Use a disposable N100-rated respirator mask, disposable coveralls, shoe covers, and a painter's hat when working with paint in older homes to prevent lead paint inhalation and exposure.

Steps
1
Inspect the window to determine if it is painted shut or if the wood has swelled due to moisture. If in a damp climate, try running a dehumidifier in the room for 24 hours to see if the sash loosens.
2
Run a utility knife along all the joints that surround the sash to cut through dried paint. Ensure you address the rear side of the top edge, using a step stool if necessary.
3
Attempt to open the window. If it opens, rub a stub of a candle or a bar of soap along the channel where the sash travels to lubricate the area and prevent future sticking.
4
If the window remains stuck, remove the interior stops by taking out the screws with a Phillips #2 screwdriver and carefully prying the stop molding free from the lower sash using a putty knife.
5
Remove the parting strips. If they are painted shut, score the joints with a utility knife before pulling them out carefully.
6
Remove both the upper and lower sashes from the frame. Inspect the sashes for dampness or swelling; if wood is swelled, contact a professional to check for missing or poorly installed exterior flashing.
7
If no water damage is found, scrape and sand the sashes down to bare wood using medium-grit sandpaper. Apply a coat of primer and a fresh coat of paint, ensuring there is no build-up in the channels.
8
Once the paint is completely dry, reassemble the window by placing the sashes back into the frame and reattaching the interior stops.
Pro Tips
When painting sashes, be careful not to leave areas of paint buildup, as this is the primary cause of windows becoming stuck.
