A copper scarcity within the ‘60s caused many properties to be electrically wired with aluminum.
Sometimes aluminum rewiring is changed by tearing out partitions. After the rewiring is full, you have to set up new drywall. Replacing aluminum wiring can cost more than $10,000 to switch.

Aluminum has a better rate of growth than copper wiring, which might result in free connections, arcing and melting, finally fireplace. Warm cowl plates or discolouration of switches or receptacles, flickering lights or the odor of sizzling plastic insulation could also be proof of poor or improperly made connections.
Loose connections enhance electrical resistance, which may melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds must be used.
