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

Aluminum has a higher rate of growth than copper wiring, which might result in loose connections, arcing and melting, eventually hearth. Warm cover plates or discolouration of switches or receptacles, flickering lights or the scent of scorching plastic insulation could additionally be evidence of poor or improperly made connections.
Loose connections enhance electrical resistance, which might melt fixtures and insulation. Approved copper-to-aluminum connections plus antioxidant compounds ought to be used.
