How much does it cost to upgrade aluminum wiring?

Aluminum wiring upgrades in Ottawa typically cost $150-$300 per outlet/switch, or $3,000-$8,000 for a whole-home remediation, depending on your home's size and the chosen repair method.

Aluminum wiring was commonly installed in Ottawa homes between 1965-1975 and poses serious fire risks due to its expansion/contraction properties and incompatibility with standard copper-rated devices. Many insurance companies now require remediation or charge higher premiums for homes with aluminum wiring.

There are three main approaches to aluminum wiring repair:

Pigtailing is the most common and cost-effective method, where short copper wire segments are connected to aluminum wires using special COPALUM or AlumiConn connectors. This typically runs $150-$300 per connection point, so a typical Ottawa home with 30-40 outlets and switches would cost $4,500-$12,000. The work requires an ESA-licensed electrician and permit.

Complete rewiring involves replacing all aluminum wiring with copper throughout the home. For a typical 1,500 square foot Ottawa home, this ranges from $8,000-$15,000 including permits and ESA inspection. While more expensive upfront, it's the permanent solution and often required for insurance coverage.

Panel and circuit upgrades may also be needed, as many homes with aluminum wiring have older 100-amp panels. A combined aluminum wiring remediation and panel upgrade typically costs $6,000-$12,000.

ESA permits are required for aluminum wiring work in Ontario, and the repair must be completed by a licensed electrician. Insurance companies often require an ESA Certificate of Inspection showing the work was completed to code before they'll provide coverage.

Safety is critical - aluminum wiring connections can overheat and cause fires, especially at outlets, switches, and junction boxes. Signs of problems include warm cover plates, flickering lights, or burning smells. If you notice these symptoms, have the wiring inspected immediately.

The investment in aluminum wiring remediation typically pays for itself through lower insurance premiums and increased home value, while eliminating a serious fire hazard.
