You shouldn’t have to jiggle your door handle for three minutes just to get inside your own house. You shouldn’t stand outside in January while your deadbolt refuses to turn.
When door hardware fails, it’s not just annoying. It’s a security risk, an embarrassment when guests arrive, and a daily frustration that eats away at you every single time you come home.
Professional door knob installation fixes this permanently. The right hardware, installed correctly, means your doors work smoothly every time you touch them. No sticking, no loose handles, no wondering if the lock actually engaged when you left for work.
You get hardware that matches your home’s style, functions reliably in every season, and gives you confidence that your family and belongings are actually secure. Most installations take under an hour, and you’re done dealing with that problem for years.
We’ve been handling residential locksmith work in the Delaware Valley since the late 1800s. Chuck and Tom McCausland represent the fourth generation of locksmiths in our family, running the largest locksmith operation in the region from our Prospect Park storefront.
Brookhaven homeowners keep coming back because we show up when we say we will, we use OEM parts that actually last, and we don’t create new problems while fixing old ones. Most of the homes in your neighborhood were built in 1969, which means door frames, hardware, and locks have seen decades of use and weather.
We understand what fails first in older homes and what modern hardware works best with your existing doors. You’re not getting a call center or a subcontractor. You’re getting experienced locksmiths who’ve been serving your neighbors for longer than most companies have existed.
You call or stop by our Prospect Park location at 1101 Lincoln Ave. We discuss what’s failing, what you need, and whether repair or replacement makes more sense for your situation. No pressure, just honest assessment.
If you need new hardware, we help you select the right door knobs or levers for your specific doors and usage. Interior doors need different hardware than exterior doors. High-traffic areas need more durable mechanisms than guest bedrooms.
We schedule a time that works for you, usually same-day or next-day. Our mobile service arrives with the parts and tools needed to complete the job without multiple trips. We remove old hardware carefully to avoid damaging your door or frame, install new components properly aligned and secured, and test everything before we leave.
You get doors that latch correctly, locks that engage smoothly, and hardware that feels solid when you use it. The whole process typically takes 20-30 minutes per door, depending on complexity. We clean up completely and show you how everything works before we’re done.
Ready to get started?
You get proper assessment of your existing doors and frames before any work starts. Not every door can handle every type of hardware, and forcing the wrong fit creates bigger problems down the road.
We carry quality products from Kwikset, Schlage, and Medeco. These aren’t the cheapest options at the big box store, and that’s intentional. You’re investing in hardware that functions correctly in Pennsylvania winters and doesn’t need replacement in two years.
Installation includes proper boring if needed, correct alignment of strike plates, and adjustment of door fit if your door has settled over time. Many door knob problems aren’t actually hardware problems—they’re door alignment problems that cause hardware to fail prematurely.
For Brookhaven homeowners upgrading to smart locks or electronic deadbolts, we assess door compatibility first. Electronic locks require proper door thickness, good alignment, and sometimes additional reinforcement. We handle the full integration so your smart lock actually works reliably instead of draining batteries every month because it’s fighting a misaligned door.
You also get rekeying service if needed, so your new locks work with your existing keys or we can set up a master key system that reduces how many keys you’re carrying.
Installation typically runs $80-150 per door for labor, plus the cost of hardware. The total depends on what you’re installing and what condition your doors are in.
A basic interior door knob replacement on a door in good condition sits at the lower end. Exterior door hardware with deadbolts, smart locks, or situations where we need to repair door frame damage or fix alignment issues cost more.
We give you a clear price before starting work. No surprise charges, no “we found another problem” upsells. If your door needs additional work to function properly, we explain why and what it costs before proceeding.
The investment makes sense when you consider that properly installed hardware lasts 10-15 years or longer, while cheap hardware or poor installation means you’re paying again in two years.
Usually, yes—but it depends on your specific door’s thickness, condition, and how well it’s aligned in the frame.
Smart locks need doors that close smoothly and latch without force. If you’re currently shouldering your door shut or lifting the handle to get it to latch, that needs to be fixed first. Electronic locks fighting against misalignment drain batteries fast and fail prematurely.
Most Brookhaven homes were built in 1969, and many original doors are solid wood, which is actually ideal for smart lock installation. The challenge is usually frame settling over decades, which we can address during installation.
We assess your door before recommending specific smart lock models. Some work better with certain door thicknesses or backset measurements. We install the lock, set up the electronics, and test it through multiple cycles to ensure it’s engaging properly every time. You get the convenience of keyless entry without the headaches of a poorly installed system.
Most single-door installations take 20-30 minutes once we arrive with the correct hardware and tools.
That timeframe assumes your door is in decent shape and properly aligned. If we’re installing multiple doors, handling both sides of a door, or addressing underlying issues with door fit, it takes longer.
Complex installations like smart locks with electronic components, commercial-grade hardware, or situations where we’re repairing frame damage can take an hour or more per door. We let you know the expected timeframe when we assess the job.
The bigger time consideration is usually selecting the right hardware if you haven’t already chosen it. If you stop by our Prospect Park location, you can see options in person and make decisions quickly. We keep common residential hardware in stock for same-day installation.
If the mechanism inside is worn out or broken, replacement almost always makes more sense than repair.
Door knob mechanisms have small internal parts that wear from repeated use. Once they start failing, other components are usually close behind. Repairing one part often means you’re back to the same problem in a few months when the next piece fails.
Replacement makes especially clear sense if your hardware is over 10 years old, shows visible wear or corrosion, or if you can’t find replacement parts for your specific model. The labor cost to repair often approaches the cost of installing new hardware that comes with a warranty.
We do repair when it makes sense—if you have high-end hardware with available parts, or if the issue is something simple like a loose set screw or misaligned strike plate. We’re honest about which option serves you better long-term. We’re not trying to upsell you on replacement if repair actually solves your problem.
Yes. We use OEM parts from the actual manufacturers, not generic aftermarket components.
This matters more than most people realize. Aftermarket parts are manufactured to looser tolerances and often use cheaper materials. They might fit and seem to work initially, but they fail faster and sometimes cause additional damage to your door or frame.
OEM parts from Kwikset, Schlage, and Medeco are engineered to work together as a system. The springs, cylinders, latches, and strike plates are all designed for specific tolerances and performance standards.
When we install manufacturer parts, you get hardware that functions as intended and lasts as long as it should. You’re not calling us back next month because a cheap component failed. This is especially important for exterior doors and security hardware where reliability actually matters.
Absolutely. Rekeying new locks to work with your current keys is standard practice and usually the smart move.
When you replace door knobs or deadbolts, you don’t want to end up carrying separate keys for different doors. We rekey your new hardware to match your existing key, or we can rekey everything to work on one new key if you prefer.
This is particularly important for new Brookhaven homeowners who don’t know how many keys are floating around from previous owners. We can rekey or replace all your door hardware so you’re starting fresh with keys only you control.
We also set up master key systems if you want fewer keys on your ring. One key can open multiple doors while still allowing individual keys for specific doors. This works well for homeowners who want to give contractors or cleaning services access to certain areas without handing over keys to everything.
