Frequently Asked Questions

Do I need an electrical panel upgrade for an EV charger or heat pump?

Not necessarily. We assess existing demand, circuit space, equipment condition and the new load. The result may be a dedicated circuit, compatible load management, or a panel and service upgrade. A 200-amp panel is not a universal requirement.

What affects the cost of electrical work in Mill Valley?

Price depends on the type of repair or installation, how easy the wiring is to reach, the equipment, and any meter, utility, permit or patching work. We assess the project and explain exactly what the estimate includes.

How do permits work for electrical projects in Mill Valley?

Mill Valley lists panel, main-service and subpanel work in its permit process. EV chargers and batteries have their own requirements. Confirm whether the address is within the City or unincorporated Marin. See Mill Valley electrical permit process.

Does an older Mill Valley home need rewiring?

Not always. Tell us which rooms are affected, what work was added in earlier remodels and whether you have plans or records. That lets us assess the existing circuits and the proposed work together instead of assuming the whole house needs rewiring.

What electrical upgrades should I consider for an older home?

Upgrades to consider are GFCI outlets, 200-amp panels, dedicated circuits for appliances like EV chargers, and whole-home surge protectors.

Can you coordinate electrical work with other home services?

Yes. We offer plumbing, HVAC, water heater, and finishing work that can align with your electrical project.

Why does my GFCI outlet keep tripping?

This could be because water got into the electrical box, there is an issue with the downstream wiring, there is a faulty appliance or cord, or the outlet itself is failing.

What should I do if an electrical outlet feels hot?

If an outlet feels hot, the best thing to do is unplug all appliances from the outlet and turn off power to that part of the house in order to prevent a fire before an electrician can arrive.

What are the warning signs of an overloaded electrical panel?

An overloaded panel can cause flickering lights, frequent breaker trips, the sound of electricity buzzing from the panel or outlets, and scorch marks on the panel.
