Inspection checklist
- Check the operating pattern
- Separate fit from hardware damage
- Confirm the final fit
A window lock may be difficult to close because the hardware is damaged or because the sash is not reaching its intended position. Those causes need different repairs.
Use these points to understand the opening or system before choosing parts or approving a larger replacement.
Call or send photos with your ZIP code. We review the visible condition, confirm the service area and schedule an on-site estimate when measurements or equipment identification are required. On site, we verify dimensions, identify compatible parts and explain the work before the customer approves a repair or installation.
Describe whether the sash stops short, tilts, drags or reaches the closed position but still will not lock. A lock installed recently may also have an incompatible mounting position or keeper. Avoid forcing it against resistance.
The inspection should consider sash alignment, tracks, balances and the frame as well as the lock. Replacing a latch does not resolve a sash that cannot close properly. Photos of both mating parts help identify what is installed.
After repair, review closing and locking without unusual force. Ask whether the existing keeper can be reused and whether any damaged sash or frame material needs repair. Replacement parts should fit the actual window, not simply match its finish.
A new lock alone does not correct the sash alignment. The cause of the crooked position should be assessed.
Manufacturer labels, mounting details and clear photos of the lock and keeper help narrow the options.
No. Resistance can also come from a sash or keeper that is out of position.
