New Construction Electrical Wiring
Everything is cheaper before the drywall. A remodel is the one chance to put the circuits where the room will actually be used.
New Construction Electrical Wiring in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Clint Ehman, seventeen years in the trade, running Infinity Electric out of O’Fallon since 2022.
5.0 from 94 Google reviews · BBB A+ since 2022
What this work actually involves
Circuits are planned against the finished room, including the loads nobody mentions until later, like a freezer or a treadmill.
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
- A basement about to be finished
- A kitchen layout that moved
- An addition with no panel capacity
- A garage becoming a workshop
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.
Seventeen years in the trade and four running Infinity Electric out of O’Fallon, with 5.0 from 94 Google reviews and BBB accreditation since 2022.
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.
Rough-in that does not get opened up twice
The load calculation happens before framing, against what will actually be in the rooms rather than what the drawing labels them. Getting that wrong means opening finished walls later.
Rough-in is labeled and photographed before insulation, inspections are timed around the other trades, and devices and fixtures go in at finish with the final inspection attended.
Permits, inspections and why they vary here
Requirements genuinely differ across this metro. O’Fallon, St. Charles, St. Peters, the St. Louis County municipalities and St. Louis City each run their own process, and what one treats as a minor repair another permits and inspects.
Work that needs a permit gets one, and work that needs an inspection is left ready for it with the panel labeled and the junctions accessible. That matters most before a closing, when an inspector’s written item becomes someone’s negotiating position.
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.
“Infinity came out for same day service after an electric line had been cut in my yard. He was able to locate and correct it very quickly, eliminating any risk of injury or additional power outage.”

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.
Related remodel & new construction work
New Construction 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
Warren County mixes newer builds with older farm properties, and generator work comes up more often there than it does in town.
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.
See which towns fall inside the radius 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.
Are you licensed and insured?
Licensed, bonded and insured, with workers compensation coverage, and accredited A+ with the BBB since 2022.
Where do you work?
Out of O’Fallon across St. Charles County, St. Louis County, St. Louis City, and Lincoln and Warren counties, roughly a fifty mile radius.
