How To Adjust A Casement Window Sash

| 24 July 2017

Casement windows are some of the most popular window designs on new homes, as well as one of the most popular upgrades to older homes. Casement window installation is best left to the professionals, who will not only be able to provide the best installation possible, but be able to give you some important information on adjusting the casement window sash when you need to. Below are some things to keep in mind when adjusting a casement window sash.

 Adjusting Casement Window Sashes

Fixing a Stripped Crank Handle

If you are turning your window handle and it is not opening or closing, the gears on the handle crank have probably been stripped away. The first thing to do is to remove the handle and inspect it for signs of wear and tear. If the teeth have worn away, you will need to replace the handle (which you can get from various manufacturers, even home and garden stores), or you can contact your casement window installation professionals. If the shaft is worn, you will need to replace the entire operator.

Sticky Windows

If your window is dragging against the frame as you open it, you will need to close it and inspect it from the outside to know where and how to make the adjustments. The sash needs to fit squarely and be centred directly in the middle of the frame.

If you need to make an adjustment to the position of the sash, you can do this by slightly repositioning the hinge channel. You can remove the channel at either the top or the bottom of the window (but not both). You can then gently remove the sash and mark the area of the frame where you want the sash to go. Fill the old hole with a waterproof epoxy and then drill ⅛” point holes over the mark that you have made on the frame.

Call in the Experts

When it doubt, the best thing to do if you require adjustments to your casement windows is to call in the experts. Improperly moving or adjusting your windows can do an incredible amount of damage to the frame and the working parts of the window itself, and it can end up costing you more money that it would have been to have someone come in and do it right the first time.

Casement windows are a bit more tricky than other windows because of their mechanical nature. Over time, the constant winding and unwinding of the window can end up wearing the bearings and gears out, and you might need to either attempt a readjustment yourself, or call casement window installation experts in to give you a hand.
