Point Loma Home Pros has published a guide detailing the costs and safety considerations involved in converting residential electrical wiring from aluminum to copper, a relevant concern for San Diego homeowners with older properties. The resource covers cost breakdowns, safety data, and practical guidance for those whose homes contain aluminum branch-circuit wiring installed between 1965 and the mid-1970s.

The guide comes as data from the U.S. Consumer Product Safety Commission shows that homes with aluminum branch-circuit wiring are up to 55 times more likely to have outlets reach hazardous temperature conditions than copper-wired homes. In San Diego, aluminum wiring became widespread during this period as copper shortages and rising prices pushed builders toward lower-cost alternatives.
The financial implications of addressing aluminum wiring vary based on home size, layout, and accessibility. According to Point Loma Home Pros, rewiring costs for San Diego homes typically range from $7,000 to $15,000 or more, with major cost drivers including the number of circuits, access behind finished walls, whether electrical panel upgrades are required, and local labor rates.
Upgrading to copper wiring delivers benefits that extend beyond fire prevention, according to Point Loma Home Pros. Homeowners who complete the conversion may see reductions in insurance premiums, as outdated electrical systems are among the leading causes of non-weather-related claims.
Copper is also described as offering better electrical performance, with conductivity rated near 100% on the International Annealed Copper Standard compared to aluminum's 61% — supporting stable power delivery for modern appliances and technology.
Copper's melting point of 1,085 degrees Celsius also far exceeds aluminum's 660 degrees, adding to the material's fire safety advantages. Point Loma Home Pros notes that homes with copper wiring throughout tend to command higher resale values and attract more buyers, as aluminum wiring is frequently flagged during inspections and can stall negotiations or lead to reduced offers.
For these reasons, Point Loma Home Pros emphasizes the continuing importance of aluminum-to-copper rewiring, with even partial work noted as a viable option.
"Partial rewiring is possible, focusing first on high-risk circuits like kitchens, bathrooms, or bedrooms," a Point Loma Home Pros spokesperson said. "Work with your electrician to plan phases, maintain permits and documentation, and understand that remaining aluminum still carries increased fire risk."
