The sash weights are often disregarded or disabled by homeowners and then turned into scrap when they fail; therefore you may have to find replacements.

It's not easy to retrieve the sash-weight that fell from the cavity, so you'll need to find one that fits properly. You will also require a new piece of string, a length of sashcord and some sashpulleys to tie the weights you are replacing to the cord.

Later sashes utilized glue instead of pins. They can be cut by using a knife and a mallet.
