The Dangers of Old Aluminum Wiring


Is your house 40 years old or older? Have you replaced any major appliances in the last 10 years? Did somebody own your home before you moved in? If you answered “yes” to any of these scenarios, your home could be at risk! Of what? Of old aluminum wiring that has the ability to wreak havoc.


Although copper wiring is the preferred metal to use when it comes to electrical wiring, older homes (those built in the 60s and 70s) were likely constructed using aluminum wiring. During this time period, the price of copper increased dramatically making aluminum a much more affordable option.

Why is Aluminum Wiring Dangerous?

  • Most outlets and receptacles were not intended to be compatible with aluminum.
  • Shoddy installation practices often result in loose or deteriorating connections.
  • Aluminum wiring is more likely to pose a potential fire hazard.

According to the CPSC, an estimated 2 million homes built or remodeled between the late 1960s and mid-1970s contain aluminum wiring. And if you plan on getting your home insured, it’s important to note that many insurance companies will not provide you with coverage unless your home’s electrical wiring is upgraded from the hazardous aluminum material.

If you know that your house was built or renovated during this time period, take a look at your wiring. You may notice the letters “Al” on the outer jacket of electrical cables which means that they are in fact aluminum wires.
