REWIRING & ALUMINUM WIRING RESTORATION FAQ’S
If you have any questions about aluminum wiring or rewiring services, please give our friendly specialists a call. Here are some common questions our customers ask.
HOW CAN I TELL IF MY HOME HAS ALUMINUM WIRING?
The first thing to note is that aluminum wiring was only used as a standard home wiring material in the late 1960s and 1970s. So if your home was built before or after that date, it’s unlikely you have aluminum wiring.
If you’re unsure of the age of your home, aluminum wiring can be identified by its colour. Aluminum is silver in hue, while copper is a yellow or rust colour. You can also look for a label on the wire jacket (outside layer). It will be marked as “AL” or “aluminum.”
Our electricians can always assess your home’s electrical and let you know what materials are used for your home’s wiring.
WHAT ARE THE PROBLEMS WITH ALUMINUM WIRING?
Quite simply, aluminum wiring is inferior to copper as an electrical conductor. It was used to save costs in past eras, but there are challenges when using aluminum for home wiring.
Aluminum is sensitive to temperature changes and expands and contracts. The compression quality of aluminum wiring is high, so wires can easily bend and distort. Aluminum wiring is also sensitive to moisture (corrosion) and oxygen (oxidization).
All of these problems can lead to aluminum wiring losing its conductivity and becoming a fire threat. Rewiring with copper is one way to eliminate the shortcomings of outdated aluminum wiring.
I HAVE ALUMINUM WIRING. WILL I NEED TO REWIRE MY WHOLE HOUSE?
Not always. Although aluminum wiring has many safety concerns, you do not necessarily need to rewire your entire home. When properly installed, aluminum wiring is safe. But the lifetime of aluminum as a wiring material is limited to about 80 years.
Homes built in the 1960s or 70s with original aluminum wiring should have their electrical systems inspected regularly by a certified electrician. Wiring that is distorted or corroded should be replaced immediately.
It’s often only necessary to restore the section of wiring that is failing. Many home insurance providers require certain electrical restorations when you purchase a new property. Our electricians will assess your current wiring and help you make a decision about how much aluminum wiring should be restored.
HOW MUCH DOES REWIRING MY HOME COST?
In simple terms, the cost of rewiring an entire home is based on the total length of wire being replaced and the number of outlets your home has. Larger homes are more expensive to rewire.
Unless your outlets are rated for both copper and aluminum wiring, they will also need to be replaced to be compatible with your new wiring. Aluminum wiring should not be connected to copper except with the help of an electrical expert.
Restoring certain sections of your home’s wiring is more affordable than a complete rewiring service. Costs will vary depending on the exact requirements of the aluminum wiring restoration.

What To Expect With aluminum wiring replacement
1. Evaluation
Your personal, licensed electrician will conduct a thorough inspection of your home to identify areas wired with aluminum wiring. They will also take notes on the age and condition of the wiring, looking for signs of deterioration or improper connections.
The electrician will then assess the potential risks associated with your wiring.
2. Recommendation
Based on the evaluation, your electrician will recommend restoring the aluminum wiring with copper tails and proper connections or possibly replacing the aluminum wiring with copper wiring in open areas.
A detailed cost and timeline estimate will be provided to help you better prepare for installation.
3. Replacement
Once your quote is approved, your electrician can get right to work. They will begin by turning off power to the affected circuits and ensuring safety protocols are in place. Your electrician will need to gain access to your electrical outlets to restore or replace the wiring depending on the option.
The aluminum wiring is carefully restored or removed and replaced with copper, and your electrician will ensure that all connections are properly secured and to code.
They will then replace outlets and switches to ensure compatibility with your new wiring.
Once the restoration or replacement is complete your electrician will do a complete inspection to ensure quality workmanship.
