This issue can be caused by a variety of things, such as insufficient maintenance or an incorrect weight rating for a particular sash.

If the hinges on windows begin to slide, this could cause the sash to drag and eventually hit against the frame in the opposite corner (Photo 1). To correct the issue make sure the sash is in the proper position within the frame's opening and remove it. If the sash has been screwed to the hinge arm, you'll need to loosen the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

They provide counterbalance which allows the window to be opened and closed without the use of electrical or mechanical devices. The sash weights are usually disregarded or disabled by homeowners and window repairs then turned into scrap when they fail; therefore you may have to search for replacements.

Be sure to weigh the sash first, as the weights you've got may not be the right size. Once the new weight has been installed, you can thread the string through the sash pulling mechanism. Then attach the string to the frame, leaving a few inches of string sticking out from the head for future adjustment.

Sash Cords
