All You Need to Know About Aluminum Wiring


Aluminum wiring was widely installed in homes across America from the mid-1960s through the late 1970s due to its lower costs than copper and perceived effectiveness at performing its task. Over time, however, people realized aluminum wires might not be as safe as once thought. Therefore, if you reside in or plan to buy an older home, you must understand its history and any potential safety concerns associated with its usage. Mr. Electric explores these concerns and when you should contact an electrician in Castle Pines.

Why Did Aluminum Wiring Exist?

Between 1960 and 1974, as copper prices skyrocketed rapidly, builders searched for a cheaper alternative. Aluminum became popular because its cost is less and availability is relatively easy—plus, compared to copper, it's lighter and more flexible, making for easier wiring use overall.

Potential Issues with Aluminum Wiring

Heat and Expansion

Aluminum expands with heat while contracting more dramatically when cool than copper does, leading to loose connections. These might seem minor at first but pose significant fire risks when wires don't remain connected tightly enough and spark without being securely fastened together, causing sparking fires to start up quickly.


One drawback of aluminum wiring is its susceptibility to corrosion when in contact with certain metals. This leads to poor conductivity and additional heat production. An electrical repair service can inspect for corrosion signs before replacing damaged sections.


Due to its soft composition, aluminum wiring is more susceptible to wear-and-tear than copper, making it vulnerable to environmental conditions. Due to this risk, regular professional checks by an electrician are vital.

How to Manage Homes with Aluminum Wiring

Proper Inspection and Maintenance

Just because your home contains aluminum wiring doesn't mean disaster lies ahead—instead, it means being proactive about managing it. Hiring an electrical repair service to conduct an inspection would be wise, as they will assess its condition and provide any advice about upgrades or repairs as they see them necessary.

Upgrades and Replacements

Copper wiring upgrades may provide more permanent solutions that enhance home safety, value, and life safety. A professional electrical wiring installation service can complete this upgrade to ensure a safe electrical system within your residence.

Use Aluminum-Compatible Devices

If complete replacement isn't an immediate option, ensure all electrical components used during repairs or installations are compatible with aluminum wiring. Specific devices and connectors are designed specifically to work safely with aluminum wire, so make sure any electrician you hire for installations or repairs knows about these parts.

Finding an Electrician that Suits Your Needs

Certification and Experience

When dealing with aluminum wiring, make sure that you hire an electrician with certified experience who specializes in installing it as well as understanding any specific challenges associated with aluminum wire installations.

Regular Checkups

As with any initial inspection or upgrade, regular maintenance is key to protecting yourself and your home from electrical hazards. Retaining an electrical repair service for routine check-ups will allow them to identify potential issues early and reduce costly repairs in the future. This proactive approach may keep your family safer and help save on repairs in the long run.
