Sash Weights
If your windows aren't opening and closing in a smooth manner or are sticking, a faulty counter-balancing system could be the cause. This could be due to a damaged or damaged chain/sash cord, an unattached or misaligned sash weight, or a damaged pulley.
The sashweights are small, rounded boxes made of cast iron that support the counter-weight system and support the sash. They are situated in the bottom rails of every window frame, and are covered by a wooden access panel that can be cut open to reveal their whereabouts. These panels can be removed for access to the sash weight pockets to clean, repair or replace them.
If you've been using sash windows for a long time you likely have a problem with the weights on the sash that cause them to lean or catch. The weights can 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 problem, first pull off the stops (the trim along the inside edges of the window where it joins the frame and holds it in the frame) and then set them aside. This will require you to be gentle so as to not harm the appearance of your overlapping rails. Then, you can make use of a mallet or hammer to break the stiles and rails and check them for damage or any repairs that require to be done.
After you've examined the rails and stiles, lay down dust sheets and begin working on the sash itself. Start by taking the wood pegs out of the mortise and tenon joints using a pin punch and a hammer or screwdriver. After the pegs have been removed you can begin to disassemble the sash by taking out the sash stop moldings as well as removing any sash cord knots still connected, and then taking the sash off itself.
The next step is to weigh the sash in order to determine how much weight it needs for proper functioning. You can find old weights for sash replacement online or at a few home improvement stores, but you should be sure to purchase 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 can cause them to break over time, especially when they're not maintained properly. 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 accumulation of moisture. It is crucial to replace the old cords during window sash repair with new cords made of materials that are robust and resistant to moisture.
Start by removing the internal stop strips, the thin wood strips that hold the sashes in their place Utilizing a utility blade and a the chisel. Remove the stops off the sashes carefully, and keep an eye out for any broken or cracked ones. After the stops have been removed, you can access the sash weights through an access panel cut into the bottom of the frame or by opening the jamb and removing the cover for the weight pocket.
It may take a bit more effort to reach the sash cords, but with the right tools and a bit of patience, it's not difficult. First, remove the old cords by cutting them near their knots and then pulling them out. Take the sash off and set it aside. Once the sash is off then pull it back down on the staff bead (the nail that prevents the sash from falling) and insert a nail about a foot long into the staff bead hole. This will keep the sash in place as you string counterweights.
Reattach the sash strings after reinstalling upper sash. Verify that the sashes move in a smooth manner and are in a balanced position. Then, you can reinstall the lower sash, and repeat the process, making sure that the sashes are correctly sitting and moving smoothly.
After you've installed the counterweights, reconnect the sash cords by putting a sash cord through the pulleys and then threading the other end of the cord through a knot hole inside the sash to secure it in the correct position. Repeat this procedure on each side of the sash, making sure that the sashes function as they should again.
Air leaks and drafts
Over time, materials that seal your sash window to the frame of your house begin to deteriorate. This can cause drafts and energy loss.

Examine the sash's connection to the frame including the parting beads and staff bead. Check the condition of weather stripping at these points (felt strips or tape) to determine if they are intact and working. If not, it needs to be replaced.
Take a look at the condition of the glazing putty. This is a hard putty used to keep panes of tempered glass in place. Check for cracks or crumbling that exposes the sash's surface to moisture which could cause mold issues and even damage the windows' glass.
To fix the problem, apply a layer of fresh glazing putty onto the inside of your window. Using a flat-blade screwdriver, push the glazing points into place to hold them. Wrap a piece of fabric and then foam around each point. This acts as an insulation against cold air.
