A copper shortage within the ‘60s brought on many properties to be electrically wired with aluminum.
Sometimes aluminum rewiring is replaced by tearing out partitions. After the rewiring is complete, you must install new drywall. Replacing aluminum wiring can cost more than $10,000 to switch.

Warm cover plates or discolouration of switches or receptacles, flickering lights or the scent of hot plastic insulation may 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 ought to be used.
