Major carriers refuse new policies and renewals on homes with un-remediated aluminum branch wiring — it's a known fire-risk profile and a standard exclusion. A PE-sealed Alumiconn certification from a Missouri-licensed engineer is the exact document underwriters look for to clear the file.
Aluminum wiring isn't always disclosed at policy origination. Insurers catch it through several specific channels, and once it's in the carrier's notes, it's not coming back out without remediation evidence.
The carrier's underwriting system flags pre-1974 homes for an exterior inspection. The inspector spots aluminum at the service panel or in unfinished spaces and notes it in the file.
A long-time policyholder's renewal triggers a CLUE-report scan. If aluminum wiring is on the home's history, the renewal is conditioned on proof of remediation.
You shop the policy and a new carrier's binder is conditioned on remediation. The CLUE report or a fresh inspection surfaces the aluminum.
An unrelated claim (water, wind, roof) triggers a property inspection. The adjuster's report flags the aluminum — renewal goes to remediation hold.
In 2025 our Alumiconn certifications were accepted on first submission by every major carrier we encountered. No re-submissions, no supplementary requests. The combination of PE seal, UL 486C reference, and device-by-device documentation is what underwriters need.
→ Carrier not listed? Almost always still accepts. Submit the same package — we'll handle any underwriter follow-ups.
Carriers reject submissions that are missing PE seals, missing device counts, or missing UL listing references. Our package addresses all three by default — nothing supplementary required.
Cover page with engineer's seal, license number, signature date. Narrative on the remediation method, UL 486C reference, scope of inspection.
Every receptacle, switch, light fixture, and panel termination listed with location, connector model, torque verification, polarity check.
Every device documented with at least one photo showing the Alumiconn connector installed. Indexed to log entries.
One-page letter addressed to the named underwriter (if known), referencing your policy number and stating the remediation was completed per UL 486C standards.
Pricing is by home size and device count — no surprise charges, no negotiation. Quote returned same business day with the exact figure for your address.
Single-story ranch, smaller bungalow, condo. Most one-bath homes fall in this tier.
Two-story or large ranch, three-bedroom, finished basement. The most common home size in our coverage area.
Larger custom homes, multiple finished levels, multi-zone wiring. Includes subpanel inspection if present.
→ Rush 24–48hr surcharge: +$195 to +$295 depending on schedule density. Electrician's connector install is billed separately by your electrician.
Yes — this is one of our most common pre-emptive use cases. Once the cert is in your file, it's permanent and removes the renewal-cycle risk entirely. The Alumiconn certification doesn't expire, so investing in it once protects you against renewal-time discovery for as long as you own the home.
Yes. The phrase varies slightly by carrier (you'll see "PE certification of aluminum-wire remediation", "engineer's report", "professional engineer's letter") but they all mean the same document: a PDF sealed by a licensed PE certifying that the aluminum-wiring connections in the home have been remediated to a UL-listed standard. Our cert satisfies the language regardless of how it's worded in your file.
No. Insurers require engineering certification — the work has to be inspected and verified by a licensed PE, not by the installer. This is the industry-standard separation of duties (the installer can't certify their own work). Most carriers explicitly reject invoices and installer letters as substitutes.
If you're staying with the same carrier and they haven't re-flagged you, possibly not. But the moment you switch carriers, shop the policy, or have a covered claim trigger a property review, the wire-nut remediation will get flagged again — it's not UL-listed for aluminum-to-copper transitions. We see this monthly with policyholders who had old wire-nut work re-rejected by a new carrier.
The Alumiconn cert is the modern, UL-listed, permanently-accepted solution.
Most carriers don't surcharge specifically for aluminum wiring once remediated — the cert moves the home to "wired" status in the underwriting file. A small number of carriers maintain a modest surcharge regardless; if you find one, switching to a different carrier post-cert is straightforward since the cert moves with the home.
