Why Professional Lock Installation Matters
Proper lock installation involves more than attaching hardware to a door. Incorrect installation can cause alignment problems, difficult operation, and premature wear. During installation, we check:
- Door thickness and lock compatibility
- Existing bore holes and door preparation
- Deadbolt and latch alignment
- Strike plate positioning
- Screw length and mounting stability
- Smooth lock and key operation
- Electronic lock functionality, where applicable
Our goal is to make sure the installed hardware operates properly and is suitable for the door. Our installation labor is backed by a 90-day workmanship warranty.
