The History

In 1965 home builders were facing a new challenge. There was a shortage of copper throughout the US. Between decades of military usage, new coins using copper (instead of silver), and the advantages of aluminum; home builders were not using copper in the wiring of their homes. Homes built between 1965 and the early 1970s, were wired primarily using aluminum wiring. 

Aluminum Wiring Benefits

Aluminum wiring was lighter than that of the copper wiring. This and the scarcity of copper are what lead to it being used. That is it.

Aluminum Wiring Problems

Aluminum is not able to conduct electricity as efficiently nor as safely as copper. Aluminum’s conductivity, when compared to copper, is only 61%. In addition to the lesser conductivity, aluminum is 55% more likely to become a fire hazard. Aluminum wiring can overheat and produce sparks, which become a fire hazard. Finally, aluminum wiring can become dangerous when it rusts. When aluminum wiring rusts, it loses the ability to conduct electricity and can cause overheating. 

Impact on Homeowner’s Insurance

Many insurance companies will not insure a home with aluminum wiring. If you are buying or selling a home for cash, this may not be an immediate concern. However; if the buyer is securing a mortgage, the mortgage company will more than likely not grant funts without the homeowner’s insurance. 


Rewiring a home can range from $3,500-$8,000 for a 1,200sqft home to $15,000+ for a 3,000sqft home. The truth is, it will be expensive. What is great though is that the selling process is a negotiation. As a seller, I could increase my equity in the home by rewiring it and then putting it on the market with a markup for the new wiring. As a buyer, I could get the owner to replace the wiring and split the cost by raising the sales price proportionately. There are an infinite number of other possibilities when it comes to how to tackle the re-wiring of the home but these may be the two simplest methods.
