Sash weights are composed of iron or lead cylinders that are encased inside a concealed cavity, and connected by ropes to the moveable window sash. These weights act as counterbalances and allow you to open and shut the window without requiring mechanical or electrical devices. The sash weights are often disregarded or disabled by homeowners, and are turned into scrap when they break; therefore you might need 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 is suitable for the. You will also need an additional piece of string, a length of sash cord, and a few sash pulleys to tie the new sash weights to the sash cord.

The majority of these pegs have large diameters on one side and a smaller one on the other, which is why it is essential to remove the small-diameter sides first. Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised area loose with mallets.

Be sure to weigh the sash before you do this, as the weights that were previously used may be different sizes than the one you need. After the new weight is in place you can tie a string around it and then thread it through the pulley of the sash. Then, nail the string to your boxed frame. Leave a few inches of space at the end of the string for future adjustments.

Sash Cords

In most old double-hung window, a chain or cord is attached to the weights. This supports and keeps the sashes in the jamb in a balanced manner.

After the access panel has been removed, you can start working on the sash. Prise the narrow parting beads (also called "tie rails") out of their grooves using flat bar or chisel. These are often wedged in or nailed in, but they can be prised free, so it's worth taking your time. If the sash is still in place, pry the mortise-and-tenon joints out using a hammer or screwdriver, then remove each wood peg. You should be able to move the sash around freely, although it will probably need some oil if it feels stiff.

Take a measurement of the length of sash chain/sash cord required to reach the sash slot at the bottom of 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, nails, or screws. However nails are less likely to cause damage.
