Aluminum Wiring Modification
Staging the work keeps a family in the house while it happens. Aluminum branch wiring is a termination problem, not a wire problem, and the accepted remedy is far smaller than a full rewire.
Aluminum Wiring Modification 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.
A number follows a measurement here, never a guess. You get told what the reading was and what it means before any work is agreed, including on the days when the answer is one loose connection.
Permitted and inspected where the address requires it, labeled at the panel, and done by the person who diagnosed it rather than handed down a chain.
When people call about this
- Warm switch plates
- An inspector’s note on an older home
- Aluminum branch wiring from the 60s or 70s
- Circuits that dim when anything starts
Why people choose Clint for it
Nobody here earns more by finding more. That is the structural reason the small answer gets given when the small answer is true.

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.

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.
Grounding is usually the real gap
The thing that most often fails an older home’s inspection is not the wire, it is the absence of an equipment ground. Two-prong outlets are the visible symptom.
Depending on what is in the wall, that can mean GFCI protection on existing circuits, a dedicated ground run, or replacement. The measurement says which, and it changes room by room in the same house.

Why aluminum branch wiring is its own problem
Aluminum expands and contracts more than copper under the same load, so a connection that was tight when the house was built works itself loose over decades. The failure happens at the termination, inside a box, which is why it shows as a warm cover plate or an outlet that stops working intermittently rather than a breaker that trips. The wire in the wall is usually fine. The joints are the hazard.
The accepted correction is a listed repair at every termination rather than tearing the aluminum out: a short copper pigtail joined to the aluminum with a connector listed for the purpose, so the device itself sees copper. Done properly it is permanent and it satisfies inspectors and insurers who ask about aluminum before writing a policy.
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.

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.
“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.

Aluminum Wiring Modification across the metro
The same job is not the same job in every part of this metro. Same trade across five jurisdictions out of O’Fallon, with a different inspection process in each.
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
Much of this stock is two and four family, which means shared services and panels that are rarely labeled accurately.
Lincoln County
Lincoln County is rural service: longer drops, well pumps and septic loads that city panels never carry, and outages that make backup power a practical purchase rather than a luxury.

Questions worth asking first.
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.
Can a rewire be done in stages?
Yes, zone by zone with the house powered throughout and each stage inspected before the next. That is usually how an occupied house is done.
