Understanding the Price of a Lock Change
Many factors influence the cost of a lock replacement, from the type of lock (deadbolt, knob, lever) to the security grade you select. We also consider the condition of your existing door and frame, as proper installation requires a sound foundation. Our service call fee of $49 covers the initial assessment.
After our technician evaluates your specific needs in Riverdale, you will receive a detailed quote. This quote outlines the cost of the new hardware and labor, agreed upon by you before we dispatch a van to begin the work. This upfront approach ensures there are no surprises regarding the final price for your lock replacement.
Why a Proper Door Assessment Matters
A new lock is only as secure as the door and frame it's installed into. Before installing any new deadbolt or knob, we thoroughly inspect the door's alignment, the condition of the strike plate, and the integrity of the door jamb. Often, what appears to be a failed lock is actually a misaligned door or a worn strike.
We ensure that the foundation is strong, addressing issues like loose hinges or weak jambs, which might require longer screws into the stud. Installing a Grade 1 deadbolt into a hollow jamb with short screws offers minimal security. Our goal is to provide a complete and lasting security upgrade for your Riverdale home.
Selecting the Right Hardware for Your Home
When it's time to replace your door locks, you have options beyond just aesthetics. We offer a range of hardware, from standard Grade 2 residential locks to more robust Grade 1 commercial-rated deadbolts, all matched to your desired finish. You can choose to have your new locks keyed alike to an existing key, simplifying your everyday access.
We handle full replacement of deadbolts, knobs, levers, and even mortise bodies. Whether your existing hardware is worn out, damaged, outdated, or simply not meeting your security needs after a concern in your Riverdale neighborhood, we help you select and install the appropriate and secure solution.
