You stop jiggling the handle three times before it opens. You stop worrying whether the front door actually locked when you left for work. Your key turns smoothly instead of catching halfway.
That’s what happens when door knob installation gets done with the right parts and proper alignment. The latch catches on the first try. The lock engages without forcing it. The handle sits flush against the door instead of pulling away when you grab it.
We’re not patching problems with hardware store parts that’ll loosen up in six months. You get OEM components that match your door’s specifications, installed by technicians who’ve been doing this work in Delaware County since the late 1800s. The job gets completed in one visit, and you’re not calling us back because something didn’t hold.
We’ve been handling door hardware in Folsom since before your grandparents bought their first home here. We’re the largest locksmith operation in the Delaware Valley, run by fourth-generation locksmith Tom McCausland and his daughter Chrissy from our Prospect Park storefront.
When you call, you’re getting our technicians—not subcontractors, not a call center routing you to whoever’s available. We know Folsom’s mix of historic homes and newer construction because we’ve worked on both for over 140 years.
That’s why your neighbors keep our number. We show up when we say we will, we explain what’s wrong before touching anything, and we give you a written estimate before starting work.
You call or contact us about your door knob problem. We ask a few questions about what’s happening—is it loose, jammed, not locking—so we know what parts to bring.
Our technician arrives in a fully equipped mobile workshop. Before doing anything, they assess the door, check the alignment, and explain what needs to happen. You get a written estimate right there. No surprises, no upselling to things you don’t need.
Once you approve, we handle the installation or repair on the spot. That includes removing the old hardware, checking the door bore and latch alignment, installing the new components with proper torque specs, and testing everything multiple times. If it’s a smart lock or electronic deadbolt, we program it and make sure it integrates correctly with your door.
You test it yourself before we leave. The handle should feel solid, the lock should engage smoothly, and the latch should catch without adjustment. If something’s not right, we fix it then—not after you’ve already paid and we’ve driven away.

We install new door knobs, repair existing hardware, replace broken locks, and upgrade to smart lock systems. The service covers interior and exterior doors, including entry doors, bedroom doors, bathroom privacy locks, and passage hardware.
Folsom’s older homes often need special attention. Historic properties have door thicknesses and bore sizes that don’t match modern hardware specs. We carry adapters and custom solutions for doors that were hung before standardized measurements existed. Your 1920s oak door doesn’t need to be modified to accept current hardware—we make the hardware work with your door.
For newer construction in Folsom, we install the brands you actually want: Kwikset, Schlage, Medeco. We also handle electronic locks and smart deadbolts that require proper setup, not just physical installation. That means programming user codes, syncing with your phone, and making sure the electronic components don’t drain batteries in two weeks because the door wasn’t prepped correctly.
Every job includes testing the strike plate alignment, checking the door swing, and verifying the latch engages properly. You’re not getting hardware slapped on and a handshake goodbye.
Door knob installation typically runs between $150 and $250 per door, depending on the hardware you choose and whether we’re working with a standard door or something that needs modification. That price includes the service call, labor, and basic installation.
If you’re supplying your own hardware from a big box store, we can install it—but we don’t warranty parts we didn’t provide. When we supply the door knob, you’re getting OEM components with a warranty, and we stand behind both the parts and the installation.
The price goes up if your door needs repairs before we can install new hardware. A stripped screw hole, a cracked bore, or a misaligned frame adds time and materials. We’ll tell you about those issues during the initial assessment, before we start any work, so you can decide whether to proceed.
Yes, and we make sure it actually works the way it’s supposed to. Smart locks and electronic deadbolts fail when the door prep is wrong or the installation skips steps that matter for electronic components.
We check your door thickness, bore size, and backset measurement before recommending a specific model. Not every smart lock fits every door, and forcing the wrong one leads to battery drain, connectivity problems, and mechanisms that jam after a few weeks.
Once we install it, we program your user codes, sync it with your phone if it’s app-controlled, and test the auto-lock function multiple times. You’ll know how to add and delete codes, what to do if the battery dies, and how to use the backup key access. We don’t just mount the hardware and hand you the box with the instructions still inside.
Loose door knobs usually mean the set screw has backed out or the interior mechanism is wearing down. Tightening the screw might fix it temporarily, but if the knob keeps loosening, something else is going on.
The spindle could be worn, the rose plate might be cracked, or the bore hole could be wallowed out from years of the hardware shifting. We’ll diagnose the actual cause when we look at it. Sometimes it’s a ten-minute tightening job. Other times, the hardware needs replacement because the internal components are shot.
If it’s just loose hardware on a newer door, we’ll tighten it and apply thread-lock so it stays put. If the door knob is old and the mechanism is failing, we’ll explain what’s happening and give you options—repair it if possible, or replace it with hardware that’ll last another decade. You decide based on what makes sense for your situation and budget.
If you’re replacing door knobs because you just bought the house, yes—rekey everything. You don’t know who has keys from the previous owner, their family, contractors, or neighbors who kept a spare.
When we install new door hardware, we can rekey all your exterior locks to work on the same key. That means one key for your front door, back door, side entrance, and deadbolts. You’re not fumbling through a key ring every time you come home.
Rekeying costs less than replacing all the lock cylinders, and it gives you the same security benefit. We swap out the pins inside the cylinder so old keys no longer work, and you get new keys cut on the spot. If you’re keeping some of your existing door knobs and just replacing a few, we can rekey the old ones to match the new hardware. Everything works on one key, and you control who has access.
A straightforward door knob installation on a standard door takes about 30 to 45 minutes per door. That includes removing the old hardware, installing the new components, and testing everything before we leave.
If we’re installing multiple door knobs throughout your house, the time adds up—but we’re not charging you a separate service call for each door. We handle them all in one visit.
The timeline extends if your door needs prep work. Drilling a new bore, repairing a damaged strike plate, or adjusting a misaligned frame adds time. Smart locks take longer than mechanical hardware because of the programming and setup steps. We’ll give you a time estimate when we assess the job, so you know whether to block off an hour or an afternoon.
We install Kwikset, Schlage, Medeco, and other major lock manufacturers that make hardware worth putting on your door. These aren’t the cheapest options at the big box store—they’re the ones that hold up under daily use and don’t need replacement in two years.
Kwikset offers solid residential options with SmartKey technology that lets you rekey the lock yourself. Schlage makes commercial-grade deadbolts that work well on exterior doors in high-traffic homes. Medeco is the choice when you need high-security locks that resist picking, bumping, and drilling.
We carry these brands because we’ve installed thousands of them across Delaware County, and we know how they perform long-term. If you’ve already bought hardware and need it installed, we can do that—but when we supply the parts, you’re getting OEM quality with a warranty. You won’t be calling us back next month because the finish is peeling or the mechanism is sticking.
