"William and his team did a fantastic job upgrading our meter panel. They took care of all the permits and had the job done on time and on schedule. They were extremely communicative throughout the entire process and I would use them for all electrical services in the future."

"Chris showed up on time. completed the work in a timely manner. He cleaned up after the work was completed. His price was fair and offered to attach the ceiling fan to the wall switch. Several other electricians I contacted did not offer this and one refused, telling me to buy fans with remotes. Chris kept us informed as to how the job was progressing. We are going to have can lighting installed in our master bath and will us him again. I would highly recommend him for any electrical work."

"We are very pleased with the quality of the work. None of our lighting, pool equipment or outdoor electrical was working properly and Fairway Electric identified the problem immediately. After running a new line and rewiring existing outlets, we now have power to the entire backyard and it is much safer now."

"I recently hired Mazen from Smart Electrical Solutions for a multi-stage project at my home, and I couldn't be more impressed with the results. The project was complex: a full electrical panel upgrade, a complete layout of recessed lighting, and some tricky troubleshooting of older circuits that had been giving me trouble for years. Mazen handled the panel upgrade with incredible precision. The wiring is remarkably clean and organized, and he took the time to clearly label every single breaker—something my previous electrician overlooked."

"I reached out to Electric Zone for a few items we wanted in our home; a couple outlets installed in our closets and assistance in wiring a new pendant light. Haik from Electric Zone called us and arranged to come by the same day we reached out so that he could come by and provide an estimate, the price was fair so we decided to move forward with them. When Haik and his coworker arrived they discussed every step with us before proceeding, we were very happy with the options and works provided. Definitely recommend, we will be reaching out to Electric Zone again if we need more work in the future."

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

FAQs for electrical wiring or panel upgrade projects in Mount-wilson, 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.
