What is aluminum wiring and is it dangerous?
Aluminum branch circuit wiring installed in homes built between 1965–1973 is a fire hazard. Aluminum expands and contracts differently than copper, loosening connections and creating heat buildup.

A professional inspection identifies aluminum wiring and assesses fire risk. Address this immediately—aluminum wiring increases insurance claims. ProvenQuote connects you with electricians certified to safely upgrade your system.
