Aluminum Wiring in Calgary Homes: Risks and the Simple Solution of Pigtailing

Calgary’s housing boom in the 1960s and 1970s brought with it a wave of innovation - and a few shortcuts. One of those shortcuts was the widespread use of aluminum wiring. While it helped keep construction costs down during a time when copper was pricey, aluminum wiring has since gained a reputation for being a potential fire hazard. But here’s the good news: there’s a straightforward fix that can put your mind at ease.

What’s the Issue with Aluminum Wiring?

Aluminum is a great conductor, but it behaves differently from copper. Over time, aluminum wiring can oxidize, expand, and contract more than copper, which can lead to loose connections, overheating, and even electrical fires. Insurance companies and home inspectors in Calgary often flag aluminum wiring as a concern, especially in homes built between the mid-1960s and late 1970s.

How to Spot Aluminum Wiring

• Check your electrical panel or outlets for wires labeled “AL” or “Aluminum.”
• Homes built between 1965 and 1978 are the most likely to have aluminum wiring.
• If you’re unsure, a licensed electrician can easily confirm what’s behind your walls.

Pigtailing: The Simple, Effective Fix

If you discover aluminum wiring in your Calgary home, don’t panic - you don’t have to rewire the entire house! The most common solution is called “pigtailing.” This involves connecting short lengths of copper wire to the ends of the existing aluminum wires using special connectors approved for this purpose. These copper “pigtails” are then attached to outlets, switches, and fixtures, reducing the risk of overheating and fire.

• Quick and Cost-Effective: Pigtailing is much less invasive and expensive than full rewiring.
• Insurance-Friendly: Many insurance companies accept pigtailing as a safe upgrade, helping you secure coverage and peace of mind.
• Professional Installation Required: Always hire a licensed electrician with experience in aluminum wiring remediation to ensure the job is done safely and up to code.

Final Thoughts

Finding aluminum wiring in your Calgary home can be unsettling, but with the right fix, it doesn’t have to be a dealbreaker. Pigtailing offers a reliable, affordable solution that keeps your home safe and insurable. If you have questions or want to know more about your options, reach out to a trusted local electrician - they’ll help you keep your home’s electrical system running smoothly for years to come.
