What Is Aluminum Wiring and Why Does It Matter?
Aluminum wiring was widely installed in residential homes during the 1960s and 1970s when copper prices surged dramatically. At the time, aluminum was seen as a cost-effective alternative. However, decades of real-world performance revealed critical safety shortcomings that make aluminum wiring a serious concern for homeowners in Rib Mountain, WI today.
Unlike copper, aluminum expands and contracts at a significantly higher rate when electricity passes through it. Over time, this constant movement causes wire connections to loosen at outlets, switches, and breaker panels. Loose connections create electrical arcing, which generates intense heat and is one of the primary causes of residential electrical fires.
Additionally, aluminum oxidizes when exposed to air, forming a layer that is far more resistant to electricity than copper oxide. This resistance generates heat at connection points, further increasing the risk of fire. Homes with aluminum wiring are statistically far more likely to experience connection failures that reach fire-hazard conditions than homes wired with copper.
Important Safety Notice
The U.S. Consumer Product Safety Commission has identified homes with aluminum wiring as being 55 times more likely to have one or more wire connections at outlets reach "fire hazard condition" than homes wired with copper. If your home was built between 1965 and 1973, have it inspected promptly.
Signs Your Home May Have Aluminum Wiring
Many homeowners do not realize that their house has aluminum wiring until a professional inspection uncovers it. Aluminum wiring, commonly used in homes built between the 1960s and early 1970s, can pose safety risks if not properly maintained. By learning to identify the signs of aluminum wiring such as wires labeled with “AL” or connections that appear oxidized or discolored you can address potential issues early, reducing the risk of electrical hazards.
- Home was built or renovated between 1965 and 1979
- Flickering or dimming lights that are not caused by bulb issues
- Warm or discolored outlet covers and switch plates
- Burning or unusual plastic-like smell near outlets or panels
- Frequent tripping of circuit breakers without obvious cause
- Outlets or switches that feel hot to the touch
- Silver-colored wires visible at the electrical panel
- Lights that flicker when appliances cycle on or off
Our Aluminum Wiring Services in Rib Mountain, WI

Comprehensive Inspection
We conduct a detailed inspection of all wiring, outlets, switches, and your electrical panel that can be safely accessed. During this process, we specifically look for any connections involving aluminum wiring and carefully evaluate their current condition to determine if any issues or risks are present.
COPALUM Crimping
We use the COPALUM method, which is approved by the U.S. Consumer Product Safety Commission (CPSC). This method permanently connects copper and aluminum wires using a specially designed connector and a crimping tool. The process creates a secure and durable connection that meets safety standards for electrical wiring.
Pig-Tailing with AlumiConn
The U.S. Consumer Product Safety Commission (CPSC) has certified the COPALUM technique, which we employ. This technique uses a crimping tool and a specifically made connector to permanently join copper and aluminum wires. The procedure produces a strong, long-lasting bond that satisfies electrical wire safety regulations.
Full Rewiring
For older homes that still have extensive aluminum wiring, we provide a full rewiring service using modern copper wiring. Aluminum wiring, commonly installed in homes built before the 1970s, can pose safety risks such as increased chances of overheating, corrosion at connections, and potential fire hazards. By replacing it entirely with copper wiring, our service eliminates these risks and ensures that your home’s electrical system meets current safety standards and building codes. This upgrade not only improves safety but also enhances the reliability and longevity of your home’s electrical system.
Our Inspection and Remediation Process
We follow a structured, step-by-step approach to ensure no detail is overlooked. Every technician at Palace Electrical Service is trained specifically in aluminum wiring remediation procedures.
Initial Consultation and Visual Assessment
During this first step, we discuss your home's history, including the age of the wiring and any prior electrical work that may have been done. We then perform a visual assessment of your electrical system, examining the panel, visible wiring, and accessible outlets or junctions. This helps us identify where aluminum wiring is present and estimate its overall condition, which sets the stage for a more detailed inspection.
Detailed Wiring Survey
Our electricians conduct a thorough inspection of your electrical system. This includes opening every outlet box, switch box, and junction point for light fixtures to carefully document all aluminum wire connections. Each connection is evaluated to determine whether it is safe and functioning properly or if it requires immediate remediation. This step ensures no areas of concern are overlooked.
Remediation Plan Presentation
Based on the detailed survey, we create a clear and itemized remediation plan. This plan outlines exactly which connections need repair, the methods and materials we will use, and a full breakdown of costs. Our goal is transparency there are no hidden fees or unexpected charges so you know exactly what to expect before work begins.
Remediation Work
Once you approve the plan, our team carries out all necessary remediation work. We use only approved connectors and industry-standard methods to ensure long-term safety and reliability. After the work is complete, all areas are cleaned and restored to their original condition.
Post-Work Inspection and Documentation
Finally, we perform a comprehensive inspection of every connection to verify that all work has been completed correctly. You receive written documentation detailing the repairs and methods used, which can be kept for your home records or submitted to your insurance company if needed.
