Sash Weights

If your windows are not closing and opening smoothly or are sluggish the way they should, a defective counterbalancing system could be at fault. This can occur because of a broken or damaged sash cord/chain or an unattached or misaligned sash secondary glazing weight, or a damaged pulley.

The sash weights are tiny boxes, usually constructed of cast iron that help support the sash and also support the counter-weight system in the window. They are located in the bottom rails of every window frame and are covered with a wooden access panel that can be cut open to reveal their whereabouts. These panels can be removed for access to the sash-weight pockets to clean, repair or replace them.

If you've had sash windows for some time you likely have a problem with the 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 improperly.

To remedy this issue, remove the stops (the trim that runs along the inside edge of the window at the point where it joins with the frame to keep it in place). Place them aside. It is important to do this gently so as not to harm the shape of the two rails.

First, take off the old cords by cutting them near their knots, and then pulling them away. Remove the sash and place it aside. Take off the staff bead. This is the nail that holds the sash in position. Put a nail of about a foot into the hole. This will stop the sash from slipping away while you string the counterweights.

Reattach the sash strings following installing the upper sash. Check that the sashes move in a smooth manner and are in a balanced position. Reinstall the lower sash and repeat the process. Verify that the sashes have been properly placed and are moving smoothly.

Reattach the sash cable after you have put in the counterweights. Thread the cord through the pulleys, and then through the knot hole in the sash. Repeat this process for both sides of the sash, making sure that the sashes function as they should again.
