A sticky window is usually caused by one of two things: the sash has been painted shut, or the tracks are clogged with dirt. Both are common, and both can be fixed with simple tools in a short time. The first step is to work out which problem you have.
Try these fixes before you think about new replacement windows. In most cases you can get the window opening and closing smoothly again and enjoy the fresh air.
If the Window Is Painted Shut
A sloppy paint job is a frequent culprit, especially on older wood windows. When paint bridges the gap between the sash and the frame and dries, it glues the window in place.
If you can see paint across the joints, use a box cutter to carefully score all the way around the sash. Then slide a putty knife into the joint to break the seal, working your way around until the window opens. Go slowly so you do not gouge the frame or crack the glass.
If the Tracks Are Dirty
Window tracks collect dirt, dust and pollen. Over time that debris builds up until the sash drags or jams. Cleaning and lubricating the tracks should get the window working the way it should.
Clean Out the Debris
Open the window as far as you can. Wipe out loose debris with a dry cloth, then use the brush attachment on your vacuum to pick up what the cloth missed.
For caked-on dirt, mix a solution of vinegar and water. Wet a cloth with it and scrub the grime away.
Do not use bleach or abrasive cleaners. Even if some dirt seems impossible to remove, resist the urge to scrape it with a sharp metal tool or a razor blade, which can damage the window.
When the debris is gone, wipe the tracks with a clean wet cloth and dry them with a fresh towel.
Lubricate the Tracks
Use a silicone-based lubricant. Spray some onto a dry cloth and wipe it on the tracks, the jamb liner and the weatherstripping.
Open and close the window a few times. If it still sticks a bit, apply a little more until it moves without trouble.
Do not spray the lubricant directly at the window. Lubricant on the frame makes a mess, and on the glass it can leave a permanent mark.
When a Sticky Window Needs to Be Replaced
Sometimes a window sticks because it is old and damaged. Frames that have warped or swollen, broken hardware, or a sash that will not stay up are not problems cleaning can solve.
In that case, replacement is the practical answer. Aladdin installs vinyl replacement windows that are easy to operate and maintain, make your house more energy-efficient and improve its curb appeal.
