Thankfully, with a few quick steps, most windows can be repaired in just a matter of minutes. Use the list below to help you find both the problem and the solution.

Check the obvious
Before proceeding with the steps below, please double check for all the most obvious causes of why a window won’t open: are there any locks that need to be removed, is the window screwed shut, are you opening the window the correct way, or is anything blocking the window’s track? If not, then proceed.
Check for paint
If your window frame has recently been repainted, there is a chance that the paint is acting like a “glue” and holding the frame in place. If this is the case, then use a razor blade or putty knife to cut through the seal. Be thorough as you go — you’d be surprised how much holding force paint has.
Use a lubricant
Grab some WD40 or some sort of silicone spray. Remember, you’ll need to get it into the stuck section of window track as much as possible to see effective results. Keep some paper towels handy for clean up. For a really stuck window, spray both the inside and outside. Keep in mind that you may need to give the lubricant time to work.
Grab a rubber mallet
If the window still won’t budge, grab a rubber mallet and lightly tap the window sash and frame. Remember, your windows are made of glass, and that glass will break — be gentle. The tapping isn’t meant to force the window open, but rather to gently work it open.
If your window is really stubborn, grab a hammer and a putty knife or a pull bar (which is used to install laminate flooring). Use the putty knife or pull bar to try to get more leverage to force the window open. Please note, using this method could result in damage to the window or your drywall, so this is a last resort only.
Hopefully, these tips will help you with your stuck window dilemma. If you are not comfortable with doing the steps provided above, it is better to have a professional do the task to prevent further damage.
