Flickering Lights Diagnosis
Intermittent problems are the hardest and the most important to reproduce. Most electrical faults announce themselves before they fail, in heat, smell or a breaker that keeps tripping.
Flickering Lights Diagnosis in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.

What this work actually involves
The fault is located with a meter and a plan rather than by swapping components until something changes.
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
- An inspection report before a closing
- Half the house without power
- Warm cover plates
- A burning smell near a panel or outlet
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 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.

Which symptoms are urgent and which are not
Heat at a device or panel, a burning smell, visible arcing, water in electrical equipment, or losing power to roughly half the house: those move to the front of the day, because each one means something has already failed or is actively failing.
A breaker that tripped once, a dead outlet, or a flickering fixture can be scheduled. Being told which category you are in is itself useful, and it is free.
The symptoms that should never wait
Heat at a cover plate, a smell of hot plastic, and a breaker that will not stay set are the three that justify a same-day call. All three describe energy going somewhere it should not.
Flickering across unrelated circuits belongs in the same group, because it points at the service or the neutral rather than at one room.

What flickering actually tells you
Flickering in one fixture is usually that fixture or its dimmer. Flickering across the house, especially when a large motor starts, points at a loose connection upstream: a lug, the main, or the service neutral.
That distinction decides urgency. A failing service neutral can produce odd voltages across the house and damage equipment, so a whole-house flicker gets measured at the panel first.
Why a diagnosis is worth paying for
A measurement that comes back saying the service is fine and one circuit is overloaded saves the cost of a service upgrade. That is the most common outcome of a load calculation, and it only has value because it is honest in both directions.
An inspection that never finds anything is not a good inspection and neither is one that always finds plenty. What makes it useful is that the finding is a reading you can check.
What the price actually depends on
Three things move the number on almost every job: how far the run has to travel and what it passes through, whether the existing panel has space and the service has capacity, and whether the municipality wants a permit and an inspection. None of those is visible from the phone call, which is why the measurement comes before the quote.
What does not move it is urgency theatre. There is no inflated figure waiting to be discounted, and no bundle built so the thing you called about cannot be bought on its own.
“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
What you are seeing, smelling or hearing, and when it started. Heat and smell move you up the day.
- The measurement
Reproduce the symptom, then divide the circuit until the fault is on one side of the split. Measurement at the panel and at the point of failure.
- The finding
What it was, with the reading. Including when the answer is one loose connection rather than the rewire you were braced for.
- The work
Correction scoped to the finding, permitted and re-inspected where the municipality requires it, and documentation you can hand to an inspector or a buyer.
What the job includes
- Reproducing the symptom before anything is replaced
- Measurement at the panel and at the fault
- A plain-words finding with the number that supports it
- Correction scoped to the finding, nothing bundled
- Permit and re-inspection where a municipality requires it
- Documentation you can hand to an inspector or a buyer
What it does not
- Replacing parts that test sound
- Opinions where a measurement is possible
- Work outside electrical, though we will say who to call
If the fix belongs to another trade, you get the name of one rather than a price from this one. There is a gallery of finished jobs, and a form if that is easier than calling.

Flickering Lights Diagnosis 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. Louis City
Century housing, its own permitting authority, and occupancy inspections that decide a lot of the calls.
Lincoln County
Rural properties where the panel is fine and the two hundred foot run to the barn is the actual job.
Warren County
Two kinds of work share the same ZIP codes here: recent subdivisions with modern wiring and tight services, and farm properties carrying several eras at once.
The whole working radius is mapped on the service areas page.
Questions worth asking first.
Can you handle the items on my inspection report?
Yes. Send the report. The items get corrected, permitted where the municipality requires it, and re-inspected so the file closes before your closing date.
My lights flicker across the whole house. Is that urgent?
Potentially. A whole-house flicker, especially when a large motor starts, can mean a failing service neutral, which can damage equipment. That gets measured at the panel before anything inside is touched.
Half my house has no power. Is that a breaker?
Usually not. Losing roughly half the house is the signature of a lost leg of the service or a failing neutral, and it gets measured at the service entrance first.
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.
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.
