Homes built in the 1960s and 1970s were commonly wired with aluminum electrical wiring instead of copper. This shift happened due to a copper shortage during the Vietnam War. While aluminum wiring was considered an acceptable alternative at the time, we now know it can create significant fire and safety risks— especially at connection points throughout the home.
If your home contains aluminum wiring, having it inspected or replaced by a licensed electrician is one of the most important steps you can take to protect your property and your family.
Research shows that homes with aluminum wiring are over 50% more likely to experience electrical fire hazards compared to homes wired with copper. The wiring inside your walls isn’t the issue— the danger lies at the connection points, such as:
Aluminum expands and contracts more than copper when heated. Over time, this movement can loosen connections, leading to overheating and potential fire hazards.
Aluminum oxidizes quickly, reducing conductivity and increasing resistance—another factor that causes overheating.
Aluminum becomes brittle when bent repeatedly, making it more prone to breakage during installation or maintenance.
Aluminum alloy wire performs well in power transmission but is not ideal for residential branch circuits where numerous connection points exist.
If your home has aluminum wiring, watch for these warning signs:
Any of these symptoms should be treated seriously. A licensed electrician should inspect your wiring immediately to prevent electrical shock or fire hazards.
If your home contains aluminum wiring, it’s important to have it inspected by a qualified electrical professional. Aluminum wiring was used in thousands of Calgary homes, and many homeowners are unaware of the risks it poses.
An inspection will help determine:
Protect your home, your family, and your investment by ensuring your wiring is up to date.
Aluminum wiring wasn’t limited to residential construction — it was also widely used in commercial buildings during the same period. If your office, warehouse, or commercial property was built or repaired during the aluminum-wiring era, it’s important to schedule an inspection.
ElectricMan provides:
A proactive inspection can prevent costly downtime, equipment damage, and fire hazards.
If aluminum wiring is causing issues—or if you want to proactively improve safety—there are two main solutions:
The most comprehensive and safest option. This involves removing aluminum wiring and replacing it with modern copper wiring throughout the home.
A cost-effective alternative where certified connectors are installed between aluminum wiring and devices/outlets. This reduces risk at connection points without replacing the entire system.
Both solutions must be performed by a certified electrician trained in aluminum wiring remediation. DIY attempts can worsen the hazard and void insurance coverage.
Aluminum wiring isn’t something to ignore. Whether you’re experiencing issues or simply want peace of mind, having your wiring evaluated by an expert electrician ensures your home remains safe, reliable, and up to code.
