If the hinge arms of a window are starting to sag, this can cause the sash to slide and eventually hit the frame in the corner that's opposite the hinge arm (Photo 1). To address this issue, first make sure the sash is squarely inserted into the opening of the frame and then remove it from the window. If the sash was attached to the hinge arm, take it off the hinge and replace it. (Photo 2). Install the new sash next (Photo 3).

Sash Weights
Sash weights can be changed to improve the performance of your window sash and reduce the energy cost. Sash weights are heavy, lead or iron cylinders that are enclosed in a hidden cavity and attached to the movable sash by a rope. These weights act as counterbalances and allow you to open and shut the window without having to use mechanical or electrical devices. The sash weights are often neglected or ignored by homeowners, and are turned into scrap when they fail; therefore, you may need to search for replacements.
It is difficult to recover the sash-weight that fell from the cavity, so you'll need to find one that fits correctly. You will also require an additional piece of string, a length of the sash cord, as well as some sash pulleys to connect the new sash weights the sash cord.
Mortise and Tenon joints can be used to join older wood windows. The wood pegs that hold the components together can be removed by the use of a pin punch and hammer. The majority of them have an enormous diameter on one side and a smaller size on the other, which is why it is essential to remove the small-diameter sides first. Sashes that were made later in the century made use of glue instead of pegs. They can be separated by cutting through the glue line with a knife, then tapping the mortised part loose with a mallet.
After the sash is removed and removed, you can take off the sash stop and gain access to the weight pocket. Usually, this is done through an opening at the bottom of each jamb. The hole is then covered with an unfinished wooden panel that can be removed to reveal the inside workings.

After their website is installed, tie a string to it and then thread it through the pulley of the sash. Then, you can nail the string to the frame, leaving a few inches of string hanging from the head for future adjustments.
Sash Cords
In the majority of old double-hung windows, a chain or cord is affixed to the weights. This keeps the sashes within the jamb balanced. Over time, these cords can become damaged and make it difficult to raise the windows. A new sash cord will restore the ability to move the sash up and down and will keep it in its position when it is opened.
The first step in replacing cords for sash is to locate and take out the access panels located in the jambs. They are usually screwed or nailed in and must be removed. It may be possible to remove them with the hammer or chisel but it is always best to lay out dust sheets prior to beginning any work.
After you have removed the access panel, you are able to begin to work on the sash. Take the narrow beads (also called "tie rails") out of their grooves with flat bar or chisel. These are often wedged in or nailed but can be removed which is why it's worth your time here. If the sash remains in place, pry the mortise and tenon joints free with a hammer or screwdriver, then remove each wood peg.
