§ 01 · THE CERTIFICATION PROCESS

How the inspection and seal work.

No — we inspect and certify, we don't install. A licensed electrician installs the Alumiconn connectors; our P.E. inspects the install and issues the PE-sealed certification. Keeping install and certification in different hands is the industry-standard separation of duties and what insurers and lenders expect to see.

If you don't have an electrician lined up, we can refer one in the STL metro.

If we find issues during the PE inspection — missed devices, loose torque, wrong connector, polarity errors — we document them with photos and forward the fix-it list to the electrician. We re-inspect once the corrections are made. Re-inspection is included in the original fee for one return visit; beyond that, additional re-inspections are quoted at $185 per visit.

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.

Standard 24-hour delivery from field-visit completion. Rush options available with surcharges (+$195 / +$295). The PDF arrives by email; we can also route it directly to your insurer, lender, title agent, or any other party you specify.

§ 02 · ABOUT ALUMICONN

About the connector itself.

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. Our 2025 acceptance rate on first submission was 100% across twelve major carriers.

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.

§ 03 · PRICING & SCOPE

What it costs.

Three tiers by home size: Small (under 1,500 sqft) $625 / Medium (1,500–2,500 sqft) $850 / Large (2,500+ sqft) $1,100. Rush surcharges +$195 for 48-hour, +$295 for 24-hour. Multi-property and portfolio discounts available for sellers and investors.

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

No — we don't install. The electrician install is a separate bill from your electrician (or one we refer). Typical electrician labor for an average home runs $400–$900 depending on device count. Total all-in cost for medium home: $1,250–$1,750.

Yes. Portfolio discount of 10% per cert kicks in at 2 properties; 15% per cert at 6+ properties. Common for investors doing renovate-and-resell on pre-1974 stock, or for landlords clearing aluminum across a rental book. We can also coordinate field visits as a batch to compress the timeline.

See For Pre-Listing for portfolio pricing details.

We offer a confirmation visit at $185 to verify whether you actually have aluminum branch wiring and how many devices are affected before you commit to a full remediation. We pull 2–3 representative devices, photograph the conductor, and give you a written finding the same day. If you proceed to certification with us, the confirmation fee credits 100% toward the cert.

§ 04 · SCHEDULING & TIMING

How fast we can move.

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.

§ 05 · INSURERS & LENDERS

Who accepts what.

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.

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.
