Remove the sash from the frame and pull it to the right until it is completely open. Cut the cord in the middle of the sash and remove any nails sticking out of the end. With needle-nosed pliers, take out the nail and insert it into the side channel. The knot of the cord should be tucked into the hole and secure it with a nail set.

Re-install the sash and then install the staff beads. Be sure to leave plenty of space on the cords to ensure the proper operation. Reinstall the balances and counterweights. Decorators caulk is a great method to minimize draughts. Apply small amounts of caulk between the staff bead box.

Remove the staff bead which is what separates the upper and lower sashes. You can take the bead off using needle-nose pliers. A nail is inserted through the knot and into the casing of the sash window locks to secure it. Remove any nails that are rusty from the stop beads, and then clean off any paint, caulk and old cord residue around the groove in the sash.

To open the windows, pull one of the cords that run through the sash. Once you've pulled it as far as it will go make a mark on the cord using pencil, and then cut it into length with a knife. After you've finished, ensure that the new cord lines up with the groove of the sash and is connected to the frame by a knot.

Take the one on the back and the one on the front, and then tie each sash cord to a weight by using self-tightening knot.

Weights are pushed across a system of pulleys to counterbalance the weight of windows with sash. These weights are typically cast iron and can be accessed from an access panel or pocket cover located within the lining of the box of the window frame. To stop the weights from falling down, an dividing strip is hung within the frame to ensure that they do not collide.

It isn't easy to get these weights out, since the sash's upper part can be sprayed shut and fixed with nails.
