There is no room for compromise when it comes to the safety of your home’s electrical system.

As a licensed Copalum contractor, our team is specifically trained to implement the high-pressure cold-weld technology required to secure your home against potential fire hazards. If your home was built between the mid-1960s and late 1970s, you likely have aluminum wiring, which requires specialized attention that standard electrical repairs simply cannot provide.

What Is Aluminum Wiring and Why Is It Dangerous?

During the 1960s and 70s, a spike in copper prices led builders to use aluminum wiring as a cost-effective alternative. While aluminum conducts electricity, it possesses physical properties that make it far more hazardous than copper in a residential setting. Aluminum is prone to “cold flow” and thermal expansion, meaning the wire expands and contracts significantly when heated by electrical current.

This movement causes connections at outlets and switches to loosen over time. Furthermore, aluminum oxidizes quickly. This oxidation creates high resistance, which generates intense heat. According to the Consumer Product Safety Commission (CPSC), homes with aluminum wiring are up to 55 times more likely to have one or more wire connections reach fire-hazard conditions than homes wired with copper.

CPSC-Recommended Solutions

The Consumer Product Safety Commission has conducted extensive research into electrical fire prevention wiring repair. They have identified only a few methods that provide a permanent fix for hazardous aluminum wiring. While many electricians suggest “pigtailing” with standard twist-on wire nuts, the CPSC considers this a temporary fix at best. The gold standard for safety is the Copalum repair method. This is the only repair system that creates a permanent, oxygen-free bond between aluminum and copper, effectively eliminating the risk of overheating at connection points.

What Is the Copalum Repair Method?

The Copalum repair method utilizes a specialized copalum connector installation process. Unlike standard crimping or wire nuts, the Copalum system uses a proprietary high-pressure tool that exerts over 10,000 pounds of pressure to “cold-weld” the aluminum wire to a copper tail. This process creates a solid-state bond that is airtight and permanent. By effectively turning the problematic aluminum connection into a stable copper interface, we eliminate the oxidation and loosening issues that lead to electrical fires. Because this method requires specialized equipment and rigorous certification, only a select number of contractors are authorized to perform this service.

Frequently Asked Questions

Is Copalum better than a total home rewire?

A total copper rewire is the only other CPSC-approved permanent solution, but it is incredibly invasive and expensive. Copalum provides the same level of safety and reliability at a fraction of the cost and with significantly less damage to your walls.

How long does the Copalum process take?

Depending on the size of your home, a professional Copalum retrofit typically takes between two to four days.

Will my insurance company accept Copalum repairs?

Yes. Most insurance companies recognize the Copalum repair method as a permanent solution to aluminum wiring hazards and may even require it to maintain your homeowner’s policy.
