Sash Weights
If your windows are not closing and opening smoothly, or are stuck the way they should, a defective counterbalancing system could be the cause. This can be caused by a damaged or missing sash chain or a sashweight that is not aligned properly or not attached to a the sashweight, or even a broken or cracked pulley.
The sash weights are small boxes, typically made of cast iron that help support the sash and also help balance the counter-weight system of the window. They are found in the bottom rails of each window frame and are covered with a wooden access panel which can be opened to reveal their position. The panels can be removed to gain access to the sash weight pockets to clean, repair or replacement.
There could be an issue with the sashweights if you've had your windows with sash windows for long enough. They could lean or catch. This could be due to the weights being too heavy (they are supposed to be a bit heavier than the top sash) or due to them being installed in a way that isn't correct (some users have disabled their weight systems by cutting them and removing the weights to save money, or turning them in for scrap metal).
To fix this issue, first take off the stops (the trim that runs along the inside edges of the window that joins the frame and keeps it in place) and then set them aside. This will require you to be gentle so as to not damage the appearance of your overlapping rails. You can then make use of a mallet or hammer to break up the rail and stiles and inspect the rails for damage or any repairs that need to be done.

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

Pry the stops from the sashes with care and be on the lookout for any cracked or broken ones. After removing the stops, you can get access to the sashweights by opening up the jamb or taking out the weight pocket.

First, remove the old cords by cutting them close to their knots and then pulling them out. Take the sash off and set it aside. Remove the staff bead. This is the nail that keeps the sash in place. Install the nail about a foot into the hole. This will stop the sash from falling while you finish stringing the counterweights.
After installing the upper sash again then reattach the sash cords and ensure that the sashes are properly balanced and move smoothly. Then, reinstall the lower sash, and repeat the process, making sure that the sashes are seated and moving smoothly.
After you've installed counterweights, connect the sash cords by putting a sash cord through the pulleys and then threading the cord's other end through a knot hole inside the sash to secure it in the correct position. Repeat the procedure for each side of the sash until the cords are replaced and the sashes function normally again.

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