A casement window is a lovely feature to add to your home. If you already have casement windows, you will be aware of the many benefits of them. You will also be aware that if they refuse to shut, they can cause serious issues. If you own a casement window that will not close, here is how you can fix it.

Step 1 – Take the Window off

Remove the hinge screws from the casement window and take off the side that will not shut. Examine the other side for any defects which could explain why it is causing problems. Check the hinges on the other window (that is still attached) and make sure none have come loose and caused sagging.

Step 2 – Check the Removed Window

Some casement windows close in together and join neatly over a butt joint. Other types of casement window have a separator bar down the middle so that each window closes on to it and not each other. Depending on the style you have, your issue could be the window or the separator. Examine the separator for defects. If you find none, check the window and make sure the hinges are all straight.

Step 3 – Plane

If you need to plane a little off the edge of a window to help it close then take the absolute minimum required. If the casement window is wood, it may have expanded owing to wet weather conditions and will eventually close normally again. Don't take so much off that it will cause a fissure between the windows or the window and the separator.
