If the hinge arms of a window are starting to lose their elasticity, this could cause the sash to slide and eventually strike the frame in the corner that's directly opposite the hinge arm (Photo 1). To correct the issue make sure the sash is in the proper position within the frame opening and then take it off. If the sash was screwed onto the hinge arm, remove the hinge and replace it.

Sash weights are heavy, lead or iron cylinders enclosed in a concealed cavity and linked to the moveable the sash with rope. They provide counterbalance which allows the window to be opened and closed without the need for mechanical or electrical devices. When they fail, sashweights are often left unnoticed or disabled by homeowners.
A weight in a sash that has fallen out of the cavity is difficult to recover and you'll need to find a new one that is suitable for the. You will also require a new piece of string, a length sash cord and some sash pulleys to connect the new sash weights onto the sash cord.
Older wood windows are joined using mortise and tenon joints. The wood pegs that keep the parts together can be removed by a pin punch and hammer. The majority of these pegs have an enormous diameter on one side and a smaller diameter on the other, so it is crucial to take out the small-diameter sides first. Later sashes used glue instead of pins. They can be cut by using a knife or mallets.
Once the sash has been removed, you can take off the stops on the sash and get access to the weight pockets. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with a wooden access panel that can be ripped off to allow you to see the inner workings of the frame.

They are typically wedged into or nailed in, but they can be prised free which is why it's worth your time here. If the sash is still in place, pull the mortise-and-tenon joints out using a hammer or screwdriver and then remove each wood peg.
