What is aluminum wiring and is it dangerous in older Bloomington homes?

Quick answer: Aluminum branch-circuit wiring was used in many homes built in the mid 1960s through the 1970s, a period that covers a portion of Bloomington's housing stock. Aluminum expands, contracts, and oxidizes more than copper, which can loosen connections at outlets and switches and create heat that raises fire risk. It is not automatically unsafe, but it requires proper, approved connections. An inspector flags suspected aluminum wiring and recommends evaluation by a licensed electrician.

The concern is at the connection points, not the wire running through the walls. Loose or corroded terminations at receptacles, switches, and the panel generate heat over time. This is why aluminum wiring deserves professional attention even when nothing seems wrong today.

Accepted remediation methods include approved connectors that pigtail copper onto the aluminum at each device, or other manufacturer-approved repairs performed by a licensed electrician. Simply replacing devices with aluminum-rated terminals is also part of some solutions.

If your inspection suggests aluminum wiring, have an electrician assess the whole system before closing. Insurance carriers sometimes ask about aluminum wiring, so documented, professionally completed remediation can matter for coverage as well as safety.
