If your home or condo was built in the late 1960s or early 1970s, you may have heard the phrase “aluminum wiring” said with a raised eyebrow. Here’s the calm, practical truth: What it is: Some homes (especially built or renovated roughly 1965–mid 1970s ) used solid aluminum “branch circuit” wiring for everyday outlets and lighting. Why it gets attention: Aluminum behaves differently than copper at connection points (outlets, switches, fixtures), which can increase the risk of overheating if the system hasn’t been properly remediated. What to do first: Don’t guess. Have a qualified electrician confirm what you have and assess the connections. Why it matters for insurance: Some insurers ask about aluminum wiring—and what matters most is what remediation was done and how it’s documented . This guide explains what aluminum wiring is, why it can be a concern, what “fixing it” actually means, and how to think about the insurance side without panic. What counts as “aluminum wiring” (and what doesn’t) When people say “aluminum wiring,” they usually mean solid aluminum branch-circuit wiring used for 15- and 20-amp circuits that feed outlets, lights, and switches . Two important clarifiers: Not all aluminum in a home is the same risk. Many homes have aluminum in other contexts (for example, certain larger circuits or utility connections) that are not the same issue being discussed here. A home inspection note isn’t the final word. It’s common for reports to flag “possible aluminum wiring” and recommend further evaluation. If you’re unsure, the right move is simple: ask an electrician to identify the conductor type and where it’s used . Why aluminum wiring can be a real concern Aluminum was widely used during a period when copper was more expensive and harder to source. The issue isn’t that aluminum “can’t” conduct electricity—it can. The issue is what can happen over time at connections . The U.S.
