A properly installed door knob or lever doesn’t wiggle. It doesn’t stick halfway through the turn. The latch catches cleanly every single time you close the door.
You’re not dealing with stripped screws three months later or a handle that feels like it’s about to fall off. The strike plate lines up. The mechanism operates smoothly. Your door closes securely without you having to lift, push, or jiggle anything.
That’s what happens when someone who understands door hardware does the installation. You get hardware that matches your home’s style, functions the way it’s supposed to, and doesn’t become another thing on your fix-it list six months down the road.
We’ve been handling locksmith work since the late 1800s. That’s 140+ years of the McCausland family doing this exact type of work across Delaware County.
Tom McCausland runs the largest locksmith operation in the Delaware Valley, and his daughter Chrissy represents the fourth generation in the business. When you’re in Thornbury and need door hardware installed correctly, you’re calling people who’ve been serving this area longer than most companies have existed.
We’re not a handyman service that does locks on the side. This is what we do, and we stock the parts and hardware that actually last in homes like yours.
You call or contact us with what you need. We discuss the hardware you want installed, whether you already have it or need recommendations based on your door type and security needs.
We schedule a time that works for you. Our locksmith arrives with the tools and knowledge to handle whatever your door requires—whether it’s a standard installation, a tricky alignment issue, or hardware that needs to match existing finishes throughout your home.
The installation happens efficiently. We mount the hardware correctly, ensure the latch mechanism aligns with the strike plate, test the operation, and make any adjustments so everything functions smoothly. You’re left with door hardware that works properly and will continue working properly because it was installed by someone who knows what they’re doing.
If you need multiple doors done or want to rekey locks while we’re there, we handle it in the same visit. No need to schedule multiple appointments or coordinate different contractors.
Ready to get started?
You get proper hardware installation using manufacturer-approved methods. We work with Kwikset, Schlage, Medeco, and other quality brands, so whether you’ve purchased hardware yourself or need us to supply it, we’re installing products we know will hold up.
Thornbury homes—with a median value over $730,000—deserve hardware that matches their quality. You’re not getting cheap parts that fail or installation shortcuts that cause problems later. We use OEM parts and proper techniques because that’s what prevents callbacks and ensures your door hardware actually lasts.
The installation includes alignment checks, strike plate adjustment, and operational testing. If there are existing issues with your door frame or alignment that would affect performance, we identify those and discuss solutions before they become bigger problems.
We also handle rekeying during the same visit if you want all your locks on one key system, which most Thornbury homeowners prefer for convenience and security.
Professional door knob installation generally runs between $150 and $357 per door, depending on the hardware you choose and any complications with the existing door or frame. That includes labor and proper installation.
If you already own the hardware, you’re paying for the installation service and expertise. If we’re supplying the hardware, the cost reflects both the quality of the product and the installation work.
The real cost consideration isn’t just the upfront price—it’s whether the job gets done right. Poor installation leads to loose hardware, security vulnerabilities, and hardware failure that costs you more in the long run. You’re paying for someone who knows how to handle alignment issues, install strike plates correctly, and ensure everything functions properly from day one.
Yes, we can install hardware you’ve already purchased. Bring us whatever you bought, and we’ll handle the installation.
That said, not all hardware is created equal. If you purchased something that won’t work well with your door type or doesn’t meet your security needs, we’ll tell you before we install it. We’d rather have that conversation upfront than install something you’ll be unhappy with.
We stock quality brands like Kwikset, Schlage, and Medeco because we know they perform well and last. If you’re still in the shopping phase, we can recommend hardware that fits your door, matches your home’s style, and meets your functional needs. Either way, the installation will be done correctly.
A straightforward door knob or lever installation typically takes 30 to 45 minutes per door. That’s for a standard installation where the door is in good condition and the hardware is compatible.
If there are complications—misaligned doors, damaged frames, or old hardware that didn’t come out cleanly—it can take longer. We handle those issues as they come up, but we’re not padding time. We’re fixing what needs fixing so your hardware works right.
If you’re having multiple doors done or adding rekeying service, we work efficiently through everything in one visit. Most homeowners appreciate getting several doors handled at once rather than scheduling separate appointments. We’re typically in and out faster than you’d expect, and everything works properly when we leave.
The main difference is whether it gets done correctly the first time. Door knob installation looks simple until you’re dealing with misaligned holes, stripped screws, or a latch that won’t catch properly.
We install door hardware correctly because we’ve done it thousands of times. We know how to handle alignment issues, when a strike plate needs adjustment, and how to ensure the mechanism operates smoothly. We also catch problems with the door or frame that would cause issues down the road.
DIY installation often leads to loose hardware, security gaps, or functional problems that require a professional fix anyway. You end up paying twice—once for the hardware and your time, and again to have it done right. If your time is valuable and you want hardware that actually works properly, professional installation makes sense from the start.
We typically arrive within 20 to 30 minutes for emergency locksmith services throughout Delaware County, and we can often accommodate same-day installation requests for door hardware.
It depends on our schedule and what you need done. If you call in the morning with a straightforward installation request, there’s a good chance we can get to you the same day. If you need multiple doors done or have specific hardware requirements, we might schedule it for the next available opening.
Either way, we’re not making you wait weeks for service. We run the largest locksmith operation in the Delaware Valley with a fully stocked mobile fleet, which means we have the capacity to handle jobs quickly. Call us and we’ll let you know exactly when we can get there.
Yes, we rekey locks as part of our standard locksmith services, and we can absolutely rekey your new door knobs to match your existing key system.
Most Thornbury homeowners want all their locks on one key for convenience. When we install new door hardware, we can rekey everything during the same visit so you’re not carrying multiple keys or worrying about which key goes to which door.
We handle this type of work constantly. Whether you’re replacing one door knob or upgrading hardware throughout your home, we’ll set up your key system however makes the most sense for you. It’s a straightforward process when you’re working with an actual locksmith rather than a general contractor who has to call someone else for the lock work.
