    We begin with a formal load calculation, then recommend the safest path forward: a main panel upgrade, a service upgrade, or a properly sized subpanel. We also evaluate grounding, bonding, working clearances, labeling, and arc‑fault or ground‑fault protection to align with current codes and reduce future maintenance issues. Our process is designed to minimize disruption and keep the project moving by coordinating closely with inspectors and utilities.

    Safety & Upgrade Insights for Mill Valley

    Breaker panels typically last 25–40 years. Frequent tripping, scorch marks, rust, buzzing, or warm breakers are warning signs your panel needs attention. A faded or incorrect directory is another risk. Every upgrade we perform ends with a clean, accurate circuit map so future troubleshooting is faster and safer.

    Choosing between a main panel upgrade and a subpanel depends on total load, feeder size, available service, and your long‑term plans. If your wiring is original or you’re planning a large remodel, also review our whole‑house rewiring service to address safety and performance comprehensively.
