Aluminum wiring (homes from roughly 1965-1975) raises safety and insurability concerns. Here is how to recognize it and fix it.
Why aluminum
During the ~1965-1975 period, aluminum often replaced copper for residential wiring.
The real risk
The danger mainly comes from overheating at the connections (outlets, switches, panel), not the wire itself.
The signs
- Warm outlets or switches.
- Breakers that trip.
- A hot-plastic smell.
The recognized fixes
COPALUM or AlumiConn connectors installed by a qualified electrician. Rarely a need to redo everything.
Insurability
Some insurers require an inspection and fixes before insuring.
Frequently asked questions
Does everything need to be redone?
Rarely, fixes at the connections are often enough.
Can insurance refuse?
Some insurers require an inspection or fixes; confirm before buying.
