What the houses here need
Wentzville sits in St. Charles County, which means 1990s and 2000s subdivisions, which means services sized before EV chargers and finished basements existed.
That shapes the work. Clint measures before he quotes, tells you what the reading says, and fixes the thing that is actually wrong. If the service is fine and one circuit is overloaded, you hear that.
Permits are pulled where Wentzville and St. Charles County require them, and the work is left ready for inspection. Requirements genuinely differ between municipalities here, which is worth knowing before a closing.
Why the panel is usually the first conversation
Most calls in Wentzville start somewhere else and end up at the panel, because the panel is where the capacity question gets answered. A tripping breaker, lights dimming when the furnace starts, or a new appliance that will not fit are all the same question asked three ways.
A load calculation settles it, and it settles it in both directions. Plenty of houses that feel short on capacity are comfortably carrying what they ask of them, and the real fix is one dedicated circuit rather than new service.
What changes when a house is being sold
Closings are where electrical problems become expensive, because an inspector’s written item turns into a negotiating position with a deadline attached. The items that come up around Wentzville are consistent: missing equipment grounds at two-prong outlets, protection absent in wet locations, panel labeling, and obsolete or over-stuffed panels.
Working from the written list keeps that short. Each item gets corrected, permitted where Wentzville requires it, re-inspected, and documented for the closing file rather than cleared verbally.
Older houses and newer appliances
The recurring combination around Wentzville is a house wired for the loads of its decade now running a heat pump, an induction range, a finished basement and a car charger. Nothing in the walls failed; the demand changed.
That is a measurement problem rather than a guess. The load gets calculated against the service, and the answer is frequently load management or one new circuit rather than the service upgrade people brace for.
Storms, outages and backup power
Summer storms through this part of Missouri take lines down, and the backup power conversation in Wentzville is usually about a short list rather than the whole house: the furnace blower, the refrigerator, a sump or well pump, some lighting.
Written down and added up honestly, that list is smaller and cheaper than running everything. Whichever size is chosen, the transfer has to make back-feeding the utility physically impossible, which means a transfer switch or a listed interlock.
Getting a straight answer about urgency
Some things in Wentzville move to the front of the day and some genuinely wait. Heat or a burning smell at a panel or an outlet, visible arcing, water in electrical equipment, or losing power to half the house: those are now.
A breaker that has tripped once, a dead outlet, a fixture that flickers: those can be scheduled. You get told which category you are in rather than being sold urgency.
What a service call in {city} actually costs you in time
The honest variable is not the hourly rate, it is whether the job needs a utility disconnect or a permit office. A device, a breaker or a circuit addition is usually a single visit. A service change means coordinating Ameren for the disconnect and a municipal inspection, which puts it on a scheduled day.
Knowing which one you have before anything is booked is most of the value of the first phone call, and it is why the symptom matters more than the guess at the cause.
Grounding, which most older {city} houses are short on
An equipment ground gives fault current a path back so a breaker can see it and trip. Two-prong outlets have none, and a three-prong outlet retrofitted onto two-wire cable has the appearance of one without the function, which is worse because it reads as safe.
That gets tested rather than assumed, because a ground that is not connected looks exactly like one that is. Where a ground is missing, the correction is either a real one or GFCI protection with the outlet labeled as the code allows, and you are told which applies.
“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.”

Nearby towns
Clint covers the whole county out of O’Fallon. Requirements differ between municipalities, so the process changes from one of these to the next even where the work does not.
Every service is listed on the services page, the rest of the area on St. Charles County, and finished work in the gallery. To book, pick a day.
Questions worth asking first.
Will you have to open my walls?
Wherever the framing allows, runs get fished instead. Where a wall genuinely has to be opened you are told before the work starts, and the patch is left ready for paint.
Is a transfer switch required?
Yes, for any permanent standby system. It stops the generator back-feeding the utility, which is what protects the line workers restoring your street.
Do I need a bigger service, or just more space in the panel?
Those are different problems. A full panel with spare capacity takes a sub-panel or tandem breakers. A panel that is out of capacity takes a service upgrade, and the load calculation tells us which one you have before anything is ordered.
Who actually shows up?
Clint Ehman. Infinity Electric is owner-operated, so the person who answers the phone is the person who measures your panel and pulls the permit. There is no dispatcher and no commissioned salesman.
Are you licensed and insured?
