In addition to this, double check there isn't aluminum wiring mixed with other non-aluminum stuff; the thermal expansion is different between Al and other metals Cu/Brass, etc, causing joints to weaken over time. Once loose they arc routinely with any vibrations in the house, getting looser and looser with time, eventually becoming a fire hazard.

I just had to address this in my place. Expensive mess but I’ll sleep better now. If anyone is wondering I opted to use the AlumiConn connectors. Best I could do without opening up more walls and ceilings.

Every time I open up a fixture or outlet in my house I remediate the mixed-metal wiring with AlumiConn connectors. They're kind of expensive and a hassle to get crammed back into the box, but it's a hell of a lot better than spending $??,000 to rewire the whole house, and it's supposedly a permanent remediation method.

Not a shill, just a guy who bought a house from an idiot.

Lol. Must have been the same idiot I bought from. I do know that I no longer have any aluminum in outlet, switch, or light junction boxes. We rewired the bulk of the house when we purchased it. Which leads me to believe the aluminum wiring I found in a wall I was demoing recently is connected to copper in the attic (I contracted out the attic and main panel work). Guess I need to get up there with another box of these connectors.
