Sash Weights

If your windows aren't opening and closing smoothly or are sticking the way they should, a malfunctioning counter-balancing system could be at fault. This can occur due to a damaged or damaged chain/sash cord as well as a misaligned or unattached sash weight, or a broken pulley.

The sash weights are tiny boxes, typically made of cast iron, that help support the sash and also support the counter-weight system in the window. They are located at the bottom of every window frame. They are covered by an unfinished wooden panel that can be removed to reveal their position. The panels can also be removed to gain access to the sash weight pockets for cleaning, repairs or replacement.

If you've used sash secondary glazing windows for a period of time you likely have a problem with the sash weights, which cause them to sag or catch. The weights may be too heavy (they should be slightly heavier than top sash) or they've been installed in a way that isn't correct.

To address this issue, first pry off the stops (the trim that runs along the inside edges of the window where it meets the frame and keeps it in the frame) and then set them aside. This will require you to be gentle in order to not damage the shape of your meeting rails. You can then use a hammer or mallet to break the stiles and rails and examine the rails for damage or any repairs that need to be made.

Start by removing wood pegs with a pin-punch and a screwdriver or hammer from the mortise and tenon joints. Once the pegs are removed then you can begin disassembling the sash by removing the stop moldings for sash and removing the sash cord knots that are connected, and then taking the sash off itself.

During window sash repairs, it's important to replace the old cords with new ones that are made of an material that lasts and resist moisture.

Start by removing the internal stop strips, thin wood strips that hold the sashes into place, using a utility blade and a chisel.

After removing the stops, you can get access to the sashweights by opening up the jamb or taking out the weight pocket.

It takes a little extra effort to reach the sash cords but with the right tools and a bit of patience it is not difficult. Remove the old cords first by cutting them in knots, and then pulling them out. Remove the sash and place it aside. After the sash has been removed and you have pulled it down, grab the staff bead (the nail that keeps the sash from falling) and insert the nail, which is about a foot long into the staff bead hole. This will stop the sash from falling as you string the counterweights.

After reinstalling the upper sash, reattach the sash cords and make sure the sashes are balanced and move smoothly. Then, install the lower sash, and repeat the process, ensuring that the sashes are correctly seated and 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 on the sash. Repeat the procedure for each side of the sash until all cords are replaced and the sashes are functioning normally.
