Aluminum Wiring Repair

Aluminum Wiring In Your Home – Many Problems

Aluminum wiring, once a popular choice for residential and commercial electrical systems due to its cost-effectiveness and availability, has been identified as posing potential safety risks. These risks stem from the inherent properties of aluminum, including its tendency to expand and contract more than copper, its susceptibility to corrosion when in contact with certain metals, and its relatively lower conductivity.

These characteristics can lead to loose connections, overheating, and in some cases, fires.

Given these risks, the repair or replacement of aluminum wiring in homes or businesses is a critical task that must be approached with care and professionalism, typically requiring the expertise of a licensed Colorado Springs electrician.

Identification of Aluminum Wiring

The first step in addressing the potential hazards of wiring with aluminum is to correctly identify its presence in a building’s electrical system. Aluminum wiring was most commonly installed in homes and businesses during the 1960s and 1970s. Visual inspection of wiring, typically at junction boxes, outlets, or switch plates, can help identify aluminum wiring, which is usually marked with the letters “AL” or the word “Aluminum” on the outer insulation.

Repair Options

Once the presence of this type of wiring is confirmed, there are several repair strategies that a professional electrician might employ:

Complete Replacement with Copper Wiring

This is the most comprehensive solution, involving the removal of all existing aluminum wiring and its replacement with copper wiring. This approach addresses the root cause of the potential hazards but can be costly and disruptive, as it often involves opening walls to access and replace wiring.


A more cost-effective method, pig-tailing involves attaching a short length of copper wire to the end of the aluminum wire at connection points (e.g., outlets, switches) using special connectors. These connectors, such as the UL-listed Al/Cu (aluminum/copper) type or the COPALUM crimp connector, are designed to mitigate the risks associated with aluminum wiring connections.

Pig-tailing can significantly reduce the risk of overheating and fire without the need for complete rewiring. However, this is not a complete solution and may not be acceptable in most situations.

AlumiConn Connectors

Similar to pig-tailing, this method uses special AlumiConn connectors that are specifically designed to securely join aluminum and copper wires. These connectors are considered a reliable, long-term solution for mitigating the risks associated with aluminum wiring.

Considerations for Repair or Replacement Of Aluminum Wiring

When contemplating the repair or replacement of aluminum wires in your home or business, several factors must be considered:

Safety: The primary concern is the safety of the building’s occupants. The chosen repair strategy should effectively mitigate the risks associated with aluminum wiring to prevent overheating and fire hazards.

Cost: The cost of repair options can vary significantly, with complete replacement being the most expensive. Budget constraints may influence the choice of repair method, but safety should not be compromised for cost savings.

Disruption: Some repair methods, particularly complete replacement, can be more disruptive than others, requiring extensive access to walls and potentially affecting the building’s occupants.

Local Codes and Regulations: Compliance with local building codes and electrical standards is crucial. A licensed electrician will be familiar with these requirements and ensure that any repair or replacement work meets the necessary standards.

Insurance Considerations: Some insurance companies may have specific requirements or offer incentives for upgrading from aluminum to copper wiring, recognizing the reduced risk profile of the latter.

“Soco Electric exceeded my expectations. They installed an outdoor hookup for a new hot tub. Everything ended up looking very built in, with the conduit even formed nicely around small bends of our siding. The price was very reasonable, and Jonathan is knowledgeable and good at explaining the work needed.” Ted Firlit
