"Gridwise installed a hardwired Level 2 charger for us and it was refreshingly easy. We did a quick video inspection, got a clear estimate, and then they showed up on schedule and knocked it out. The wiring is clean, no mess left behind, and they took a minute to explain the configuration/settings so it made sense. After dealing with contractors who disappear or complicate everything, this felt efficient and professional. Would use them again."

"James is an awesome owner and wonderful to work with! He sent Danny and another person to complete our lighting job. They did A LOT of work installing recessed lighting in 3 rooms and installed under cabinet lighting in our kitchen. They finished all in 1 day and we were very pleased with the work they did! We will definitely be hiring Bay Area Electric again and I will definitely ask for Danny!"

"Steve and his crew of electricians did a fabulous job. They basically replaced the entire house’s electrical, all new switches and outlets in addition to all the new light fixtures in every room. They showed up on time, did what they said they would and addressed every issue encountered in the rehab. In addition, Steve was great helping me decide what to put where. An overall excellent experience. I would HIGHLY recommend Warner Electric for any electric job."

"We were very lucky to find Emrom Electric and Emmanuel Mbisse. Our 100+ year old house in Berkeley needed complete rewiring after a short circuit and inspection. Emrom was able to start this huge job within a week or two, saving us a lot of money in tenants' dislocation expenses. Emmanuel was a pleasure to work with, providing explanations and giving us options along the way. He got the job done faster than we had hoped in a good, professional manner for a fair price. We would recommend Emrom to anyone and will definitely be contacting them for any future electrical work."

"Electric supply-panel and gooseneck were pulled off house by downed utility power line in storm. Got call from AC shortly after posting for help on HomeAdvisor. They were nearby, came over promptly, coordinated with PG&E to reattach supply and replaced the panel and gooseneck in the same day and at a very reasonable cost. Needless to say I was very happy with the result. Definitely 5 stars."

FAQs for electrical wiring or panel upgrade projects in Mill Valley, CA

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
