Remove any security fittings that are behind the lower window sash. Then, remove the staff bead, then remove the bottom sash. Then, remove the chains or cords on both sides and tie the ends to stop them from being pulled back into the frame by the attached weights. The next step is to remove the upper sash. Take out the sash stops and a thin strip of wood that is used to hold the sash. Also, remove any painted-covered hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away inside a cavity and secured by a cord. To stop the sash from falling into the void pierce it using a nail, and sacrifice the weight.

After the sashes have been removed clean the jambs and rails that connect them. Remove the glazing bars as well as the cords for the sash. Then employing a utility blade take off any paint from the sash stop. When the sashes are returned to their original positions, you can attach the stops using nails that are not too large to risk cutting the balancing weight.

Reassemble the sash by putting the upper sash first into its track, followed by the lower sash. Make sure that the sash stops are in the correct alignment with the frame, and then reattach the beads that separate if required. Then, reconnect the sash cords or chains and re-install the sash pulley axles.
