How Do You Loosen A Stuck Window Sash?
Window sashes can get stuck for a variety of reasons. Some are easy to correct, while others take a little more persuasion. Here’s how to remedy the situation. Check for nails or screws holding the window shut. A previous owner might have nailed the window shut for security reasons. Look carefully: If the nails or screws have been in place for a while, they may be painted over. Remove any nails or screws that you find. Inspect both the inside and outside of the frame to make sure the window isn’t painted shut. Loosen windows that are painted shut by running a sharp utility knife all around the edge of the window sash where it meets the jamb, both inside and outside. Use a blow-dryer or other mild heating device to reduce swelling if the sash is swollen from humidity. Install quality storm windows to regulate temperature and humidity changes and prevent future swelling.
