Sash Weights

If windows aren't opening and closing smoothly or are sticking the way they should, a malfunctioning counter-balancing system may be to blame. This can occur due to a missing or damaged sash chain or cord, an unattached or misaligned sash weight, or a broken pulley.

The sashweights are tiny boxes made of cast iron that support the counter-weight system and support the sash window restoration. They are situated in the bottom rails of each window frame, covered by an access panel of wood that can be cut open to reveal their position. These panels can be removed for access to the weight pockets in the sash for cleaning, repairs or replacement.
