They function as counterbalances and allow you to open and close the window without having to use mechanical or electrical devices. The sash-weights are typically ignored or discarded by homeowners and turned into scrap when they break; therefore you may have to locate replacements.

A weight in a sash that has fallen out of the cavity is difficult to retrieve and you'll need to find a new one that fits properly. You will also require a new piece of string, a length of the sash cord, as well as some sash pulleys that will tie the new sash weights to the sash cord.

Mortise and Tenon joints are used to join older wood windows. Pin punch and hammer can be used to take out the wood pegs holding the parts together. The majority of these pegs are big on one side, and smaller on the other. It is important to first remove the smaller diameter sides. Later sashes utilized glue instead of pins. They can be separated by using a knife and mallet.

After the sash has been removed then you can take out the stopper on the sash and get access to the weight pocket. This is usually done via tiny holes at the bottom of each jamb.

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 they can be prised free and it's worth your time here. If the sash remains in place, break the mortise-and-tenon joints out using a hammer or screwdriver and then take out each wood peg. The sash should be able move freely, however it may require some lubrication to feel less stiff.

Determine the length of sash chain/sash cord required to reach the sash slot on the bottom from the pulley at the top of the jamb. Cut the cord/chain and then attach it in the previous step. You can do this with nail, hammer or screws. However nails are less likely than screws to cause damage.
