If your casement window won’t open, won’t close, or just clicks and spins when you turn the handle, don’t assume the window is finished.
This is one of the most common (and most misunderstood) window problems we see.
In most cases, only the window crank needs to be replaced — not the entire window.
At Mr Cranky, we specialize in window crank replacement for casement windows, saving homeowners hundreds (sometimes thousands) of dollars compared to full window replacement.
When Does a Window Crank Need Replacing?
Window crank operators wear out over time — especially on older windows or windows that have been forced when they were stiff or out of alignment.
You likely need a new window crank if:
-
The handle spins or clicks but the window doesn’t move
-
The window only opens partway or won’t close fully
-
Gears inside the crank are worn or stripped
-
The crank arm is bent, broken, or disconnected
-
Splines on the crank stud are worn or missing
If the window can still be pushed open and closed by hand, that’s a strong sign the window itself is fine — the crank has simply failed.
Not Sure If It’s the Crank or the Hinges?
Good question — and this is where experience matters.
Before replacing anything, we check:
-
Whether the window opens and closes smoothly by hand
-
If the hinges are bent, seized, or out of alignment
-
Whether the crank failed because something else caused resistance
Replacing a crank without fixing the underlying issue can cause the new part to fail again.
We fix the cause — not just the symptom.
