You turn the knob and the door opens. You lock it and it stays locked. The handle doesn’t wobble when you grab it, and the latch catches every single time you close the door.
That’s what you’re paying for. Not just the hardware itself, but the installation work that makes everything function the way it should. A door knob that’s installed correctly doesn’t come loose six months later. It doesn’t stick or require you to lift the door while you turn the handle.
Most problems with door hardware come down to installation. The strike plate isn’t aligned right, the screws are too short, or someone used the wrong parts for your door thickness. When we install or replace door knobs and levers in Colwyn homes, we’re looking at the whole picture—how your door sits in the frame, whether the hinges need adjustment, and what type of hardware actually works with your setup.
You get hardware that works smoothly from day one and keeps working. No callbacks, no adjustments, no “living with it” because it’s close enough.
Our family has been doing locksmith work since the late 1800s. We’re now on our fourth generation, with Tom McCausland and his daughter Chrissy running the largest locksmith operation in the Delaware Valley.
Our shop is right down the road in Prospect Park at 1101 Lincoln Ave. We’ve worked on thousands of homes throughout Colwyn and Delaware County—everything from pre-1940s rowhomes to newer construction. We know the quirks that come with older doors, the hardware that holds up, and what actually works in real-world conditions.
When you call us, you’re getting technicians who show up in fully stocked mobile workshops. We carry Kwikset, Schlage, and Medeco products, plus the specialized tools needed to install them correctly. No running to the hardware store mid-job or coming back another day because we didn’t bring the right parts.
You call or contact us with your door hardware issue. We ask a few questions about what’s going on—whether the knob is loose, the lock isn’t catching, or you’re replacing old hardware entirely.
We schedule a time that works for you. Our technicians typically arrive within 20-30 minutes for emergency situations, or at your scheduled appointment for planned replacements. When we get there, we assess your door and frame to see what’s needed. Sometimes it’s a straightforward swap. Other times we need to adjust the strike plate, reposition the latch, or address issues with how the door sits in the frame.
Before we touch anything, we explain what’s wrong, what it takes to fix it, and exactly what it costs. No surprises, no hidden fees. Once you approve, we do the work. We install the new door knob or lever, test it multiple times to make sure it latches properly, and verify the lock engages smoothly. If we notice your door needs adjustment or your hinges are sagging, we’ll mention it. We can often handle that work during the same visit if you want it done.
You’re left with door hardware that works the way it should. We clean up, answer any questions you have, and you’re done.

We handle the full installation—removing old hardware, prepping the door if needed, installing the new knob or lever, and making sure everything aligns correctly. That includes the strike plate, latch assembly, and any interior/exterior components.
You’re getting OEM-quality parts, not the plastic-filled hardware from big box stores. The door knobs and levers we install have solid internal components that hold up to daily use. We work with brands like Kwikset, Schlage, and Medeco because they make hardware that lasts.
Colwyn has a lot of older homes—38.4% of housing stock was built before 1940. Older doors often need extra attention during installation. The door thickness might be different, the frame might have settled over time, or previous hardware installations left oversized holes. We account for all of that. If your door needs reinforcement plates or longer screws to hold the hardware securely, we have them in our trucks.
We also handle lever installation and lever repair for residents who prefer lever-style hardware over traditional knobs. Levers are easier to operate and work well for accessibility needs. The installation process is similar, but levers put different stress on the door, so proper mounting is critical.
If you’re a landlord managing rental properties in Colwyn—where 44.2% of housing units are renter-occupied—we can handle multiple units and coordinate with your schedule. We’ve worked with property managers throughout Delaware County who need reliable door hardware installation without the back-and-forth.
Door knob installation typically runs between $80 and $357 depending on the complexity of the job and the hardware you’re installing. A basic knob replacement on a standard interior door sits at the lower end. Exterior door hardware with deadbolts, higher-security locks, or installations that require door prep work cost more.
