The sash stops must be removed and a thin strip of wood that is used to hold the sash. Also, remove any painted-covered hardware. Pull the sash to reveal the balancing weight, which is a heavy iron cylinder or lead that is enclosed in a hidden cavity and held by a rope. To keep the sash from falling into the void, make a hole in it using nails and remove the weight.

When the sashes are untied, clean out the jamb and meet rails, remove the glazing bars and sash cords and remove any paint off the sash stops using a utility knife. Reattach the stops after the sashes are reinstalled. Use nails that are not large enough to puncture the weight of the balancing.
