Aluminum Wiring Replacement in Mississauga

How Aluminum Wiring Replacement Works

1. 1

   Inspection & risk assessment

   We check every outlet, switch, and panel connection on aluminum branch circuits for signs of oxidation, loosening, or heat damage.

2. 2

   Remediation plan

   We recommend a full rewire or approved-connector remediation based on the extent of the aluminum wiring and your budget, and explain the tradeoffs of each.

3. 3

   Remediation work

   We rewire the affected circuits or install approved connectors at every aluminum-to-copper junction, following manufacturer and code specifications.

4. 4

   ESA inspection & documentation

   You receive a certificate of inspection confirming the work meets code, which most insurers will accept as proof of remediation.

Frequently Asked Questions

Is aluminum wiring actually dangerous?

The wire itself isn’t inherently dangerous, but its connections loosen over time due to oxidation and expansion, which can lead to overheating. That’s why remediation focuses on every connection point, not just the wire.

What’s the difference between a rewire and connector remediation?

A full rewire replaces the aluminum wiring with copper entirely. Connector remediation uses approved connectors, like COPALUM or AlumiConn, at each junction to safely join aluminum wire to copper pigtails without replacing the whole run.

Will my insurance company accept connector remediation instead of a full rewire?

Most Ontario insurers accept properly documented connector remediation using approved connectors and an ESA certificate. We’ll provide documentation either way, but confirm with your insurer if you’re unsure.

How do I know if my home has aluminum wiring?

Homes built or renovated between the mid-1960s and mid-1970s are the most common candidates. Aluminum wiring is dull grey rather than copper-coloured, and it’s often marked on the cable jacket, but a proper inspection is the reliable way to confirm it.

Do I need to replace all the aluminum wiring at once?

Not necessarily. We can prioritize the circuits or connections showing the most wear first, though a full remediation plan is worth having so nothing gets missed.

How much does aluminum wiring remediation cost?

Cost depends on whether you choose a full rewire or connector remediation, and how many circuits and connections need work. We provide a clear quote after inspecting your home’s wiring.
