- PossibleCorroded or worn crank/hinge hardwareCasement-style egress windows rely on cranks and hinges that can seize.
- PossibleDebris in the window well blocking the sash swingAn outward-opening egress window needs clearance in the well to fully open.
What to do
- Treat this as a priority repair since egress windows must open fully and easily for emergency exit.
- Score any paint seams and clear debris from the track or well.
- Apply penetrating oil to hinges or the crank mechanism and work it gently.
- Clear the window well of leaves, dirt, or debris that could block the sash from swinging open.
- Test that the window opens fully to its required clear opening size once freed, not just partially.
- Replace any worn or broken crank, hinge, or latch hardware rather than leaving it stiff.
- Recheck the window every few months, especially before winter, to make sure it still opens freely.

When to call a pro
Call a window repair company promptly if you can't get it fully operational yourself, since code requires it to open completely without tools.
Safety
Use caution
An egress window is a required emergency exit; don't leave it stuck, and prioritize this repair over cosmetic window issues.
