Sash Weights

If windows aren't opening or closing with ease or are sagging, a faulty counter-balancing system may be to blame. This can be caused by the sash being damaged or missing chain or a loose or misaligned the sashweight, or even a broken or damaged pulley.

The sashweights are small boxes made of cast-iron, which balance the counter-weight system and support the sash. The sash weights are situated at the bottom rails of every window frame. They are covered by wood panels that can be removed to reveal their location. These panels can be removed for access to the sash weight pockets to clean, repair or replacement.

You may have an issue with the sashweights if you've had your windows with sash windows for over a period of time. They could lean or catch. This could be due to the weights being too heavy (they are supposed to be slightly heavier than the top sash) or due to them being installed incorrectly (some people disabled their weight systems by cutting them and removing the weights to save money, or turning them in for scrap metal).

To correct this problem, first pull off the stops (the trim that runs along the inside edges of the window that joins the frame and keeps it in place) and set them aside. You'll need to do this slowly so as not to harm the shape of the two rails. Then, you can employ a hammer to break the stiles and rails and then inspect them for damage.

Start by removing the wood pegs from the mortise and tenon joints with a pin punch and a screwdriver or hammer.

Sash Cords

Most sash window issues stem from broken or worn sash cords. The weights exert constant pressure on the sash cords and this could cause them to break over time. If the cords break, the sashes won't be able to open and close easily. The problem can be caused by a number of factors that can cause it, such as excessive force, aging, a lack of maintenance, and the accumulation of moisture. When you repair windows, it's important to replace the old cords with new ones that are made from materials that last and resist moisture.

Start by removing the interior stop strips, thin wood strips which hold the sashes in place with a utility knife and a chisel. Take care to remove the stops 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 taking out the weight pocket.

First, remove the old cords by cutting them close to their knots and pulling them free. Remove the sash and set it aside. Once the sash is off and you have pulled it down, grab the staff bead (the nail that keeps the sash from falling) and insert a nail about a foot long into the hole for the staff bead. This will temporarily keep the sash from falling as you finish stringing the counterweights.

After installing the upper sash, reattach the sash cords and make sure the sashes are in a balanced position and move smoothly. Then, you can reinstall the lower sash and repeat the process, ensuring that the sashes are correctly sitting and moving smoothly.

Reattach the sash cables once you have put in the counterweights. Thread the cord through the pulleys, and then through the knot hole on the sash. Repeat the procedure for each side of the sash until all cords have been replaced and the sashes are operating normally.
