If your home was built between 1968 and 1972, there’s a good chance it was wired with aluminum instead of copper. While aluminum wiring was a common practice during that time, it is now known to pose serious fire risks if not properly maintained or retrofitted. Testerman Electric offers professional aluminum wiring retrofitting services throughout Maryland, Southern Pennsylvania, and Delaware—specializing in safe, code-compliant upgrades using Alumiconn® connectors, the industry standard for permanent, safe aluminum-to-copper connections.

Why Aluminum Wiring Is a Safety Concern

Aluminum expands and contracts more than copper when electrical current flows through it. Over time, this movement can cause connections to loosen, leading to:

• Overheating

• Arcing (sparks)

• Melting insulation

• Electrical fires

In fact, the U.S. Consumer Product Safety Commission (CPSC) has linked aluminum wiring in homes to a significantly higher risk of fire compared to homes wired with copper.

What Is Aluminum Retrofitting?

Rather than replacing all your home’s wiring—which can be costly and invasive—retrofitting allows us to make safe, permanent upgrades at the connection points using Alumiconn® connectors. These specially designed devices create a secure aluminum-to-copper connection at outlets, switches, light fixtures, and junction boxes.

Our Aluminum Retrofitting Process

1. Home Evaluation: We identify all devices and connection points where aluminum wiring is present.

2. Alumiconn Installation: Our electricians install Alumiconn® connectors to bond aluminum wire to short copper pigtails, which are then connected to your devices.

3. Safety Testing: We test each connection for safety and performance to ensure everything meets code requirements.

4. Full Compliance: All retrofitting is performed according to National Electrical Code (NEC) standards and CPSC recommendations.

Why Choose Alumiconn® Connectors?

• CPSC-Recommended: Alumiconns are one of the only solutions recognized by the U.S. Consumer Product Safety Commission for aluminum wire retrofitting.
