Aluminum Electrical Rewiring FAQs

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 permitted as a 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.

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 Rewiring with copper is one way to eliminate the shortcomings of outdated aluminum wiring.

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. The safest course of action is to rewire your entire home.

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.

All of these factors affect the price of home rewiring services.
