Everything else you might be wondering.

Not directly — we connect you with a vetted St. Louis electrician from our referral network who installs the Alumiconn connectors, and our P.E. then independently inspects the work and issues the PE-sealed certification. Separate roles, same standard: keeping install and certification in different hands is what insurers and lenders expect to see.

The referral costs you nothing, and every electrician in the network installs to the UL-listed torque spec.

If the assessment identifies installation concerns, we document the findings for review by the electrical professional. Confirm the required corrections and follow-up inspection scope before arranging additional work.

Typical residential inspection is 1–3 hours on site, depending on device count. Small ranches with 20–30 devices: ~1 hour. Medium homes with 30–50 devices: 1.5–2 hours. Larger homes with finished basements, multiple levels, or subpanels: 2.5–3 hours.

Yes — most homeowners are. Our P.E. is happy to walk through what they're checking and answer questions. For active-deal jobs we sometimes coordinate access through the listing agent's lockbox without the homeowner present; either works.

Confirm report delivery and any urgent deadline when requesting the inspection. The completed PDF can be sent to the insurer, lender, or other recipient you identify.

Yes. Alumiconn is UL 486C-listed for aluminum-to-copper transitions, and a PE-sealed certification from a Missouri-licensed engineer is the documentation every major carrier requires.

See For Insurance for the full carrier list.

The Alumiconn is UL-listed for the design life of the building. King Innovation, the manufacturer, designs the connector for a service life of 50+ years under normal residential conditions. Once installed and certified, you don't need to revisit the work — this is a one-time remediation.

Wire nuts — even the "Al/Cu"-labeled purple-cap varieties — are not UL-listed for aluminum branch-circuit transitions. The listing covers copper-to-copper only. Insurers and lenders know this and will reject wire-nut remediation on sight, even if it was done years ago and the home has been quietly insured.

See Methods Compared for the full breakdown.

We do certify COPALUM installs when we encounter them — the method is excellent and UL-listed. The problem in our coverage area is installer scarcity: COPALUM requires a proprietary hydraulic crimper that only a handful of licensed installers in metro STL carry, and they're typically booked 1–3 weeks out. That works for non-urgent jobs; it kills active-deal timelines.

Alumiconn can be installed by any qualified electrician with stock tools, which is why it's our default recommendation.

Request a property-specific quote with your address, available electrical repair records, and the insurer or lender’s exact requirement.

The electrician's connector install is billed separately by your electrician. Submit the quote form for an exact figure for your address.

The engineering assessment and electrical installation are separate scopes. If you need an electrician, ask about installation help and confirm each professional’s deliverables.

For multiple properties or recurring inspections, send the anticipated scope, locations, and timing. Ask about a written proposal and coordinated scheduling for your team.

See For Pre-Listing for portfolio scheduling details.

If you are unsure whether the home has aluminum branch-circuit wiring, ask about a confirmation assessment before arranging remediation. A qualified professional should identify the wiring and explain the next step.

Standard 24 hours from completed field visit. Rush options available with surcharges. The bottleneck is usually the electrician install, not us — if your install is already done, we can typically be on site within 2 business days and have the sealed PDF in 24 hours.

For active deals with close dates under a week out, call us directly at (573) 275-7647.

Field visits are Monday–Friday during business hours by default. Weekend visits available for rush jobs on a surcharge basis. Report writing and PDF sealing happens evenings and weekends as needed — the 24-hour clock doesn't stop on weekends.

Tight but yes — this is what rush scheduling is for. Call us directly rather than using the form. If the electrician install hasn't happened yet, we coordinate with a referred electrician to compress the whole stack. We've delivered same-week certs on Friday afternoons for Monday closes.

All major U.S. carriers we've encountered. 2025 first-submission acceptance: State Farm, USAA, Allstate, Liberty Mutual, Farmers, Travelers, AAA, Country Financial, Erie, Auto-Owners, Nationwide, Safeco — all 100%. Smaller and regional carriers almost always accept; if a follow-up is needed, we handle the underwriter correspondence directly.

Yes. Our cert satisfies FHA HUD 4000.1 II.A.3, Fannie Mae / Freddie Mac conventional underwriting standards, VA Minimum Property Requirements § 13.10, and USDA RD Handbook 1-3550. The cover letter we attach references the specific underwriting language for your loan product.

See For Refinance for the loan-product breakdown.

Yes. Direct-to-underwriter routing is standard practice. Provide the underwriter's email (or the loan processor's contact) and we email the PDF directly with your loan number or policy number in the subject. CC'd to you for the record. This typically shaves 1–2 business days off the timeline.

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.

Scapular Engineering, P.E. is licensed in Missouri, Arkansas, Illinois, Kansas, Iowa, Nebraska, and Indiana. Every report in the Scapular Engineering network — including STL Alumiconn, Midwest FHA Inspection, Midwest MFG Inspection, PFGMH & Affixation, and Affix Report — is sealed by our P.E. You can verify MO licensure at the state board website.

The aluminum-wiring practice is part of the broader Scapular Engineering inspection firm founded in 2018. Our P.E. has been PE-licensed since 2019, with a residential inspection focus since 2018 and a dedicated aluminum-wiring sub-practice since 2021. 2025 volume: 184 homes certified.

Yes. $2 million Errors & Omissions liability coverage through an A+ rated carrier. Every PE-sealed report is backed by the policy; that's part of why insurers and lenders accept the cert as a primary remediation document.
