Local Electrical Services in Berkeley, CA 94702 - McCarthy Electric

Our residential electrical inspections are thorough safety reviews. We check your main service panel for proper amperage and safe connections, test GFCI and AFCI outlets (crucial for older homes), inspect wiring conditions, and evaluate the grounding system. Given Berkeley's many historic properties, we pay special attention to outdated components like knob-and-tube or aluminum wiring that may pose a fire hazard, providing you with a clear, prioritized report on any necessary repairs or upgrades for your safety and peace of mind.

Absolutely. Aluminum wiring, common in homes built between the mid-1960s and late 1970s, is a known local issue due to its tendency to oxidize and loosen at connections, creating overheating points. Our team is experienced in addressing this specific hazard. We don't just recommend a full rewire as the only solution. We can perform a detailed assessment and often implement COPALUM crimp connectors or AlumiConn lugs—approved, permanent repairs that mitigate the fire risk by creating a secure, corrosion-resistant connection between the aluminum wiring and your devices, bringing your home up to modern safety standards.

Electrical work is governed by strict California building and safety codes (Title 24) for your protection. As a licensed California State contractor since 1993, we guarantee all our work meets these codes, which is essential for safety, insurance, and resale value. Licensure also requires ongoing education, so we're current on the latest standards, including those for outdoor lighting corrosion resistance in Berkeley's moist climate. More importantly, we carry the proper insurance, protecting you from liability. For the safety of your home and family, complex installations and repairs should always be handled by a licensed professional.
