Remove the sash stops (a thin vertical strip of wood that holds the sash) and loosen any painted-covered hardware. Reverse the sash to reveal the weight. It is a heavy iron or lead cylinder that is hidden in a cavity and is held by cords. To stop the sash falling into the void pierce it with a nail and sacrifice the weight.
Once the sashes are free clean the jamb and rails that meet, remove the glazing bars and sash cords, and remove any paint from the sash stops using an utility knife. After the sashes have been put returned to their original positions, you can attach the stops using nails that are not too large to risk puncturing the weight that is balancing.
