Sash Hardware

To correct the issue, make sure that the sash is centered in the frame opening and then remove it. If the sash is screwed to the hinge arm, you'll need to remove the hinge arm and replace it (Photo 2). Then, put in the new sash (Photo 3).

Old windows, especially those in older homes, can be difficult to open and close due to hinges that are sagging and general inefficiency. In most cases, a few simple repairs can transform these windows into smooth operators and save homeowners cash on energy costs.

It is crucial to have the tools needed before you begin. Begin by marking the position of the hinge channel on the frame using a pencil (Photo 1). This will help you get the channel back into place correctly when you're finished.

Sash Weights

If your window sash repairs are to replace a broken cord or just to keep the windows functional, replacing worn out weights on sash can improve sash operation and reduce the energy cost. Sash weights consist of heavy lead or iron cylindricals that are contained inside a concealed cavity, and attached by ropes to the movable Window Repair sash. These weights provide counterbalance which allows the window repair to be closed and opened without the need for mechanical or electrical devices. When they fail, sashweights are usually ignored 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 fits properly. You will also require an additional piece of string, a length of sash cord and some sash pulleys to tie the new sash weights onto the sash cord.

Mortise and Tenon joints can be used to join older wood windows. Hammers and pins can be used to cut off the wood pegs that hold the parts together. The majority of them have an enormous diameter on one side and a smaller one on the other side, so it is crucial to take out the small-diameter sides first. Sashes that were made later in the century used glue instead of pegs. They can be separated by cutting through the glue line using an instrument, and then tapping the mortised section loose with mallets.

Once the sash is freed, you can remove the sash stop and access the weight pocket. Usually, this is done through an opening in the bottom of each jamb. The hole is then covered with an access panel made of wood which can be removed so that you can observe the inner workings of the frame.

After the sash has been stopped and the access panel removed, you will be able to remove the old sash weight and replace it with the new. Be sure to weigh the sash first because the weights you've got may not be the correct size. Once the new weight is installed, tie a string to it and then thread it through the sash pulley. Then, nail the string to the boxed frame. Leave a few inches protruding at the end of the string to allow future adjustments.

Sash Cords

Most old double-hung windows include a chain or cord attached to the weights which keeps the sashes level within the jamb. As time passes, these cords may break, making it impossible to raise the window. A new sash cord will restore the ability to move the sash up and down and keep it in place when opened.

Once the access panel is removed, you can begin working on the sash. Make the small parting beads (also called "tie rails") out of their grooves with a chisel or flat bar. They are usually wedged in or nailed but can be snipped out which is why it's worth your time. If the sash is still in place, break the mortise and the tenon joints by using the help of a hammer and pin or screwdriver, then unhook the wood pegs that are on each piece. The sash should be able move freely now, but it may require some lubrication in order to feel less stiff.

Determine the length of sash cord/chain required to reach the sash slot at the bottom, and the pulley located at the top of the jamb. Cut the cord or chain and secure it as in Step 6 above. You can employ a hammer, nail or screws, but nails are less likely to cause damage.

It is recommended to keep the weights that came with the original counterbalance unless you've purchased a kit that will replace the counterbalance.
