Window jamming or rubbing: Adjust the window properly

Do it yourself

Curved windows: Use this trick to solve the problem

If the window is blocked and not closed properly, rain can get in and damage the seal. Well-adjusted windows save on heating costs. So check your windows regularly.

An annual inspection ensures that a window opens easily and always closes tightly. You should take action at the latest when the window can only be opened with a jerk or you have to lift the window sash to close it. Re-adjustment is necessary if the handle can no longer be placed in the correct position or the window does not close properly and drafts enter.

If the window won’t close properly and is blocked, you can readjust it properly with just a few simple steps. For this you will need an Allen key and a flat key.

If the window sash rubs or pinches at the top or bottom, first remove the cover caps on the bottom corner pads. The corner pad is located at the bottom of the side of the window opposite the handle.

The window sash is dragged down: Use an Allen key to turn the screw on the corner bearing clockwise several times to the right to raise the window sash.

The window sash is dragged up: Use the Allen key to turn counterclockwise to the left. The window sash is then lowered.

The window sash is only stuck in one corner: In this case you have to make adjustments to the scissor bearings. The scissor bearing (also scissor fitting) is located at the top of the side of the window opposite the handle. Here turn the screw clockwise with an Allen key. Thus, the window sash is lifted to one side.

The window sash blocks or drags to the side: If the window sash is pulling to the side, open the window first. Then use the Allen key to adjust the upper and lower corner bearings and turn the screws clockwise.

If the sash seal does not press against the frame or the window is difficult to lock, then you should increase the contact pressure. To do this, take an Allen key or a Phillips or slot screwdriver and adjust the locking pin. The locking pin (also locking pin or mushroom pin) is located on the side of the window handle.
