The sashweights are small, rounded boxes made of cast-iron, which balance the counter-weight system as well as support the sash. They are situated in the bottom rails of every window frame, covered by an access panel made of wood that can be removed to reveal their whereabouts. The panels can be removed to gain access to the weight pockets in the sash to clean, repair or replacement.

If you've used sash windows for a period of time you likely have a problem with sash weights that cause them to lean or catch. The weights can be too heavy (they should be a little heavier than the top sash), or installed incorrectly.

To fix this problem, remove the stops (the trim that runs along the inside edge of the window where it meets the frame to hold it in place). Place them aside. You'll need to do this slowly so as not to harm the appearance of the overlapping rails. Then, you can employ a hammer to break the rails and stiles, and inspect them for damage.

After removing the stops, you can access the sashweights by opening the jamb or removing the weight pocket.

Remove the staff bead, which is the nail that keeps the sash in place. Insert the nail about a foot in length into the hole. This will temporarily keep the sash from falling as you finish stringing the counterweights.

After reinstalling the upper sash and sash window locks cords, reconnect them and ensure that the sashes are balanced and move smoothly. Reinstall the lower double glazed sash windows for listed buildings, and repeat the process. Make sure that the sashes have been properly set and are moving smoothly.

After you've installed the counterweights, reattach the sash cords by putting an sash cord into the pulleys, and then threading the cord's other end through a knot hole inside the sash to secure it in place. Repeat this process for both sides of the sash, making sure that the sashes function normally again.
