Window Sash Repairs

Sash Weights
If your windows are not opening and closing with ease, or are stuck, a faulty counterbalancing system could be the cause. This could be because of a broken or damaged sash chain or cord or an unattached or misaligned sash weight, or a 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 on the bottom rails of every window frame. They are covered with an unfinished wooden panel that can be removed to reveal their location. These panels can also be removed to gain access to the pockets of sash weights for cleaning, repairs or replacement.
If you've had sash windows for some time you likely have a problem with the weights on the sash that cause them to lean or catch. The weights could be too heavy (they should be a little heavier than the top sash), or installed in a way that isn't correct.
To address this issue, first pry off the stops (the trim 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 appearance of the overlapping rails. Then you can employ a mallet or hammer to break the rail and stiles and examine the rails for damage or any repairs that require to be made.
Once you've inspected the stiles and rails lay down dust sheets and start working on the sash itself. Start by removing wood pegs with a pin-punch and a hammer or screwdriver from the mortise and tenon joints. Once the pegs are removed you can begin disassembling the sash by removing the stop moldings for sash, pulling off any sash cord knots still in place, and finally, taking the sash off itself.
The next step is to weigh the sash and determine how much weight is required for the proper functioning. You can find old weights for replacement on the internet or at some home improvement stores, but you should be sure to buy the correct size so as not to under or over weigh the sash.
Sash Cords
Often sash window problems stem from worn or broken sash cords. Sash cords are under constant pressure from the weights, which could cause them to break over time, particularly if they're not properly maintained. The sashes won't be able to open or close as easily if cords break. The problem could be caused by a variety of things like excessive force, aging, the lack of maintenance or accumulation of moisture. It's important that you replace the old cords in window sash repair by new ones made of a material that is strong and resistant to moisture.
Begin by removing the inner stops, the thin pieces of wood that keep the sashes in place with a utility knife and a Chisel. Pry the stops from the sashes with care, and keep an eye out for any cracked or broken ones. After removing the stops, you can get access to the sashweights by opening 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's not difficult. First, you must remove the old cords by cutting them near their knots, and then pulling them away. Then, you can remove the sash from the frame and set it aside. When the sash is removed then pull it back down on the staff bead (the nail that prevents the sash from falling) and insert the nail, which is about one foot long into the hole in the staff bead. This will keep the sash in place while you string counterweights.
After reinstalling the upper sash and sash cords, reconnect them and ensure that the sashes are properly balanced and move smoothly. Reinstall the lower sash, and repeat the procedure. Check that the sashes are properly set and are moving smoothly.
Reattach the sash cables once you have installed the counterweights. Thread the cord through the pulleys and then through the knot hole in the sash. Repeat this process for each side of the sash, making sure that the sashes work as intended again.

Consider the condition of glazing putty. This is a hard putty used to hold panes of tempered glass in place. Look for cracks and a crumbling surface that could expose the sash's exterior to moisture. This can lead to problems with mold and damage to the glass.
