"Ted and his crew were prompt, professional and got the job done in the time estimated. They understand how to deal with permitting, inspections and scheduling each step in the process. Specifically, Ted is very familiar with local nuances in each city, related to inspections. My house, being an older structure with older wiring and an oddly placed riser pole, was not a straight forward project, but it was no problem for the crew. They completed the work as planned, kept a clean job site and were very courteous throughout the project. I was very pleased with the work done by the Apollo and would hire them again and highly recommend them to others."

"Wonderful experience. Prompt, courteous, professional, honest and personable. They installed a new electrical panel which passed city inspection. The inspector complemented them on their attention to detail. An extra bonus for me was they accepted credit card payments, awesome! Will definitely hire them again for my next job."

"Saul and Juan arrived on time, determined where the fault lay, advised me on what I can do to save some labor costs by running wire myself. I have worked on some electrical equipment over the years so usually am familiar with what is needed or not needed. These guys didnâ  t try to sell me something I didnâ  t need. Very professional and I would recommend them to others. Thx. Brian Napa County"

"This company has my business from here on out from the first phone call to the end of the job or should I say jobs they have taken care of me and made me feel like I was being taken care of. Itâ s very hard to trust all contractors cause not all contractors care about what they do as much as about the check at the end these guys are different. They go out of their way to make sure that you are satisfied with what they are doing and there are no unnecessary change orders at all. I like to thank you guys personally for always making sure my knee your met."

"The team at Avant is next level. From planning, to prep and through final inspections, Avant’s skilled approach allows the home-owner to get from ideation to ”finished” without any pressure to do more than our budget allowed. We upgraded our panel; moved the PG&E drop so the wifi meter was no longer next to our master suite; installed a new EV fast-charger; installed a new home security system; upgraded indoor and installed new automated outdoor lighting AND re-wired all our 220a appliances. I’d recommend Avant for any home-owner seeking high value excellent workmanship!"

FAQs for electrical wiring or panel upgrade projects in Los Altos, 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.
