Why Aluminum Wiring Was Used
During the late 1960s copper prices spiked, and builders switched to aluminum wiring for branch circuits. It was approved by code and widely used — but it behaves differently than copper and requires specific handling at connections.
The Safety Concern
Aluminum expands and contracts more than copper with temperature changes. Over time, this loosens connections at outlets, switches, and fixtures — creating resistance, heat, and potential fire hazard. The Consumer Product Safety Commission found aluminum-wired homes had significantly higher fire risk.
“Infinite Electric assessed our aluminum wiring thoroughly and explained our options clearly. We went with CO/ALR devices throughout and feel much safer. — Duane H., Manassas VA”
How to Address It
The two main approaches are: replacing all branch circuit wiring with copper (the most thorough solution), or retrofitting all connection points with CO/ALR-rated devices and anti-oxidant compound (a code-compliant remediation). We assess your specific situation and recommend based on age, condition, and your goals.
Insurance Implications
Some Northern Virginia homeowners find their insurance premiums are higher for aluminum-wired homes, or certain policies require documentation of proper remediation. A written inspection report from a licensed electrician documents the condition for your insurer.
