Home Surge Protection
Backup power is bought for one week a year and judged on that week. Surge protection is the cheapest insurance in the house, and whole-home protection works differently from a power strip.
Home Surge Protection in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.
Owner-operated: the person who answers the phone is the person who measures it.

What this work actually involves
Surge protection is installed at the panel where it can clamp what comes in, not just at the device.
Nothing gets quoted off a description. The reading comes first, because a symptom has several possible causes at very different prices and only a measurement separates them.
Where a permit and an inspection are required they happen, and the site is left ready for them. One person carries the job from the first call to the final test.
When people call about this
- A sump pump and a finished basement
- Portable generator cords through a window
- A home office that cannot go dark
- Electronics lost to a storm
Why people choose Clint for it
The diagnosis and the repair are the same person’s work, which is why the explanation you get is first-hand rather than relayed.
Five point zero from 94 Google reviews, A+ with the BBB since December 2022, and seventeen years in the trade behind it.
Where this is done
Out of O’Fallon across five jurisdictions: St. Charles County, St. Louis County, St. Louis City, and Lincoln and Warren counties. About fifty miles in any direction.

The transfer arrangement is the safety-critical part
Whatever the source, the transfer has to make feeding the utility physically impossible. That is a transfer switch or a listed interlock, and it is what protects the crews working to restore your street.
A cord into a dryer outlet does not do that, and it is the single most dangerous thing homeowners improvise during an outage.
Surge protection that actually works
Whole-home surge protection installs at the panel, where it can clamp what arrives on the service conductors. A power strip protects one device from what is already inside the house.
Both have a place. Layered protection, panel plus point-of-use for sensitive electronics, is what survives a Missouri storm season intact.
Where surge protection belongs
Most damaging surges are not lightning. They come from the utility side and from large motors inside the house cycling off, which is why a whole-house device at the panel catches more events than a strip at the television.
The panel device handles the big transients, and point-of-use protection at expensive electronics handles what gets past it. Layered that way it works; a strip alone does not, and a panel device alone leaves sensitive equipment exposed.
Who actually does the work
Clint Ehman does the diagnosis and the repair himself. There is no salesman writing a scope for a technician to execute, and nobody paid on what the visit totals.
Seventeen years in the trade, four of them running his own shop out of O’Fallon, licensed, bonded and insured with workers compensation coverage, 5.0 from 94 Google reviews, and A+ BBB accreditation held since 2022.
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.
“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 need to keep running and how often the power goes out where you are.
- The measurement
The loads you named, added up honestly, and the panel’s capacity to feed a transfer switch or interlock.
- The finding
A size and a configuration, with the cost difference between keeping the essentials on and running the whole house made plain.
- The work
Unit sited, circuit run, transfer switch or interlock installed so back-feeding is impossible, inspected, then a walkthrough of starting and transferring with you present.
What the job includes
- Load selection: what has to run, what can wait
- Generator or inlet sized to the chosen loads
- Transfer switch or interlock so back-feeding is impossible
- Pad or mounting, and the circuit to it
- Permit and inspection where required
- A walkthrough of starting and transferring, in person
What it does not
- Gas piping, which is the plumber’s trade
- Concrete pads beyond a prefabricated base
- Generator servicing contracts
Anything that is not an electrical problem gets identified as such and handed on. See finished work, or say what the house is doing.

Home Surge Protection across the metro
Five jurisdictions, five different sets of conditions. What an inspector looks at first differs by address here, which shapes the job as much as the house does.
St. Charles County
The subdivisions here were wired correctly for what houses drew at the time. A charger, a heat pump and a finished lower level later, the arithmetic no longer works out.
St. Louis County
This is where the genuinely old wiring lives: cloth insulation, no equipment ground, fuse panels and the mid-seventies aluminum. Each has an accepted remedy rather than requiring a whole-house rewire.
St. Louis City
Brick with plaster over lath, party walls that limit where a run can go, and a hundred years of electrical layers in the basement.
Thirty towns across five jurisdictions, all on the service areas page.
Questions worth asking first.
Can I use a generator cord into a dryer outlet?
No. That back-feeds the utility and endangers the crews working your line. A transfer switch or a listed interlock is what makes that physically impossible.
Battery or generator?
A battery is silent and instant for a limited number of hours; a generator runs as long as it has fuel. How long your power usually stays out decides it.
What size generator do I need?
It depends on what has to keep running. A well pump, a sump pump and a furnace need very different capacity from a whole house, and picking the loads deliberately keeps the cost sensible.
