Network Cable Installation
Cameras and doorbells need power planned, not improvised. Most smart switch failures are a missing neutral, not a bad device.

What this work actually involves
Devices are wired to work when the internet does not, because a doorbell that needs a cloud is a doorbell that fails.
The order is always the same: reproduce it, measure it, say what the number means, fix the thing the number points at. Nothing gets bundled on the way past.
Permits and inspections happen where the municipality requires them, and the panel is left labeled. One person does all of it.
When people call about this
- Smart switches that drop offline
- A doorbell with no transformer
- Cameras on extension cords
- A remodel wanting structured wiring
Why people choose Clint for it
Nobody here earns more by finding more. That is the structural reason the small answer gets given when the small answer is true.

Where this is done
O’Fallon and the surrounding St. Charles County suburbs, out through St. Louis County and St. Louis City, and into Lincoln and Warren counties. Roughly a fifty mile radius.

The neutral problem
Most smart switches need a constant neutral to power their own electronics, and a great many older switch boxes were wired with only a switch leg. That single fact decides which devices can physically go in a given wall.
Where there is no neutral, the options are a device designed to work without one, a new run, or a different control point. Which applies gets established at the box rather than guessed from the product page.
Box depth, which nobody checks until it is too late
Smart devices are deeper and bulkier than what they replace, and the existing box is frequently too shallow once the conductors are folded back in. Forcing it is how terminations get stressed.
Depth and box fill get checked first, and where a box is too small the honest answer is a deeper box rather than a device crammed in.
Cabling a house for the long run
The places worth cabling are the ones that will not move: the television wall, the office, the access point locations and wherever the equipment lives.
Everything lands at a single patch point, labeled, so changes later are a patch cord rather than a new run.
Why the diagnosis comes before the quote
A symptom has several possible causes with very different prices, and the only thing that separates them is a measurement. Quoting the expensive one covers the risk; quoting the cheap one and finding the expensive one mid-job is worse.
So the reading happens first, you are told what it says, and then the work is scoped to it. Where the honest answer is the small repair, that is the answer you get, even when the larger job pays better.
What is worth automating and what is not
Lights on a schedule, a thermostat that knows when the house is empty, and a lock you can check from elsewhere all earn their keep. Novelty devices get used for a month.
Deciding that before the wiring is planned keeps the install small and the result something that is still in use in three years.
“Clint did an excellent job installing two bathroom exhaust fans. He installed high-quality fans that were far superior to the ones I had purchased from a big box store. I highly recommend his services.”

How the visit goes
- The call
Which device, which wall, and what it needs to do when the internet is down.
- The measurement
Whether the box has a neutral and the depth for the device, what the existing load is, and the signal at that wall.
- The finding
Which devices will actually work there. Sometimes the answer is a different device, sometimes a transformer, sometimes a new run.
- The work
Wired for local control, runs labeled at both ends, tested on your network rather than at the wall.
What the job includes
- Checking the box for a neutral and for depth before anything is ordered
- Devices wired so they work when the internet does not
- Runs labeled at both ends and documented
- Transformers where an older house lacks one
- Low-voltage terminated in a panel, not a knot
- Testing on the actual network, not just at the wall
What it does not
- Ongoing app and account support
- Internet service and router configuration
- Subscription cameras we have not installed
Anything outside electrical, you will be told who to call rather than sold it. Recent jobs are worth a look before you call.

Network Cable Installation across the metro
The same job is not the same job in every part of this metro. Out of O’Fallon across thirty municipalities, where the permit process changes more than the work does.
St. Charles County
Modern wiring, undersized services. That combination defines most of the work in this county, and it makes the load calculation the deciding document rather than a panel inspection.
St. Louis County
Dozens of municipalities, each with its own occupancy inspection and its own thresholds. Knowing which authority has the address matters as much as knowing the house.
St. Louis City
The City is an independent city, not part of the County, and it runs its own permits and inspections. Assuming county process here is a common and expensive mistake.
The whole working radius is mapped on the service areas page.
Questions worth asking first.
Can you wire a doorbell camera?
Yes, including the transformer most older houses lack. A hardwired doorbell keeps working when the batteries and the Wi-Fi do not.
Will my smart switches work if the internet goes down?
Devices that keep local control will. Cloud-only devices become a wall plate, which is worth knowing before they go in.
Does my box have room for a smart device?
Smart devices are deeper than what they replace, so box depth and fill get checked first. Sometimes the honest answer is a different device.
Are you licensed and insured?
