The Truth About Aluminum Wiring and When to Call a Residential Electrician in Ottawa

If your home was built in the 1960s or 70s, there’s a good chance it contains aluminum wiring. At the time, it was considered a cost-effective alternative to copper, but decades later, it’s become a common cause of electrical concerns in older homes. Understanding the risks and knowing when to call a residential electrician in Ottawa can help you prevent serious problems down the road.

Companies like Eric Lalonde Electrical Services Inc. have been helping homeowners across Ottawa inspect, repair, and upgrade aluminum wiring safely and efficiently.

Why aluminum wiring can be risky

Aluminum conducts electricity well, but it expands and contracts more than copper when it heats up. Over time, this movement can loosen connections, creating resistance and, in some cases, heat buildup. The result? Flickering lights, warm outlets, or even potential fire hazards.

A qualified residential electrician in Ottawa can identify these weak points before they become dangerous. Eric Lalonde Electrical Services Inc. often finds that minor issues—like loose connections or corrosion—can be resolved through proper maintenance rather than a full rewiring job.

How to know if your home has aluminum wiring

Many homeowners don’t realize they have aluminum wiring until an inspection or renovation reveals it. If your house is very old, there’s a good chance it’s wired with aluminum. You can sometimes identify it by looking at exposed wiring where it connects to outlets or the electrical panel—the marking “AL” or “ALUM” is a clear sign.

That said, it’s safer to let a residential electrician in Ottawa confirm the wiring type. Eric Lalonde Electrical Services Inc. performs detailed inspections using specialized tools to evaluate connections and ensure your system meets current safety codes.

Repair or replace: what’s the right move?

Not every home with aluminum wiring needs a full replacement. In many cases, Eric Lalonde Electrical Services Inc. recommends a method called “pigtailing,” where short pieces of copper wire are connected to the ends of the aluminum wiring using approved connectors. This reduces the risk of overheating while maintaining the existing electrical system.

However, if your home shows widespread signs of corrosion, overheating, or repeated tripping circuits, a full rewiring may be the safest option. During an Ottawa electrical renovation, replacing aluminum wiring with copper not only improves safety but can also increase your home’s resale value.

Why routine inspections matter

Even if your wiring seems fine, regular inspections are essential. Ottawa’s seasonal temperature swings—from humid summers to freezing winters—put extra stress on electrical systems. Scheduling an inspection with Eric Lalonde Electrical Services Inc. ensures that your connections remain tight, your outlets operate safely, and your home’s wiring complies with the Ontario Electrical Code.

Preventive maintenance costs far less than emergency repairs and gives you peace of mind that your system is safe and efficient.

If you suspect your home has aluminum wiring or notice flickering lights, warm switches, or tripping breakers, contact Eric Lalonde Electrical Services Inc. Their licensed team can inspect, repair, or rewire your system safely and help you make informed decisions about your home’s electrical health.
