Sash Weights
If your windows aren't closing and opening smoothly or are sluggish the way they should, a defective counterbalancing system could be the cause. It could be caused by a damaged or missing sash chain or a loose or misaligned sashweight, or a broken or damaged pulley.
The sashweights are tiny boxes made of cast iron that support the counter-weight system and support the sash. They are situated in the bottom rails of each window frame and are covered with an access panel made of wood which can be opened to reveal their location. The panels can be removed for access to the pockets of sash weights to clean, repair or replacement.
If you've had sash windows for some time you likely have a problem with weights on the sash that cause them to sag or catch. The weights could be too heavy (they should be slightly heavier than top sash), or installed improperly.
To address this issue, first pry off the stops (the trim that runs along the inside edges of the window that joins the frame and holds it in the frame) and then set them aside. It is important to do this slowly so as not to damage the shape of the two rails. Then you can use a hammer or mallet to break the rail and stiles and examine them for damage or for any repairs that need to be done.
Once you've inspected the stiles and rails lay down some dust sheets and begin working on the sash itself. Begin by removing the wood pegs from the mortise and tenon joints using pin punches and a screwdriver or hammer. After removing the pegs you can begin disassembling the sash. Remove the stop moldings for sash and any sash cords that are still attached.
Next you will want to weigh the sash and figure out how much weight is required for the proper functioning. You can buy vintage replacement sashweights on the internet or at some home improvement stores. Make sure you get the right size to avoid over - or under-weighing the sash.
Sash Cords
Sash cords that are worn or broken can cause problems with the sash window. The weights exert constant pressure on the sash's cords which can cause them to break over time. The sashes will not open or close as easily when the cords break. The issue could be caused due to excessive force, aging, lack of maintenance, or the buildup of moisture. In repairmywindowsanddoors of window sash repairs it is essential to replace the old cords with new ones that are made from materials that last and resist moisture.
Begin by removing the inner stop strips, thin wood strips which hold the sashes in place with a utility knife and a the chisel. Carefully pry the stops off of the sashes, keeping an eye out for cracks or broken. After the stops have been removed, you will be able to access the sash weights through an access panel that is cut into the frame's bottom, or by opening the jamb and removing the weight pocket cover.
It may take a bit more effort to reach the sash cords but with the proper tools and a bit of patience, it's not difficult. First, take off the old cords by cutting them close to their knots and then pulling them out. Then, you can remove the sash from the frame and set it aside. Once the sash is off, pull down on the staff bead (the nail that keeps the sash from falling) and then insert one nail that is about a foot long into the staff bead hole. This will keep the sash on its place while you finish stringing counterweights.
After reinstalling the upper sash then reattach the sash cords and make sure the sashes are properly balanced and move smoothly. Reinstall the lower sash and repeat the process. Verify that the sashes have been properly seated and are moving smoothly.
After you've installed the counterweights, reconnect the sash cords by placing an sash cord into the pulleys and threading the other end of the cord through a knot hole inside the sash, ensuring it is secured in the correct position. Repeat this process on both sides of the sash, making sure that the sashes function normally again.
