Aluminum branch wiring was installed widely in homes built between 1965 and 1972, when copper prices spiked and aluminum was offered as a lower-cost alternative. The problem is not the aluminum wire itself — it is the connection points. Aluminum expands and contracts at a different rate than steel and brass terminals. Over time, this creates loose connections that arc and overheat, and aluminum oxidizes at connection points in ways copper does not. Our licensed electricians assess aluminum wiring systems, recommend the appropriate remediation — pigtailing or full replacement — and complete the work to current NEC and California code standards.
Aluminum Wiring Replacement — Everything You Need to Know
From fire risk to approved replacement methods — here’s what homeowners need to know about aluminum wiring replacement before requesting service.
Pigtailing vs. Full Replacement
Two remediation approaches exist for aluminum branch wiring. Pigtailing uses CO/ALR connectors to join a short copper tail to each aluminum wire at connection points so the final connection to the device is copper rather than aluminum — an accepted remediation recognized by the Consumer Product Safety Commission. Full replacement pulls the aluminum wire entirely and replaces it with copper, eliminating the aluminum condition permanently. We assess each property and recommend the approach that balances safety, durability, and scope.
How to Identify Aluminum Wiring
The AL marking printed on the outer cable jacket visible in attics, basements, and crawl spaces is the easiest identification. Single-strand silver-colored conductors rather than copper-yellow are also a clear indicator. Homes built between 1965 and 1973 are the primary risk window. Warm or discolored outlet and switch plates, flickering lights on circuits that appear functional, and outlets warm to the touch are symptoms of active aluminum connection issues requiring immediate attention.

★★★★★
“Full rewire of our 1952 home — knob-and-tube throughout. Four days of work, very tidy, minimal wall damage. The inspector passed it on the first visit and didn’t find a single issue.”
