Aluminum Wiring Inspection & Remediation in Calgary

Aluminum wiring isn't inherently dangerous, but it expands and contracts more than copper. Over decades, this loosens connections, creates heat buildup, and increases fire risk. Homes with aluminum wiring are statistically more likely to have fire hazards at connection points, which is why inspection and remediation are strongly recommended.

Some Calgary insurance companies will cancel or refuse to renew policies on homes with unremediated aluminum wiring. Others increase premiums significantly. Having a licensed electrician complete a proper pigtailing or replacement with a certificate of compliance typically satisfies their requirements.

Pigtailing connects a short piece of copper wire to each aluminum wire connection point using approved connectors like AlumiConn or Marrette 65s. This creates a safe copper-to-device connection at every outlet, switch, and fixture. It's the most common and cost-effective remediation method accepted by insurance companies.

In most cases, pigtailing is the recommended approach. It's approved by the Alberta Electrical Code, accepted by insurance companies, and far less invasive than a full rewire. Full replacement may make sense during a major renovation where walls are already open. We can assess your home and recommend the best option.
