21st Century Services

I’m an experienced residential electrician’s helper/tech with 5 years of hands-on work under a licensed electrician, with a focus on home backup systems. I handle the full range of residential electrical work, from a single new outlet or switch to main panel replacements, subpanels, transfer switches, generator hookups, and whole-home backup setups. Backup power is what I specialize in: standby generators, interlock kits, automatic transfer switches, inlet boxes, and tying essential circuits so the house stays on when the grid goes down. What you can expect: • Clean, code-conscious work and a job site left tidy • Clear explanation of what’s needed before anything is opened up • Practical recommendations (what actually helps in an outage vs. what you don’t need) • Coordination with the licensed electrician on permitted work, inspections, and panel/service changes Typical jobs: • New outlets, switches, lighting, and dedicated circuits • Kitchen, bath, garage, and outdoor electrical • Circuit breaker troubleshooting and panel work • Main panel and subpanel replacement / upgrades • Generator, transfer switch, and home backup system install • EV charger and other high-load circuits (when the service can support it) If you’re in the East Bay or nearby and need something done right the first time—whether it’s one outlet or a full backup system—send the details and photos. I’ll review the job and get you a straightforward plan and quote.
