Why You Need to Replace Aluminum Wiring (In your Calgary Home)

Why You Need to Replace Aluminum Wiring (In your Calgary Home)


Was your Calgary home built between the 1960’s and 70’s? If so, keep reading as it’s possible that you have been outfitted with aluminum wiring and need to replace it immediately. Electricians used aluminum wiring back then because it was more conductive than copper, not to mention cheaper. Not long after, aluminum wiring was found to be an electrical hazard, causing panic among homeowners.

How is Aluminum Wiring Dangerous?

The increased conductivity and cheaper costs aside, aluminum wiring poses numerous threats to your home and your safety.

  • Compared to copper wiring, aluminum wiring is substantially softer, which means it’s more susceptible to being cut, broken or damaged. This could lead to exposed wiring.
  • When aluminum wiring rusts, it’s less conductive than copper wiring. Additionally, it can inhibit the flow of electricity throughout your home.
  • When hot, aluminum wiring expands and contracts. This will result in wires and connections becoming loose.
  • All of these issues can lead to overheating, which could cause an electrical fire.

How is Copper Wiring Better?

While copper wiring is more expensive, you can’t really put a price on the safety of your family. Here are the reasons why electricians switched to copper wiring:

  • Copper wiring is extremely flexible and durable. In fact, it can twist and not break. Its durability ensures that connections are safe and solid.
  • You won’t have to worry about completing maintenance as often.
  • Copper also has a high conductivity rate.
  • You will increase the value of your home by replacing your aluminum wiring with copper wiring.

Signs You Need to Replace Your Wiring

If you’re not sure whether you have aluminum or copper wiring in your home, watch out for these common signs indicating a need for wire replacement:

  • Flickering lights that occur without reason
  • Light switches and/or outlets are warm to the touch
  • When a device or appliance is plugged in, sparks or smoke appear
  • Breakers or fuses are constantly tripping
  • Radios, televisions and computers show static
