A wobbly door knob isn’t just annoying. It’s a sign something wasn’t done right—wrong alignment, cheap parts, or someone who didn’t know what they were doing.
When your door hardware is installed correctly, the latch catches smoothly every time. The knob turns without sticking. The lock actually keeps your door secure instead of just looking like it does.
You’re not calling someone back in six months because the knob fell off or the mechanism jammed. The door closes properly without you having to lift it or push it in a specific way. Your keys turn without fighting the cylinder.
That’s what happens when a locksmith who knows what they’re doing installs hardware that’s actually built to last. No plastic internals that crack. No misaligned strike plates. No shortcuts that come back to bite you later.
We’ve been handling locksmith work since the late 1800s. Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront, and we’ve been serving Edgmont homeowners for decades.
When Delaware County families keep coming back generation after generation, it’s because the work holds up. We’re not the cheapest option in Edgmont—and that’s actually a good thing for you. You’re getting manufacturer-approved parts from Kwikset, Medeco, and Schlage, not whatever’s on sale at the big box store.
We explain what’s wrong, what it takes to fix it, and exactly what it costs before we touch anything. No surprises, no upselling, no damage to your door or frame that you’ll have to repair later.
You call or message us about the door knob work you need. We ask a few questions about your door type, what hardware you’re replacing, and whether you’ve already purchased new knobs or need recommendations.
We schedule a time that works for you and show up when we say we will. If you haven’t bought hardware yet, we’ll bring options from the manufacturers we trust—the ones with metal internals and actual warranties.
Before we start, we walk you through what we’re doing and confirm the cost. Then we remove the old hardware without damaging your door, check the bore hole and strike plate alignment, and install the new knob or lever set properly. That means the latch is positioned correctly, the strike plate is aligned so your door actually latches, and the screws are tightened to manufacturer specs.
We test everything before we leave. The door closes smoothly. The latch catches. The lock engages. Your keys work without forcing them. The whole job typically takes 20 to 30 minutes per door, and we clean up after ourselves.

We handle the complete installation during one visit. That includes removing your old hardware without splintering the wood or scratching your door, installing the new knob or lever set with proper alignment, and making sure the strike plate is positioned so your door actually latches when you close it.
If your door has issues beyond just the hardware—like a bore hole that’s the wrong size or a door that’s sagging—we’ll tell you upfront. We’re not going to install a new knob on a door that won’t close properly and pretend that solves your problem.
In Edgmont and throughout Delaware County, we’re seeing more homeowners upgrade to higher-security hardware. That makes sense given the recent uptick in break-ins in nearby Concord and Chadds Ford Townships. A solid deadbolt paired with a quality knob set is your first line of defense, and we can handle both installations at once.
We stock the parts we need on our trucks, so you’re not waiting for an order to come in. And because we’re using manufacturer-approved components from Kwikset, Medeco, and Schlage, you’re getting hardware that’s built to handle daily use without falling apart.
For a basic door knob installation, you’re looking at around $150 to $357 depending on the hardware you choose and whether there are any complications with your door. Interior door knobs typically run $232 to $480 when you factor in both the hardware and professional installation.
Here’s what affects the price: the quality of the knob or lever set you’re installing, whether we’re working with a standard bore hole or need to drill a new one, and if there are alignment issues with your door that need to be corrected first. A simple swap on a door that’s in good shape costs less than installing new hardware on a door that’s sagging or has a damaged frame.
We give you the exact cost before we start any work. No surprises, no “oh, by the way” charges after we’re halfway done. If your door has problems that will affect the installation, we tell you upfront what it’ll take to do the job right.
The door knobs you’ll find at most big box stores have plastic parts inside the mechanism. They’re lighter, they feel less solid when you turn them, and they’re built to hit a price point, not to last.
The hardware we install from Kwikset, Medeco, and Schlage uses metal internals. When you turn the knob, you can feel the difference—it’s firm and smooth, not loose or plasticky. These aren’t just going to hold up better over time; they’re also harder to force or break if someone tries to get through your door.
We stock manufacturer-approved parts because we’ve seen what happens with the cheap alternatives. You save $30 upfront, then you’re calling someone back in a year because the knob is wobbly or the lock mechanism failed. Quality components cost more initially, but you’re not replacing them every couple of years.
Yes, and that’s actually one of the main reasons to hire someone who knows what they’re doing. We remove old hardware and install new knobs without splintering wood, scratching your door, or breaking anything in the process.
The problems usually happen when someone doesn’t understand how the door knob components fit together or tries to force something that’s not aligned correctly. We’ve seen doors with gouges around the knob from someone prying at it, stripped screw holes from overtightening, and even cracked door edges from improper installation.
We use the right tools and we know how door hardware is supposed to come apart and go back together. If there’s an issue with your door—like an oversized bore hole or a damaged edge—we’ll tell you about it and explain your options. But the installation itself won’t create new damage.
A straightforward door knob replacement typically takes 20 to 30 minutes per door. That’s removing the old hardware, installing the new knob or lever set, aligning everything properly, and testing it to make sure it works smoothly.
If we’re installing hardware on a new door or dealing with alignment issues, it might take longer. Same thing if you’re upgrading from a basic knob to a higher-security lock set or adding a deadbolt at the same time.
We don’t rush the job just to get to the next call. Your door knob needs to be installed correctly—the latch has to align with the strike plate, the screws need to be tightened to the right tension, and everything needs to function smoothly before we leave. Taking an extra ten minutes to get it right means you’re not calling us back because something’s not working.
A loose door knob usually means the screws have worked themselves out over time, or the internal mechanism is worn out. Sometimes it’s a quick fix—tightening the set screws or the screws that hold the knob to the door. Other times, the hardware itself is shot and needs to be replaced.
If you’ve already tried tightening everything and the knob is still wobbly, the spindle or the internal components are probably worn. That’s common with cheaper hardware or knobs that have been in use for years. At that point, you’re better off replacing the whole set rather than trying to patch it together.
We can assess what’s going on and tell you whether it’s worth repairing or if you need new hardware. If the door knob is loose because your door is sagging or the frame has shifted, we’ll catch that too—because installing a new knob won’t fix a structural issue with the door itself.
Yes, we install smart locks and electronic door hardware. More Edgmont homeowners are upgrading to keyless entry systems, and we handle the installation and programming for brands like Kwikset and Schlage.
Electronic locks need to be installed correctly or they won’t function reliably. The door has to close and latch properly, the strike plate needs to be aligned precisely, and the lock mechanism has to be mounted securely. If any of that’s off, you’ll have issues with the lock not engaging or the batteries draining faster than they should.
We also make sure you understand how to program and use your new smart lock before we leave. That includes setting up access codes, connecting it to your phone if it’s a Wi-Fi or Bluetooth model, and showing you how to troubleshoot basic issues. You’re not figuring it out on your own after we’re gone.
