If a home inspector flagged aluminum branch-circuit wiring and now your insurer, lender, or buyer won't budge — an Alumiconn connector remediation certified by a licensed P.E. is the document that clears the hold. We do this in St. Louis County and St. Charles County. Every job is signed and sealed by a licensed Scapular Engineering P.E.
Homes built in St. Louis roughly 1965–1973 were often wired with solid aluminum branch circuits. The wiring itself isn't illegal and the house doesn't need rewiring — but the connections loosen and overheat over time, and insurers, lenders, and buyers know it. That's why it gets flagged.
Most major carriers flat-out won't write a new policy on a home with un-remediated aluminum wiring. Without insurance, there's no close.
FHA, VA, and conventional underwriters frequently condition funding on proof of remediation — which means a licensed engineer's seal on a report.
The home inspector calls out aluminum wiring in the report, and now the buyer's agent is asking for remediation as a condition to close. The clock starts.
The permanent fix is not a full rewire. It's an approved connector called Alumiconn that joins each aluminum wire to a short copper "pigtail" that lands on the device. Installed at every device in the house, then inspected and certified.
A licensed electrician — typically your preferred vendor, though we can recommend one — installs Alumiconn connectors at every outlet, switch, and fixture carrying aluminum wire in the house.
Our P.E. personally inspects each connector installation on site — pulling covers, verifying torque, checking polarity, documenting by circuit and device. Photo appendix included in the report.
Engineering report with PE stamp, signature, license number, and date. Delivered to you and your insurer / lender. Carriers accept it for binding; lenders clear the condition.
This service is bounded to St. Louis County and St. Charles County, Missouri — because our P.E. performs every Alumiconn inspection personally, and those two counties have the densest stock of pre-1975 housing in the region.
If your property is inside the zone, we can usually schedule the inspection within 2–4 business days of your quote. Rush scheduling (24–48 hrs) is available for an active-deal surcharge.
If your property is outside the zone — Jefferson County, Franklin County, or over the river in Illinois — we can't perform the inspection, but we can refer you to another PE who handles this service in your market.
Copper prices spiked in the late 1960s, pushing residential contractors to aluminum for branch circuits. By mid-1974, code changes and insurance pressure had forced aluminum out of new residential construction. That window — about eight years — is the bulk of affected housing stock.
Here's what the full timeline looks like from the moment you call us. Everything before Step 03 is paperwork and coordination; Step 03 is the only hands-on day.
Use the form below or call. Tell us the property address, which insurer / lender is blocking, and whether this is an active deal with a close date. We'll confirm scope and return a written quote the same business day.
Your electrician (or one we refer) installs UL-listed Alumiconn connectors at every device carrying aluminum wire. We don't do the install ourselves — we inspect and certify it. Typical labor is 1–2 days for an average home.
Every device carrying aluminum wire gets its cover pulled, torque verified, polarity checked, and the installation photo-documented. Typical residential inspection is 1–3 hours on site depending on circuit count.
Our P.E. writes the narrative, reviews the photo appendix, signs and seals the PDF, and emails it to you and your lender / insurer directly. License number and MO stamp appear on the cover and cert pages.
Your insurer binds, your lender clears the loan condition, your buyer's agent signs off. Deal closes on schedule.
Three minutes. Written quote back the same business day with scheduling window. If your property is outside our two-county zone we'll tell you right away — no wasted time.
No — we inspect and certify. A licensed electrician installs the Alumiconn connectors; our P.E. inspects the install and issues the PE-sealed certification. Keeping the install and the certification in different hands is the industry-standard separation and it's what insurers expect to see.
If you don't have an electrician, we can refer one.
Yes. Alumiconn is UL-listed for aluminum-to-copper connections, and a PE-sealed certification from a licensed engineer in the state of Missouri is the documentation every major insurer requires. Our 2025 acceptance rate on first submission was 100%.
The certification inspection itself is priced on the number of devices that need to be opened and verified — typical residential ranges roughly $650–$1,100 for the PE certification alone. Your electrician's install bill is separate and depends on device count.
Submit the quote form for an exact figure — we respond same business day.
Post-1974 homes in STL almost never have aluminum branch-circuit wiring — code changes and insurer pressure drove it out by mid-1974. If your home inspector is flagging "aluminum wiring" on a newer home, call us before scheduling anything; it's worth confirming the finding first.
If we find issues with the install — missed devices, loose torque, wrong connector, polarity issues — we document them and send the list to your electrician for correction. We re-inspect and certify once the corrections are made. Re-inspection is included in the original fee up to one return visit.
Yes. Scapular Engineering is operated by a licensed Professional Engineer in Missouri, Arkansas, Illinois, Iowa, and Kansas. Every report in the network — including this one — is PE-sealed personally on every delivery. You can verify MO licensure at the state board website.
No more weeks of back-and-forth with your insurer, lender, or buyer's agent. A PE-sealed Alumiconn certification is the document that ends the conversation.
STL Alumiconn is one of six PE-sealed inspection practices operated by Scapular Engineering, P.E. The network covers Midwest housing, FHA, manufacturing, and settlement-package services from a single licensed engineer.
