What is the process for sash cord replacement in windows?

The process for sash cord replacement in Windows involves removing the window sash, detaching the old cord, attaching a new cord, and re-installing the sash. This is typically done by accessing the weights inside the window frame, removing the sash, and replacing the cords that connect the sash to the weights. Once the new cords are in place, the sash can be re-installed and the window should operate smoothly.
