Remove the chains and cords from both sides, and tie them in a way that they can't be pulled back by the weights attached. It's now time to remove the upper sash. Unscrew the sash stops (a thin vertical strip of wood that holds the sash) and then loosen any painted-covered hardware. Unscrew the sash to reveal the weight balancing, that is a massive lead or iron cylinder enclosed in a concealed cavity and secured by rope. To prevent the sash falling into the void, pierce it using a nail, and then let the weight go.
When the sashes are untied clean the jamb and rails that meet, remove the glazing cords and sash bars, and remove any paint from the sash stops with the help of a utility knife. When the sashes are returned to their original positions, you can attach the stops using nails that are small enough to prevent puncturing the balancing weight.
Reassemble the sash by putting the upper sash on top of its track, then the lower sash. Verify that the sash stoppers and the frame are aligned correctly. If needed, reconnect any beads used for parting. Reattach the sash chains or cords and install the sash pulleys.
