Sash Weights
When windows aren't opening and closing smoothly or are sticking the way they should, a malfunctioning counter-balancing system could be at fault. This could be due to an ailing or damaged sash chain or a sashweight that is not aligned properly or not attached to a weight, or a damaged or damaged pulley.
The sash weights are small 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 rails of every window frame. They are covered with an unfinished wooden panel that can be removed to reveal their position. The panels can be removed for access to the sash-weight pockets in order to clean and repair or replace them.

Sash Cords
Sash cords that are worn or broken can lead to sash window issues.

It is crucial to replace the old cords in window sash repair with new cords made of an material that is strong and resistant to moisture.

Pry the stops off the sashes carefully, and keep an eye out for any broken or cracked ones. After removing the stops you can gain access to the sashweights by opening the jamb or removing the weight pocket.
It requires a bit of effort to reach the sash cords but with the right tools and a bit of patience it is not difficult. First, you must remove the old cords by cutting them near their knots and then pulling them out. Remove the sash and set it aside. Remove the staff bead, the nail that holds the sash in place. Insert a nail of about a foot length into the hole. This will hold the sash in place as you string counterweights.
Reattach sash window repairs following reinstalling upper sash. Check that the sashes move in a smooth manner and are balanced. Then, install the lower sash and repeat the process, making sure that the sashes are correctly in place and are moving smoothly.
After you've installed counterweights, connect the sash cords by putting the sash cord through the pulleys and then threading the other end of the cord through a knot hole in the sash to secure it into place. Repeat this process on the opposite side of the sash, making sure that the sashes function as they should again.

Then, think about the condition of glazing putty, a hard putty that keeps panes of glass in place. Look for cracks or crumbling that expose the sash to moisture which could cause mold problems and damage the glass of windows.

These can be removed with a blade that is attached to a small pry-bar or a putty knife. They are typically fixed in place and painted, so be careful not to harm them or the sliding sash.
After you've removed your parting beads, the next task is to take off the covers for your pockets. These are bits of wood in the frame, low down, that give access to the weights for the sash and are typically attached with nails. They could also be glued with paint, so you have to be careful.
