If the hinge arms of a window begin to sag, this can cause the sash to slide and eventually land on the frame in the corner that's opposite the hinge arm (Photo 1). To address this issue, first make sure the sash fits squarely in the frame's opening and then take it out of the window. If the sash is screwed onto the hinge arm, unbolt the hinge and replace it.

The majority of them have an enormous diameter on one side and a smaller size on the other, so it is important to remove the smaller-diameter ones first. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallets.

Once the sash is freed then you can take out the sash stop and gain access to the weight pocket. This is typically done by drilling an opening at the bottom of every jamb. The hole is surrounded by a wooden panel that can be removed to reveal the interior workings.
