What Every Homeowner Should Know
If your home was built between 1965 and 1975, there’s a good chance it contains aluminum wiring—and that could be a serious safety hazard. While aluminum was once used as a cheaper alternative to copper, we now know it’s far more prone to overheating, arcing, and even starting electrical fires.
In this blog, we’ll break down why aluminum wiring is risky, how to spot the warning signs, and what certified electricians can do to make your home safer.
Why Aluminum Wiring is a Problem
Aluminum expands and contracts more than copper, which causes connections to loosen over time. It also corrodes faster, creating resistance at connection points that can lead to overheating and fire hazards. In fact, studies show homes with aluminum wiring are 55 times more likely to experience electrical fire conditions.
Signs You Might Have Aluminum Wiring
- Lights flickering or dimming
- Warm or discoloured light switches/outlets
- Buzzing sounds from walls
- Breakers frequently tripping
- Your home was built between 1965 and 1975
If you’re noticing these symptoms, it’s time to have your home inspected by a licensed electrician.
Your Options: Replace or Retrofit
1. Full Replacement
Completely removing and replacing aluminum with copper wiring is the most thorough, safest option—especially for homes with widespread issues.
2. Copper Pigtailing Retrofit
A more cost-effective option, copper pigtailing safely connects aluminum wires to outlets using approved connectors. This method meets BC’s Electrical Safety Regulation.
The Insurance Problem
Many home insurers are either denying coverage or increasing premiums for homes with aluminum wiring unless certified repairs or upgrades have been performed. A certified inspection and documented upgrade can help restore your home’s insurability.
