Will Your Insurance Drop You for Aluminum Wiring?

Why Insurers Care About Aluminum Wiring

Insurance companies base coverage decisions on risk, and aluminum wiring at connection points carries a documented fire risk. The Consumer Product Safety Commission found that homes with aluminum wiring are significantly more likely to have fire conditions at connection points than homes with copper wiring. This finding drives insurer caution.

The risk is not the aluminum wire itself running through the walls. The risk is at every outlet, switch, and junction box where the aluminum connects to a device. Aluminum expands and contracts more than copper under load, loosening connections over time. A loose connection generates heat, and that heat can ignite surrounding materials.

What Triggers the Insurance Question

New Policy Application

When you apply for homeowner’s insurance, the insurer may ask about the age of the home and the type of wiring. If the home was built between 1965 and 1973, the insurer may require an inspection to determine whether aluminum wiring is present. If it is, the insurer may require remediation before issuing the policy.

Policy Renewal Review

Some insurers conduct periodic reviews of their book of business and flag homes in the aluminum-wiring-era build range. If your home is flagged, you may receive a letter requiring proof of remediation within a set timeframe, typically 60 to 90 days. If you do not provide proof, the insurer may non-renew the policy.

Claim Inspection

If you file a claim for any reason and the adjuster discovers aluminum wiring during the inspection, it can trigger a remediation requirement as a condition of continued coverage. This is an awkward time to discover the issue because you are already dealing with whatever caused the claim.

Home Sale

The buyer’s insurer often discovers aluminum wiring during the underwriting process for a new policy. If the insurer requires remediation before coverage, the buyer may ask the seller to pay for it, or the sale may stall until the issue is resolved.

What Remediation Involves

The AlumiConn Method

The standard remediation accepted by most insurers is the AlumiConn connector method. An electrician opens every outlet, switch, and junction box in the house, inspects the aluminum connections, and installs AlumiConn connectors at each point. The connector creates a mechanical bond between the aluminum wire and a short copper pigtail, and the copper pigtail connects to the device.

On a typical three-bedroom home, this involves 40 to 60 connection points and takes a full working day. The electrician replaces any devices that show signs of overheating damage during the process.

The Completion Letter

After remediation, the electrician provides a completion letter on company letterhead that documents:

• The property address
• The date of remediation
• The number of connection points inspected and remediated
• The method used (AlumiConn or equivalent approved connector)
• Any devices replaced due to damage
• The electrician’s licence information and contact details

This letter is the document the insurer needs. Keep the original with your insurance papers.

Full Replacement

Some homeowners choose to replace the aluminum wiring entirely with copper. This is a full or partial rewire and costs significantly more than connection remediation. It is not required by most insurers if AlumiConn remediation is performed, but some homeowners prefer the peace of mind of copper throughout.

Cost of Remediation vs. Coverage Loss

Aluminum wiring remediation on a three-bedroom home is a fraction of the cost of losing coverage. Losing insurance and finding a new policy on a home with known aluminum wiring is difficult and expensive. The remediation cost is almost always less than the premium increase or the difficulty of finding alternative coverage.

Proactive vs. Reactive

If your home was built between 1965 and 1973, check for aluminum wiring before your insurer asks. Proactive remediation gives you the completion letter before the question comes up, avoids the pressure of a deadline, and puts you in a stronger position at renewal time. Reactive remediation under an insurer’s 60-day deadline is the same work at the same cost, but with less scheduling flexibility.
