If the sash is double-hung, take out the weights using their ropes that should be buried within the jamb lining.

These weights provide counterbalance which allows the window to be opened and closed without the use of electrical or mechanical devices. The sash-weights are typically ignored or discarded by homeowners, and are turned into scrap when they fail. Consequently you might need to locate replacements.

A weight from a sash that fell out of the cavity is difficult to recover and you'll need to find a new one that fits properly. You will also require a new piece string, a length sashcord and a few sashpulleys for tying the weights you are replacing to the cord.

Mortise and Tenon joints can be used to join older wood windows. Pin punch and hammer can be used to cut off the wood pegs holding the parts together. Most of them have an enormous diameter on one side and a smaller diameter on the other, which is why it is essential to remove the smaller-diameter ones first. Later sashes made use of glue instead of pins. They can be separated by using a knife and a mallet.

Once the sash is freed and removed, you can take off the sash stop and gain access to the weight pocket. This is typically done by drilling an opening in the bottom of each jamb. This hole is covered by an access panel of wood which can be removed to allow you to observe the inner workings of the frame.

After the sash has been stopped and the access panel has been removed, you are able to remove the weight you used and replace it. Be sure to weigh the sash first, as the weights you've got may not be of the right size. After the new weight is installed you can tie a string around it and then thread it through the sash pulley. Then nail the string to the frame, but leave a few inches of string hanging from the head for future adjustment.

If the sash remains in place, break the mortise-and tenon joints with a hammer or screwdriver, then remove each wood peg. It should now be possible to move the sash back and forth without difficulty, though it might require oiling if it seems stiff.

Determine the length of the sash chain or sash cord required to reach the sash slot on the bottom from the pulley on the top of the jamb. Cut the chain or cord and secure it as in the previous step. You can use a hammer and screws or nails, however nails are less likely to cause damage.

It is best to keep the weights that came with the original counterbalance unless you have purchased a kit to replace the counterbalance that was previously installed.
