How much does it cost to replace aluminum wiring in Ottawa?

Aluminum wiring replacement in Ottawa typically costs $150-$300 per outlet/switch, or $3,000-$8,000 for a whole-home rewire, depending on your home's size and the extent of aluminum wiring present.

Most Ottawa homes built between 1965-1975 have aluminum branch circuit wiring, which creates fire and safety risks due to aluminum's expansion properties and connection issues. The Ontario Electrical Safety Code now prohibits new aluminum wiring installations for branch circuits (though it's still allowed for service entrance cables).

Replacement options and costs in Ottawa:

For partial aluminum wiring (common in split-level homes where only some circuits are aluminum), you're looking at $150-$300 per outlet or switch replacement. This includes running new copper wire from the panel to each device, which requires ESA permits and inspection. A typical room with 4 outlets and 2 switches would cost $900-$1,800 to rewire.

For extensive aluminum wiring throughout the home, a whole-home rewire is often more cost-effective. In Ottawa, expect $3,000-$8,000 for a complete aluminum-to-copper conversion in an average 1,200-1,500 sq ft home. Larger homes (2,000+ sq ft) can reach $10,000-$15,000. This includes new copper wiring, updated outlets and switches, ESA permits, and inspection.

Insurance considerations make this work urgent for many Ottawa homeowners. Most insurance companies either refuse coverage or charge significantly higher premiums for homes with aluminum wiring. Some insurers require immediate remediation or policy cancellation. Getting quotes from multiple insurers after aluminum wiring replacement often results in substantial premium savings that help offset the rewiring costs.

ESA permit requirements apply to all aluminum wiring replacement work. Your licensed electrician must pull permits before starting, and ESA inspection is mandatory. The good news is that once completed and inspected, you'll have documentation proving your electrical system meets current safety standards.

Safety warning: Never attempt DIY aluminum wiring work. Aluminum connections require special techniques and materials (like CO/ALR rated devices). Improper connections create fire hazards that have caused numerous house fires across Ottawa.
