If the window sash on your Primed Gliding Window, manufactured from 1940 to 1971, is sliding hard, we recommend adjusting the window sash for smoother operation and better overall performance.

How to Adjust a Sash on Primed Gliding Windows

Adjustments can be made to the two (2) parts of the window, called front and back glides. The glides are nestled in the bottom of the windowpane's frame, and if their tightness is not the same, it can make your window look crooked when it is open or cause difficult operation.

To improve how your primed gliding window sash opens and closes, adjusting the glides can be done in a few quick steps that are outlined below.

Let's Get Started

Check Operation

Before adjusting the window sash, you will want to determine which glide in the bottom of the windowpane should be adjusted.

1. Open the window sash by about 1 inch.
2. Check to make sure the gap between the windowpane and side jamb, or side of the window frame, is the same at the top and bottom of the window.
   • If the gap between the windowpane and window frame looks crooked or the window is not sliding as it should, proceed to the next steps to adjust your gliding window sash.

Adjust Your Gliding Window Sash

If the windowpane seems crooked or your window is not sliding properly, follow the steps below.

1. Slide the window sash to the middle of the frame.
2. Lift the window sash, pulling the bottom of the window sash toward you inside of the home.
3. Inspect the bottom of the window sash and look for two (2) glides.
4. Use a flat blade screwdriver to adjust either the front or back glide up or down so the window sash is square in its frame.
• Note: A counterclockwise turn will shift the windowpane up, and a clockwise turn will shift the windowpane down.

Insert Top of the Window into the Frame

5. Return the window sash to the frame by inserting the top of the window into the top of the frame and situating the bottom of the window sash onto the sill.
6. Follow Check Operation steps one (1) and two (2) to see if the window is still crooked or not smoothly operating.
7. We recommend adjusting the glides again if the window is still not operating properly.

If the above adjustment to the glides on your window sash did not resolve the concern, Contact Andersen® Windows and Doors for further assistance.
