The Hidden Costs of an Improper Lock Change
Installing a new lock without checking the door's alignment or reinforcing the strike plate is a common oversight that undermines security. A heavy-duty Grade 1 deadbolt mounted into a soft, hollow door jamb with short screws remains vulnerable to forced entry, negating the investment in quality hardware. This often leads to needing another replacement sooner than expected.
Overlooking a slight door sag or a worn hinge when replacing a lock can cause a new cylinder to bind or strain, leading to its early failure. This means repeated service calls or the need to purchase another lock, adding unnecessary expense. Our technicians look at the complete door assembly, not just the lock. We ensure all components work together for lasting security.
Our Process: Matching Security to Your Door's Needs
Our lock change process begins with a thorough inspection of your existing door and frame. We check for common issues like door misalignment, worn strike plates, or jambs that require reinforcement. Understanding these factors allows us to recommend hardware that genuinely enhances your security rather than just replacing a failing part. We measure the backset and bore hole to ensure a perfect fit for any new knob, lever, or deadbolt.
We provide a range of residential lock options, including Grade 1 and Grade 2 commercial-rated hardware for superior durability and protection. Whether you need a simple knob replacement or a high-security deadbolt, we ensure the hardware finish matches your home's aesthetic. On request, we can key new locks to your existing house key, simplifying your daily routine.
Comprehensive Lock Solutions for Every Residential Need
Our services cover the full spectrum of residential lock change requirements. This includes the replacement of standard knob sets, lever handles, and deadbolts. We also handle more complex tasks such as replacing mortise lock bodies, which are often found in older homes and require precise fitting.
Reinforcing your door's security extends beyond the lock itself. We can upgrade your strike plates and jamb hardware, utilizing longer screws that anchor into the door frame's studs. This significantly increases resistance against kick-ins. Every installation ensures your new hardware is correctly fitted and performs as intended, providing reliable protection for your Severn home.
