If the hinge arms of a window are beginning to lose their elasticity, this could cause the sash to slide and eventually land on the frame in the corner opposite the hinge arm (Photo 1). To address this problem, first ensure that the sash is firmly seated in the opening of the frame and then take it out of the window. If the sash was attached to the hinge arm, unbolt the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).
Windows that are old, especially in older houses, can be difficult to close and open due to sagging hinges and an overall lack of energy efficiency. Sometimes it is a matter of making a few minor adjustments that can allow these windows to operate smoothly once more and help homeowners save money on energy costs.

Sash Weights
Whether your window sash repairs are to replace a damaged cord or to keep your windows functioning and functional, replacing worn-out weights on sash can improve sash operation and help reduce the energy cost. Sash weights are composed of heavy iron or lead cylinders that are enclosed in a hidden cavity and attached by a rope to the movable window sash. These weights function as counterbalances, allowing you to open and close the window without the need for mechanical or electrical devices. The sash-weights are typically disregarded or disabled by homeowners, and are turned into scrap when they fail. Consequently you may have to find replacements.
A weight from a sash that fell out of the cavity is difficult to retrieve, so you will want to find a new one that is suitable for the. You will also need a new piece of string, a length of sash cord, and a few sash pulleys that will tie the new sash weights onto the sash cord.
Older wood windows are joined by mortise and tenon joints. The wood pegs that hold the parts together can be removed using pin punches and hammers. The majority of these pegs have large diameters on one side and a smaller one on the other side, so it is important to remove the smaller-diameter sides first. Later sashes utilized glue instead of pins. They can be separated by using a knife or mallet.
After the sash is released, you can remove the stops on the sash and get access to the pockets for weights. Usually this is accomplished by drilling a hole near the bottom of each jamb. This hole is covered by an access panel made of wood that can be cut off to let you view the inside of the frame.
After the sash has been stopped and the access panel has been removed, you are able to remove the old weight and replace it. First, weigh the sash, as the weights you have may not be the correct size. After the new weight is installed, run the string through the sash pulling mechanism. Then nail the string to the boxed frame, but leave a few inches of string hanging from the head to allow for future adjustments.
Sash Cords
In the majority of double-hung windows, a chain or cord is connected to the weights. This keeps the sashes of the jamb in a balanced manner. Over time, these cords could break, making it difficult to raise the window. A new sash cable will restore the ability to move and lower the sash and keep it in position when opened.

It's important to be patient, as these are often stuck or nailed to the floor. If the sash is still in place, break the mortise and the tenon joints by using a hammer and pin punch or screwdriver, then unhook the wood pegs attached to each component. The sash should move around freely now, however it may need some lubrication to feel less stiff.
With the sash open Take a measurement of the sash chain to extend from the pulley in the top of the jamb to the sash slot at the bottom. Cut the cord/chain and then fix it as described in Step 6 above. You can use either nail, hammer or screws. However, nails are less likely to cause damage.
