Door Knob Installation Problems Prevention

Why DIY Door Hardware Fails

Most door knob problems we fix started as weekend DIY projects. Homeowners drill holes slightly off-center, overtighten screws thinking tighter is better, or install the wrong backset measurement because they didn’t know it mattered.

The result? Doors that won’t close properly, handles that bind up, or latches that don’t catch. Then you’re stuck with a door that works poorly every single day.

Professional installation means precise measurements, proper alignment, and understanding how door thickness affects everything. We bring the right tools and decades of experience so your doors work perfectly from day one.

Lever Handles That Make Sense

Lever handles aren’t just a style choice – they’re practical. When you’re carrying groceries, dealing with arthritis, or just want doors that work effortlessly, levers beat traditional knobs every time. Just push down with your elbow and you’re through.

McCausland Lock Service installs lever handles that meet ADA accessibility guidelines and work smoothly for years. The secret is proper spring tension and precise strike plate alignment – details that separate professional installation from guesswork.

Modern lever designs also add sophisticated style to any home, available in finishes that complement your existing hardware perfectly.

Door Knobs & Levers FAQs

Common questions about our Door Knobs & Levers services

Professional door knob installation typically costs between $150-$350 per door, depending on the hardware complexity and any modifications needed. This includes labor and basic hardware, though premium lever handles or smart locks cost more. While DIY seems cheaper initially, improper installation often leads to security issues, premature wear, and needing professional correction later. We provide upfront pricing with no hidden fees, and our installations are done right the first time, saving you money and frustration down the road.
Door knobs require a twisting motion and firm grip to operate, while lever handles work with a simple push-down motion. Levers are significantly easier to use, especially for elderly residents, people with arthritis, or when your hands are full carrying things. They’re also ADA-compliant for accessibility requirements. However, knobs can be more secure against accidental opening by pets or small children. For most homeowners, levers offer better functionality and convenience, while knobs work well when you want to prevent easy access. We help you choose the right option based on your household needs.
In most cases, yes. Standard door preparations accommodate most quality door knobs and lever handles without major modifications. However, switching between different hardware types (like going from a knob to a lever) sometimes requires slight adjustments to hole sizes or strike plate positioning. We assess your existing doors during our evaluation and explain any modifications needed upfront. Our goal is working with your existing doors whenever possible, saving you the cost and hassle of door replacement while ensuring proper fit and function.
A properly installed door knob or lever should operate smoothly without binding, the door should close completely without popping open, and the latch should engage securely with the strike plate. You shouldn’t need excessive force to operate handles, and there should be no visible gaps or misalignment. Common signs of poor installation include loose handles, doors that won’t stay closed, difficulty operating the mechanism, or visible wear after just a short time. Professional installation includes testing all these elements and making adjustments to ensure everything works perfectly before we leave.
We work with premium manufacturers including Kwikset, Medeco, and Schlage – brands known for reliability, security, and longevity. These companies offer excellent warranties and proven track records in residential and commercial applications. The specific brand we recommend depends on your security needs, budget, and style preferences. Kwikset offers great value for standard residential use, while Medeco provides high-security options for enhanced protection. Schlage strikes a good balance between security and style. We’ll discuss your specific needs and help you choose hardware that fits your requirements and budget.
Yes, we provide emergency locksmith services when door hardware failures leave you locked out or unable to secure your home.
