Remove the sash stops (a thin vertical strip of wood that supports the sash) and then loosen any paint-encrusted hardware. Pull the sash back to reveal the weight. It is a massive iron or lead cylinder that is concealed inside a cavity and supported by a cord. To prevent the sash falling into the void pierce it using a nail, and then sacrifice the weight.

After the sashes are removed, clean the jambs and the rails that meet. Remove the glazing bars and cords for the sash. Then, using a utility blade take off any paint from the sash stop.
