Home/Locks, Cranks and Hardware
Window hardware repairWindow Lock, Crank and Hardware Repair
A window that will not lock, a crank that spins without opening the window or a hinge that drags makes your home less secure and less comfortable. We replace broken locks, cranks, operators, handles and hinges with parts that fit your window.

Hardware we repair and replace
- Sash locks and keepers on double-hung windows
- Casement and awning cranks (operators)
- Stripped crank handles and gear boxes
- Hinges and stay arms on casement windows
- Tilt latches and pivot hardware
- Sliding window locks and rollers
- Window locks for added security
Casement windows that will not open
When a casement crank turns but the window does not move, or the handle spins freely, the operator gears are usually worn out. We replace the operator and, if needed, the hinges, so the window opens fully and closes tight against the weatherstripping.
Locks that do not latch
A sash lock that will not line up usually means the sash has shifted, the balance is worn or the keeper is loose. We fix the cause, not just the lock, so the window closes and locks easily. Better locks are also one of the simplest ways to secure your windows against break-ins.
Finding the right part
Window hardware varies by brand and age. We match parts for Andersen, Pella, Marvin, Truth and many other manufacturers. When an exact match is no longer made, we find a compatible replacement. Read more about common window lock problems.
Window hardware questions
Why does my window crank spin without opening the window?
The gears inside the operator are stripped. Replacing the operator fixes it, and it is a quick repair.
Can you match hardware on older windows?
In most cases, yes. We source original or compatible parts for most major window brands, including older models.
My window lock will not line up. Is the lock broken?
Not always. The sash may have dropped or shifted. We check the balance, the sash and the keeper and fix the real cause.
Can you add locks to make windows more secure?
Yes. We can add or upgrade sash locks and install window stops that limit how far a window opens.
