Sash Weights

If your windows aren't closing and opening smoothly or are sluggish in a stuck position, a malfunctioning counterbalancing system could be the reason. This could be due to an ailing or damaged sash chain or a loose or misaligned sashweight, or a broken or cracked pulley.

The sash weights are small boxes made of cast iron, that serve to support the sash as well as help balance the counter-weight system of the window. They are located in the bottom rails of each window frame, and are covered by an access panel made of wood that can be removed to reveal their whereabouts. These panels can also be removed to gain access to the pockets of sash weights to clean, repair or replacement.

If you've used sash windows for a period of time, you may have an issue with the sash weights that cause them to lean or catch. This can be caused by the weights being too heavy (they are supposed to be a bit heavier than the top sash) or because they were installed incorrectly (some users have disabled their weight systems by cutting them off and taking them off to save money or turning them into scrap metal).
