If the hinges on a window begin to sag this could cause the sash to drag and eventually hit against the frame at the opposite corner (Photo 1). To remedy the issue ensure that the sash is aligned in the frame opening, and then take it off. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Install the new sash next (Photo 3).
Windows that are old, especially in older houses, can be difficult to open and close because of sagging hinges and general lack of energy efficiency. In many cases, a few simple fixes can make these windows operate smoothly once more and help homeowners save money on energy bills.
It is essential to have the tools you need before you begin. Mark the hinge channel's location on the frame (Photo 1) with a pencil.

Sash Weights
If your window sash repairs are to replace a damaged cord or to ensure that the windows are functional, replacing worn out weights for sash will improve its operation and reduce energy costs. Sash weights are heavy, lead or iron cylinders, which are enclosed in a hidden cavity and connected to the movable the sash with a rope. They function as counterbalances, allowing you to open and close the window without requiring mechanical or electrical devices. When they fail, sashweights are often neglected or not used by homeowners.

Older windows made of wood are joined using mortise and tenon joints. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. The majority of them are large on one side, and smaller on the other. It is crucial to remove first the smaller diameter sides. Sashes made later in the century used glue instead of pegs and can be separated by cutting through the glue line using a knife, then tapping the mortised part loose with a mallet.
After the sash is removed, you can remove the stopper on the sash and get access to the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is surrounded by an unfinished wooden panel that can be removed to reveal the interior workings.
After the sash has been stopped and the access panel removed, you'll be able to remove the weight of the old sash and replace it with the new. Weigh the sash first to ensure that the weights you've got may not be the right size. Once the new weight is installed then tie a string to it and thread it through the sash pulley. Then, attach the string to the boxed frame. Leave a few inches of space at the end of the string to allow future adjustments.
Sash Cords
In the majority of double-hung windows the chain or cord is connected to the weights. window repairs supports and keeps the sashes within the jamb in a balanced manner. Over time, these chains can become damaged and render it impossible to raise windows. A new sash cord will restore the ability to move the sash up and down and keep it in place when it is opened.

They are typically wedged into or nailed, but they can be removed, so it's worth taking your time here. If the sash remains in place, remove the mortise and tenon joints with the help of a hammer and pin or screwdriver, then remove the wood pegs attached to each component. It should now be possible to move the sash back and forth freely, though it might require oil if it feels stiff.
With the sash in an open position With the sash in an open position, measure the sash chain or cord to reach from the pulley at the top of the jamb to the sash slot at the bottom.
