Why Your Kensington Home Might Need New Locks
Kensington features a diverse housing stock, from historic homes that often incorporate original mortise locks to modern builds with standard cylindrical sets. Over time, environmental factors, everyday wear, and evolving security needs can degrade even robust hardware. A key that no longer turns smoothly, a deadbolt that feels flimsy, or a lock that is visibly corroded signals it may be compromised.
We specialize in assessing the specific requirements of your property, whether it features a classic wooden doorframe or a contemporary composite door. Our technicians ensure that any new installation, from Grade 1 deadbolts to knob or lever sets, is correctly matched and integrated with your home's existing structure and aesthetic. We prioritize function and security with every lock change.
Precision Lock Replacement for Lasting Security
Replacing a lock involves more than just swapping out hardware. Our process begins with a thorough inspection of the door's alignment, the strike plate, and the condition of the door jamb. Often, what appears to be a failed lock is actually a misaligned door or a worn strike plate, which compromises even the highest-grade deadbolt. Addressing these underlying issues ensures the new lock functions correctly and provides maximum security.
We carry a range of residential hardware options, allowing you to choose finishes and styles that complement your Kensington home. During installation, we ensure correct backset and bore hole dimensions. If requested, we can re-key your new locks to operate with your existing house key, streamlining your key management while upgrading your security.
What's Included with Your Lock Change Service?
Our lock change service includes the precise installation of new deadbolts, door knobs, and lever handles. We can replace entire mortise lock bodies commonly found in older Kensington properties. If you are upgrading, we offer Grade 1 and Grade 2 commercial-rated hardware suitable for enhanced residential security. This service extends to strike plate and door jamb reinforcement to withstand forced entry attempts.
You receive comprehensive service from our Greenbelt, MD dispatch base, ensuring all new components are correctly fitted and operate smoothly. We can also key your new locks alike to your current house key, a convenient option for managing access. Our aim is to provide a complete and secure solution that lasts.
