Aluminum Wiring Replacement
Aluminum wiring repair and replacement to reduce fire risk and meet insurance requirements.

Overview
Aluminum branch wiring was common in homes built or renovated through the 1960s and 70s, and the risk isn’t the metal itself, it’s what happens at the connections. Aluminum expands and contracts more than copper and oxidizes at the terminal, which loosens connections over time and can lead to overheating at outlets, switches, and the panel. We assess every aluminum connection in your home and remediate it, either with a full copper rewire or with approved connection methods, so the risk is actually resolved, not just hidden behind a new cover plate.
- Full rewire or approved-connector remediation
- Insurance-ready ESA documentation
- Every aluminum connection checked, not just the panel

Why It Matters
The failure point with aluminum wiring is almost always the connection, not the wire itself, which is why outlets and switch plates that feel warm, show discolouration, or spark when a plug is inserted are the clearest warning signs. Insurers frequently flag aluminum wiring during a policy review or a home sale, and some require it to be remediated by a licensed electrician before coverage is issued or renewed. There are two accepted approaches: a full copper rewire, which eliminates the aluminum entirely, or remediation using approved connectors such as COPALUM crimps or AlumiConn connectors at every affected junction. We’ll walk you through which option fits your home and budget rather than defaulting to the most expensive one.
How Aluminum Wiring Replacement Works
- 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
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
Remediation work
We rewire the affected circuits or install approved connectors at every aluminum-to-copper junction, following manufacturer and code specifications.
- 4
ESA inspection & documentation
You receive a certificate of inspection confirming the work meets code, which most insurers will accept as proof of remediation.
What Affects the Cost
Cost depends on whether you choose a full rewire or connector-based remediation, how many circuits and connections are affected, and how accessible your outlets, switches, and panel are.

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.
