Sash Weights
When windows aren't opening or closing smoothly or are sticking, a faulty counter-balancing system could be the cause. This could be due to a damaged or damaged sash chain or cord or an unattached or misaligned sash weight, or a broken pulley.
The sash weights are tiny boxes made of cast iron that help support the sash and also support the counter-weight system in the window.

Get rid of the old cords first by cutting them in their knots and then pulling them out. Then, you can remove the sash from the frame and set it aside.
