Repairs and installations ask different things of an electrician. A repair is detective work: find the fault, fix it safely, and leave the circuit better than you found it. An installation is planning work: size the load, pull the permit, run new circuits and pass inspection. The best electricians are good at both, and that’s the test every company on this short list had to pass.

Repair or installation? Why the difference matters
| Repairs | Installations | |
| Typical jobs | Dead outlets, tripping breakers, flickering lights, faulty switches | EV chargers, new circuits, lighting, panels, solar and batteries |
| What matters most | Speed and accurate diagnosis | Load planning, permits and inspection |
| Permit | Rarely for like-for-like fixes | Usually required |
| Timing | Same day or next day | Scheduled, sometimes weeks out |
| What to ask | “What caused the fault?” | “Can my panel carry the new load?” |
Each electrician below is profiled on both sides of that line.

Before a repair: a 4-point checklist
- Note the symptom. Which breaker tripped, what was running, and whether there was heat, a smell or a sound.
- Make it safe. Switch off the affected circuit if you can reach the panel safely.
- Ask about the fee. Find out whether there’s a service-call fee and whether it goes toward the repair.
- Ask for the cause. A good electrician explains what failed before quoting the fix.
Before an installation: a 5-point planning checklist
- Check capacity. Ask for a load calculation to confirm your panel can carry the new equipment.
- Confirm the permit. New circuits, chargers, panels and solar usually need one. Ask who pulls it.
- Plan the location. Decide where the charger, fixtures or battery will go before the quote.
- Ask about rebates. Utilities and cities often offer EV charger and efficiency rebates.
- Get the scope in writing. The quote should list parts, labor, permit fees and warranty.
Homeowner questions
Should I use the same electrician for repairs and installations?
It helps. An electrician who repairs your system learns its weak points, which makes later installs smoother. Make sure the company is strong at both, and pick a specialist for complex installs like solar and batteries.
Do installations always need a permit in California?
Most do. New circuits, EV chargers, panel upgrades, generators and solar generally require a permit and inspection. Like-for-like repairs usually don’t. A licensed electrician confirms the rule for your city and handles the paperwork.
How long does a typical installation take?
A single EV charger or new circuit often takes a day, plus time for the permit and inspection. Panel upgrades can need utility coordination, which adds days or weeks. Ask for a timeline with the quote.
How do I verify an electrician’s license?
Search the license number or business name on the CSLB website. Confirm the license is active and classified C-10, and that bond and workers’ compensation details are current.
