Home Addition Electrical Wiring
Inspection timing drives the rest of the trades on a remodel. New construction wiring is judged by the inspection, so it gets planned to pass the first time.
Home Addition Electrical Wiring in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Owner-operated by Clint Ehman. Seventeen years in the trade, four of them running his own shop.

What this work actually involves
The inspection is scheduled around the rest of the trade work so the project does not wait on electrical.
The measurement happens before the number. You hear what the reading says in plain words, then what it means, then what it will take to fix. Where the fix is small you are told that rather than sold past it.
Permits get pulled where the municipality asks for one, and the work is left ready for the inspector with the panel labeled. The same person does the diagnosis and the repair.
When people call about this
- An ADU on the plans
- A bathroom with one outlet
- A basement about to be finished
- A kitchen layout that moved
Why people choose Clint for it
There is no dispatcher taking a description for someone else to act on, and no commission riding on what the visit totals. The person who measures it is the person who fixes it.

Where this is done
O’Fallon first, then the rest of St. Charles County, St. Louis County and the City, and out to Lincoln and Warren. If you are just past that, the call is still worth making.

Panel capacity is the usual constraint
A finished basement adds lighting, receptacles, often a bathroom and sometimes a kitchenette. Each is modest; together they are a load the original service may not have.
The calculation happens before the framing, because finding out at inspection is expensive.
Everything is cheaper before the drywall
Rough-in is the one moment when circuits are nearly free to place. Afterwards the same change means opening a finished wall.
That is why the plan gets made against the finished room: where the television will sit, where the treadmill goes, whether the freezer ends up in the basement.
Wiring an addition against the whole house
An addition adds load to a service that was sized before it existed, so the calculation covers the whole house rather than the new rooms. Skipping that is how a new wing trips the main.
Rough-in is planned against the finished use, inspected before drywall, and the panel is relabeled for the house as it now is rather than as it was.
What makes this harder in older housing stock
Across this metro the recurring complications are predictable: no equipment ground, aluminum branch wiring from the mid-seventies, knob-and-tube buried in blown-in insulation, panels that have been added to several times, and splices in places the code has not allowed for decades.
Those turn a simple job into a decision about scope. The decision gets put to you with the reading behind it rather than made quietly and billed.
What gets left behind when the work is done
A labeled panel, accessible junctions, the old parts if you want to see them, and a straight account of anything found along the way that was not part of the call.
Where something else was found, you get told what it is and whether it needs doing now, later or not at all. That third answer is a real answer and it gets used.
“Clint came out installed me a large 200 amp panel put some new dedicated lines in my basement and garage he did great clean work all inspections passed he was thorough and knowledgeable. I will have him back out again.”

How the visit goes
- The call
The plans, the rooms, and what will actually be in them when it is finished.
- The measurement
Load calculation before framing, panel capacity, and a circuit plan drawn against the finished use rather than the label on the drawing.
- The finding
Whether the existing service covers the project, and what the rough-in needs to include so nothing is opened up twice.
- The work
Rough-in labeled and photographed before insulation, inspection timed around the other trades, devices and fixtures at finish, final inspection attended.
What the job includes
- Circuit plan drawn against the finished room, not the label on the plan
- Load calculation before framing, so capacity is known early
- Rough-in labeled and photographed before insulation
- Coordination with the other trades on inspection timing
- Device and fixture install at finish
- Final inspection attended
What it does not
- Framing, drywall and finishing
- Cabinetry and appliance supply
- Permit fees, which are passed through at cost
Work that is not electrical gets a referral, not a quote. Finished work is in the gallery. To book, pick a day.

Home Addition Electrical Wiring across the metro
Housing stock varies sharply across the counties here, and so does the work. Out of O’Fallon across thirty municipalities, where the permit process changes more than the work does.
Warren County
It is the far end of a roughly fifty mile radius, so visits get grouped rather than squeezed in. That affects the date, not the price.
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
Older stock that has been worked on repeatedly, so a panel here has often been added to three or four times by different hands.
The full footprint, county by county, is on the service areas page.
Questions worth asking first.
How many circuits does a kitchen need?
More than most older kitchens have: counter receptacles, dishwasher, disposal, microwave, refrigerator and range each have requirements. The plan is drawn against the appliances actually being installed.
When should the electrician come in on a remodel?
Before the drywall. Rough-in is when circuits are cheap to place, and that is the one chance to put them where the finished room will actually be used.
Will my panel carry a finished basement?
That is the question to answer first. A finished basement adds lighting, outlets and often a bathroom or a freezer, and the load calculation shows whether the existing service covers it.
Do you pull permits?
Where the municipality requires one, yes, and the work is left ready for inspection with the panel labeled and junctions accessible. Requirements genuinely differ across this metro, which is why it is established per address rather than assumed.
How long have you been doing this?
Clint has seventeen years in the trade and has been running his own shop out of O’Fallon since 2022.
