McLaren Electric Inc. completed a major electrical upgrade for a duplex in San Mateo to address insurance requirements and improve the property's electrical safety.
The project included removing the existing knob-and-tube wiring and replacing it with a modern grounded electrical system. We also replaced an outdated Federal Pacific electrical panel and an older fuse box with modern circuit-breaker panels.
One of the existing subpanels was located inside a closet. Our team relocated it to a safer, code-compliant location where it remains readily accessible and maintains the required working clearances.
This project gave the duplex a safer and more dependable electrical system while addressing several common concerns found in older San Mateo properties.

Older wiring was never designed for today's electrical loads, and many insurers will no longer cover it. We replace knob-and-tube and other outdated wiring with modern grounded circuits in single-family homes, duplexes and small multifamily buildings.
