Step 1 : Remove the sashes
Use a pry bar to remove the parting bead that holds the sashes in place.
If the window has layers of paint you may need a wide putty knife and hammer to separate the parting bead from the window frame. Carefully remove the two sashes and store them in a safe place.
Step 2 : Clean up the window frame
Scrape off any loose paint and sand the surface smooth. Cut the sash cord and let the sash weight pull them through. Back out the screw or nail at the top of the sash-weight door. Then remove the door and take out the sash weights.
Remove the screws that hold the sash weight pulleys and pry the pulleys from the jamb using a screwdriver. Fill the holes in the weight cavity with scraps of fiberglass insulation.
Step 3 : Scrape the window frame
Scrape off any loose paint or rough surfaces so the surface of the window jamb is smooth.
