Home Rewiring FAQ for San Francisco Homeowners

How often should San Francisco homeowners get home rewiring?
Given San Francisco's karl the fog: persistent summer fog from the pacific keeps temperatures at 55–65°f on the west side, most homeowners benefit from home rewiring at least once a year. Year-round fog moisture causing wood rot and paint peeling on west-facing Victorians often makes spring or fall the optimal time to schedule service.
What home types in San Francisco most need home rewiring?
Victorian Painted Ladies and Edwardian flats (most common exterior) and Spanish colonial and stucco in the Sunset and Richmond districts are the most common home types in San Francisco and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How do I know if my home needs rewiring?
Signs include knob-and-tube wiring (visible in attic/basement), two-prong outlets throughout the home, aluminum wiring (common in 1965–1973 homes), frequent breaker trips, flickering lights, or a panel under 100 amps.
How much does whole-home rewiring cost?
Full rewiring of a single-family home typically runs $8,000–$20,000 depending on square footage, construction type, and scope. It's significant but eliminates major fire hazard and is required for many insurance policies.
Do I have to move out during rewiring?
Not necessarily. We work room by room, maintaining power to other areas. However, in some cases temporary power or phased occupancy is easier and we'll plan accordingly.
Is aluminum wiring dangerous?
Aluminum wiring itself isn't necessarily dangerous, but connections can loosen and overheat over time. COPALUM crimping or AlumiConn connectors at all connections remediate the risk, and in many cases full rewiring is recommended.
