Grounding System Installation
What gets left in the wall matters as much as what comes out. Aluminum branch wiring is a termination problem, not a wire problem, and the accepted remedy is far smaller than a full rewire.
Grounding System Installation in O’Fallon and across St. Charles, St. Louis, Lincoln and Warren counties.

What this work actually involves
Grounding is brought up to current requirements, which is usually what makes the difference for a buyer’s inspector.
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
- Cloth or rubber insulation at the panel
- Warm switch plates
- An inspector’s note on an older home
- Aluminum branch wiring from the 60s or 70s
Why people choose Clint for it
One person does the diagnosis and the repair, so nothing is lost between a salesman and a technician, and nobody is paid to sell past the finding.

What is actually wrong with old wiring
Knob-and-tube was installed competently for the loads of its day, and plenty of it tests sound. Its weaknesses are specific: no equipment ground, brittle insulation at fixtures where heat collected, and a serious problem if someone has buried it in blown-in insulation.
Aluminum branch wiring from the 1960s and 70s is different again. The conductor is fine; the terminations creep and loosen. The accepted remedy treats those connections, which is a far smaller job than a rewire.
How a rewire is staged
A rewire is disruptive, so it gets staged. Circuits are replaced zone by zone with the panel reworked once, which keeps the house livable and means the family is never without the kitchen and the bathroom at the same time.
Fishing walls beats opening them wherever the framing allows. Where drywall has to come out, it comes out in planned places rather than wherever is convenient.
Grounding and bonding, which are not the same thing
Grounding gives fault current a path back to the source so a breaker can see it and trip. Bonding ties metal parts to the same potential so there is no voltage between two things you can touch at once. Houses here are frequently short on one or both.
The electrode, the conductor sizing, the bonding at the water and gas pipes and the connection at the panel all get verified rather than assumed, because a ground that is not connected looks exactly like one that is.
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.
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.
“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
What is in the walls, how old the house is, and whether this is for safety, a sale or a remodel. The reason changes the scope.
- The measurement
Testing at accessible terminations and devices, checking for an equipment ground, and looking for the specific hazards: buried knob-and-tube, brittle insulation at fixtures, creeping aluminum connections.
- The finding
Honest scope. Wire that tests sound stays. Where a rewire is the answer it is staged, and you are told what order and how long the house is affected.
- The work
Zone by zone, fishing walls rather than opening them where the framing allows, grounding brought current, rough-in photographed before anything closes up.
What the job includes
- Inspection of every accessible termination, which is where failures live
- Testing before anything is removed, so sound wire stays in the wall
- Staged replacement room by room where a rewire is the honest answer
- Grounding brought to current requirements
- Permit and inspection where required
- Photographs of the rough-in before anything closes up
What it does not
- Plaster and drywall finishing beyond patching access holes
- Insulation replacement
- Removing wire that is safe to leave in place
Work that is not electrical gets a referral, not a quote. Finished work is in the gallery. To book, pick a day.

Grounding System Installation across the metro
Where the house is changes what the work involves. What an inspector looks at first differs by address here, which shapes the job as much as the house does.
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.
St. Louis City
The City is an independent city, not part of the County, and it runs its own permits and inspections. Assuming county process here is a common and expensive mistake.
Lincoln County
Well and septic loads mean a failure is no water rather than an inconvenience, so those circuits get treated accordingly.
Every municipality covered is listed on the service areas page.
Questions worth asking first.
Does old wiring mean the whole house has to be rewired?
Almost never. Aluminum branch wiring is a termination problem with an accepted remedy. Knob-and-tube that tests sound and is not buried in insulation can often stay. The measurement decides it, not the age.
Will an inspector pass it?
That depends on grounding and terminations more than on the conductors. Those are the items that get corrected, documented and re-inspected so a file closes.
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.
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?
Licensed, bonded and insured, with workers compensation coverage, and accredited A+ with the BBB since 2022.
