Aluminum Wiring Replacement

Making 1960s–70s aluminum branch wiring safe with copper or approved remediation.

The Aluminum Wiring Problem

Blue Moon Electrical’s aluminum wiring replacement addresses the actual fire risk aluminum branch circuits create as connections loosen over time. Many homes built in the 1960s and 1970s used aluminum for branch circuits. Aluminum expands, contracts, and oxidizes more than copper, so over the years its connections at outlets, switches, and the panel loosen and overheat. The wire inside the walls is rarely the danger; the terminations are. That’s why the fix targets every connection point, and why a careful assessment matters before deciding how far the work needs to go.

The Aluminum Wiring Problem

The federal Consumer Product Safety Commission has studied this exact problem and found that homes wired with aluminum branch circuits are far more likely to have a connection reach dangerous, fire level temperatures than homes wired with copper.

A licensed electrician has to check every connection point, not just the wire itself. It is the screw terminal at an outlet, switch, or breaker where the aluminum has loosened over time that creates the heat.

Signs of Aluminum Wiring

You may have aluminum branch wiring if your home dates to roughly 1965 through 1975, if the cable markings read aluminum or AL, or if you notice warm cover plates, flickering, or a faint burning smell at outlets and switches. A home inspection or an electrician can confirm it quickly. Because the real risk lives at the connections, symptoms tend to appear there first, which is exactly where any genuine remedy has to focus.

Outlets that have failed or scorched

Identifying Aluminum Wiring at the Panel

You can often get a first clue right at your electrical panel. Aluminum conductors typically look dull silver rather than the reddish orange of copper, and the metal itself is noticeably softer and easier to nick.

Some panels and older permit records even list the wire type on a sticker or inspection tag. The only reliable way to confirm what you have is to have a licensed electrician open the panel and check.

How It's Made Safe

Two remedies are recognized as effective. The thorough option pulls out the aluminum branch circuits and runs copper in their place, which is the most permanent answer and ideal whenever the walls are already open. Where pulling new cable isn’t practical, an approved method bonds a short copper pigtail onto each aluminum conductor with listed connectors, so every termination ends on copper. After studying the connections, the electrician recommends whichever approach suits the home and the budget. Every aluminum wiring replacement is completed to current code, with permits and inspection included.

CPSC-Recognized Repair Methods

When Blue Moon Electrical recommends remediation instead of full replacement, it means installing one of two connector systems the CPSC recognizes as effective fixes.

The first is the COPALUM crimp connector, which uses a specialized tool to permanently fuse a copper pigtail onto the aluminum wire under very high pressure.

The second is the AlumiConn connector, a setscrew style pigtail accepted by most insurers. Either method has to be installed by a trained electrician.

What Affects the Cost

Aluminum wiring replacement does not have one set price because every home’s scope is different. The number of devices involved, whether remediation or full replacement fits better, and how accessible the walls and panel are can all change the total.
Blue Moon Electrical provides a free on-site assessment first, then gives a firm written quote for the recommended approach before any work begins.

Replace or Remediate?

Full replacement is the gold standard and makes the most sense during a remodel or when walls are already open. Approved remediation — copper pigtails with listed connectors at every device — is a recognized, effective fix when replacement isn’t practical, and it satisfies most insurers. The right choice depends on your home, your plans, and what your insurer requires, which is why we lay out both before you decide.

Aluminum Wiring Replacement FAQs

Common questions about aluminum wiring replacement, remediation, and cost.

Q. Is aluminum wiring dangerous?

The wire itself isn’t the main hazard; its connections are. Aluminum loosens and oxidizes over time, and loose connections overheat, which raises fire risk. Treating every connection — by replacement or approved remediation — removes the danger.
Pigtailing joins a short copper wire to the aluminum at each device using listed connectors, so the device terminates on copper. Done with approved connectors at every connection, it’s a recognized, effective remediation accepted by most insurers.
Many insurers ask that aluminum branch wiring be replaced or properly remediated to issue or keep coverage. Requirements vary, so it’s worth confirming what yours accepts; both accepted fixes are designed to satisfy that concern.
