how to unstick interior double-hung windows.?

Question

i'm currently painting my living room right now. i read on many home improvement websites that to paint double-hung windows you are supposed to first move the outter or top half of the window down and the bottom or inside half up. the trouble is that these windows are old and the top sash (half) of the window won't move down. the bottom one moves up and down fine however. can anyone tell me how i can unstick the top half of the window so i can move it down?? thanks!!

Answer 1

Cut all of the paint, and caulk around the edges of the sash, inside and outside. Use a sharp utility knife. Gently tap on it using a block of wood between the frame and hammer,(so you don't dent the wood).
After you get it unstuck, lubricate the tracks with candle wax.

Answer 2

Careful as you may have a single hung window that looks as if it is a double hung. Most times when a double hung window is paint-bound on the upper sash it is best to leave well enough alone. They seldom seat properly again and the innocent freeing of the upper sash snowballs into re-glazing or even worse replacing the window.

Answer 3

Maybe a little WD-40, or even a little cooking oil might help
