Get rid of the old cords first by cutting them in their knots and then pulling them out. Remove the sash and set it aside. After the sash has been removed, pull down on the staff bead (the nail that prevents the sash from falling) and then insert one nail that is about 1 foot into the hole in the staff bead. This will stop the sash from falling while you string the counterweights.
After installing the upper sash again and sash cords, reconnect them and ensure that the sashes are properly balanced and move smoothly. Reinstall the lower sash and repeat the process. Check that the sashes are properly seated and are moving in a smooth manner.
