If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to drag and eventually hit the frame in the corner that's in the opposite direction of the hinge arm (Photo 1). To fix this issue, first make sure the sash is squarely inserted into the frame's opening and then remove it from the window. If the sash is screwed onto the hinge arm, take it off the hinge and replace it. (Photo 2). Then, you can install the new sash (Photo 3).

Due to hinges that are sagging, and a general deficiency in energy efficiency, older windows particularly those in older houses, could be difficult to open or close.

Sash Weights

Whether your window sash repairs are to replace a damaged cord or just to ensure that the windows are functional by replacing worn out weights on sash can improve sash operation and reduce energy consumption. Sash weights are made of heavy lead or iron cylinders that are encased inside a concealed cavity, and connected by a rope to the movable window sash. These weights provide counterbalance that allows the window to be shut and opened without the use of electrical or mechanical devices. When they fail, sashweights tend to be ignored or disabled by homeowners.

It's difficult to retrieve a sash-weight that has fallen from the cavity, so you'll want to find one that fits correctly. You will also require a fresh piece of string, a length sashcord and some sashpulleys to tie the new weights to the cord.

Mortise and Tenon joints can be used to join older wood windows. The wood pegs holding the parts together can be removed by pin punches and hammers. Most of them have large diameters on one side and a smaller one on the other, so it is important to remove the small-diameter sides first. Later sashes made use of glue instead of pins. They can be separated with a knife and mallet.

After the sash is removed, you can remove the sash stop and gain access to the weight pocket. This is typically done by drilling an opening at the bottom of every jamb. This hole is then covered by an access panel made of wood which can be removed to let you view the inside of the frame.

Sash Cords

Over time these cords can break, making it impossible to raise the window. A new sash cord can restore the ability to move the sash upwards and downwards and will keep it in its position when it is opened.

After you have removed the access panel, you can begin working on the sash. Take the narrow beads (also called "tie rails") out of their grooves with a chisel or flat bar. They are usually wedged in or nailed in, but they can be snipped out, so it's worth taking your time here. If the sash remains in place, pry out the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, and then take out the wood pegs that are on each component.
