    are they painted shut? If so sharp blade to cut the seal.
  • What type of windows are they? I would try WD 40. Just make sure they have not been painted shut from the outside.

    I'm only experienced with wood windows, not the metal-edged kind. If the windows have been painted shut, use a razor blade or utility knife to carefully cut through the paint at the crack between the window frame and woodwork (the part of the frame attached to the wall).

    Then, on the outside if possible, put a stiff scraper (the kind that looks like a putty knife) between the window frame and window sill and pry it up. Keep moving the scraper to different places so you'll be prying the window open evenly on both sides. You can tap the scraper handle with a mallet or hammer (lightly!) if you need to make it go under the window. You may have to loosen the window all the way around before you can move it.

    It works best to do this when it's dry weather and not humid. Of course, painted shut windows are good for sealing out drafts and saving on air conditioning.

    A small car jack and a couple of bits of wood will force the bottom sash up if they are wooden sash and case windows.
    Do this after you have taken a craft knife round and cut the paint seal.
    Do not try to lift your hands and arms and try to force them open.......

    is there a metal channel on the sides of the window? If so try a tiny squirt of a lube like w d 40...or similar product

    if the window are natural wood and have no been sealed they can swell with the humidity. are there springs or weights the ropes may have given out. If you can see a metal channel on the interior of the windows give it a shot of a a silicone spray lube.
