How to Fix a Stuck or Jammed Window
A stuck window can be a major safety threat in the event of a fire. Depending on the window product (wood, vinyl, or aluminum), the fix varies.

If the wood has swollen due to humidity, wait on drier weather, then carefully tap a wood block against the sash with a hammer to loosen it. Sand down any high areas and apply paste wax to the tracks.
For Sliding and Vinyl Windows:
- The Culprit: Dirt, grit, or a misaligned track.
- The Fix: Vacuum the tracks thoroughly. Scrub away persistent grime utilizing a tooth brush dipped in a mix of warm water and mild dish soap.