We give you a written estimate before starting any work. You’ll know exactly what you’re paying for—the hardware itself, the labor, and any additional work like strike plate adjustment or door reinforcement. There are no hidden fees or surprise charges after the job is done.
The price difference usually comes down to the quality of parts and whether your door needs extra work. Cheap hardware might save you $30 upfront, but it’ll likely need replacement sooner. Professional-grade door knobs have metal internal components instead of plastic, which means they hold up better over time.
Yes. We work on older homes throughout Colwyn regularly, including houses built before 1940. Older doors come with their own set of challenges—non-standard thicknesses, settled frames, and previous hardware installations that left oversized holes or damaged wood.
We carry reinforcement plates, longer screws, and wood filler for situations where the existing holes are too large or stripped out. If your door has shifted in the frame over the years, we can adjust the strike plate position so the latch catches properly. Sometimes older doors need the hinges tightened or repositioned before new hardware will work correctly.
Our family has been doing this work since the late 1800s, so we’ve seen just about every door configuration you can imagine. We know how to adapt modern hardware to older door setups without compromising security or function. Your door might be 80 years old, but the hardware we install will work just as smoothly as it would on new construction.
Door knobs require you to grip and twist. Door levers require you to push down. That’s the functional difference, and it matters depending on who’s using the door and what your accessibility needs are.
Levers are easier to operate if you have your hands full, if you have arthritis or limited hand strength, or if you’re trying to meet ADA accessibility requirements. You can push a lever down with your elbow or forearm. You can’t do that with a knob.
The installation is similar, but levers put different mechanical stress on the door because of the downward force. They need to be mounted securely or they’ll sag over time. We make sure the mounting screws go into solid wood and use reinforcement plates when necessary. Both styles come in keyed and non-keyed versions, and both can be installed on interior or exterior doors. It’s mostly a matter of preference and practicality for your situation.
A straightforward door knob replacement on a standard door usually takes 20 to 45 minutes. That includes removing the old hardware, installing the new knob or lever, adjusting the strike plate if needed, and testing everything to make sure it works smoothly.
More complex jobs take longer. If your door needs adjustment, if we’re installing high-security locks, or if we’re repairing damage from previous installations, it might take an hour or more. We’ll give you a time estimate when we assess the job.
We don’t rush through installations just to get to the next call. Door hardware that’s installed correctly the first time saves you from callbacks and future problems. We test the latch multiple times, verify the lock engages properly, and make sure the door closes without resistance. You’re not paying us to slap hardware on and leave—you’re paying for installation work that holds up.
We carry a range of door knobs and levers in our mobile workshops. Our trucks are stocked with Kwikset, Schlage, and Medeco products in various styles and finishes. For most standard installations, we have what you need on hand.
If you’ve already purchased specific hardware and want us to install it, we can do that too. Just know that if there’s an issue with the parts you bought—wrong size, missing components, or low-quality construction—we’ll let you know before we start the installation. We’ve seen plenty of big box store hardware that looks fine in the package but has plastic internal parts that fail quickly.
If you want to see options in person before deciding, you can stop by our storefront in Prospect Park at 1101 Lincoln Ave. We’re open Monday through Friday, 8:30 AM to 5:00 PM. You can look at different styles, feel the quality difference between product lines, and talk through what makes sense for your doors. Then we can schedule the installation and bring exactly what you need.
If your door won’t latch properly, it’s usually an alignment issue between the latch and the strike plate—not a problem with the door knob itself. This happens when the door has settled, the hinges are loose, or the strike plate is positioned incorrectly.
We check alignment before we finish any installation. We test the door multiple times to make sure the latch catches smoothly without you having to lift or push the door into position. If there’s an alignment problem, we adjust the strike plate or tighten the hinges to fix it during the same visit.
That’s the difference between professional installation and DIY work. A homeowner might install the door knob correctly but miss the fact that the door is sitting a quarter-inch too low in the frame. We’re looking at the whole system—the door, the frame, the hinges, and the hardware—to make sure everything works together. You shouldn’t have to fight with your door every time you close it, and you won’t if the installation is done right.
