Sash Weights

If your windows are not opening and closing smoothly, or are stuck, a faulty counterbalancing system could be the cause. This could be due to an ailing or damaged sash chain or a loose or misaligned sashweight, or a broken or damaged pulley.

The sashweights are small, rounded boxes made of cast-iron, which balance the counter-weight system and support the sash. 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 position. The panels can be removed for access to the sash-weight pockets in order to clean or repair them, or even replace window sashes them.

If you've used sash windows for a period of time, you may have a problem with the weights on the sash that cause them to sag or catch. The weights could be too heavy (they should be a little heavier than the top sash) or they've been installed improperly.

To address this issue, first take off the stops (the trim along the inside edges of the window that joins the frame and keeps it in place) and then set them aside. It is important to do this gently so as not to harm the shape of the two rails. Then, you can employ a hammer to break the rails and stiles, and check them for damage.

After examining the rails and stiles of the sash, put some dust sheets on the floor and begin working. Begin by taking the wood pegs out of the mortise and tenon joints using a pin punch and a screwdriver or hammer. After the pegs have been removed then you can begin to disassemble the sash by removing the sash stop moldings as well as removing any sash cord knots attached and, finally, removing the sash itself.

Sash Cords

The majority of sash window problems result from worn or broken sash cords. The weights put constant pressure on the sash cords and this could cause them to break over time. If cords break, sashes will not be able to open and close easily. The problem may be caused by excessive force, ageing or a lack of maintenance or the buildup of moisture. When you repair windows, it's important to replace the old cords with new ones made of a material that will last and resist moisture.

Begin by removing the inner stop strips, thin wood strips that hold the sashes into the frame, using a utility blade and a the chisel. Carefully pry the stops off of the sashes, keeping an eye out for any that are cracked or broken. After removing the stops, you can access the sashweights by opening the jamb or removing the weight pocket.

Accessing the sash cords takes some extra effort but it's not a problem with the right tools and perseverance. Remove the old cords first by cutting them in their knots and then pulling them out. Take the sash off and set it aside. When the sash is removed and you have pulled it down, grab the staff bead (the nail that keeps the sash from falling) and then insert one nail that is about one foot long into the hole in the staff bead. This will hold the sash in place while you finish stringing counterweights.

After reinstalling the upper sash then reattach the sash cords and make sure the sashes are in a balanced position and move smoothly. Reinstall the lower sash window replacement and repeat the process. Make sure that the sashes are properly set and are moving smoothly.
