling it out of position from either the side or bottom. Slide the window so that it is halfway between its open and closed position. Hold the window halfway up on both sides, making sure that you have a good grip (wearing a good pair of work gloves will help). One hand will have to slide in between the stationary window and the sliding window.
- 2). Lift the sliding window up until its top hits the inside window frame. The bottom of the sliding window will now be free of the window frame. Pull out the bottom of the sliding window until it is free of the frame. Lower the sliding window (it will now be free of the frame) and place it to one side.
- 3). Clean any dirt that has accumulated in the frame, using a window cleaner and a rag. Lift up the new window frame with one hand halfway up on both sides. Push the top of the window up into the window frame (halfway between open and closed positions), while pushing the bottom of the window in over the window frame and into place. Lower the window: the bottom of the window will slide down into the window frame, and the sliding window will be in position. Slide the window from left to right, making sure it runs smoothly. Clean the window on both sides and replace the screen.
