"Excellent service. I needed to upgrade my electric panel, Ben did an excellent job very professional. Installing switches, circuit breaker panels, relays, and other electrical control and distribution equipment was the right call. I look at several electricians with reasonable prices and CA Electrical Group was definitely the right call. I will highly recommend CA Electrical Group to all my friends. What was important to me was his daily commitment to start and finish the job the dates we agreed on."

"They did a solid job upgrading my main electrical panel. Dave from Horizon was professional, showed up on time, and explained everything clearly before starting. The new panel looks clean and professional, and the whole process went smoothly with minimal disruption. I feel much safer now with updated breakers and better capacity. Would definitely recommend Dave and Horizon to anyone needing electrical work done right."

"Had to have additional circuits added to my panel, some wiring, plugs and GFCI outlet. Hamilton Electric did a professional job quickly and efficiently. Brian explained everything along the way and made sure I was satisfied. He is honest and fair, old school, the way service used to be. Price was great, too."

"Edgar is very detailed, respectful, professional with very good customer service! He showed up on time and completed the electric panel change sooner than expected! I have already referred him to my cross the street neighbor, Diane. Hopefully she will reach out soon for an estimate to change out her electrical panel too. Thank you ð ð"

"We contracted JC Electric to install an outlet in our bathroom, install an overhead fan , replace a hanging lamp over our kitchen table, add two timers to light switches, and brought our electric box up to code. We were very impressed with Jaimie and his staff. Very professional, very good at communicating with us. We found JC Electric (Jaimie) to be very honest and reliable. We highly recommend him."

Customers say: True professional

"Ivan and Edgar were amazing! I originally brought them on board for an EV charging outlet to be installed in my detached garage. After a quick assessment, we learned I would need to have a new electrical panel installed and a new line run under the home to the garage. The work was done quickly and flawlessly. Their price was also very competitive to many of the quotes I was provided from other teams. On top of that, Ivan and Edgar were extremely professional and friendly. I plan to also hire them for a recessed lighting project in my living room, which I learned is their specialty. Thank you IC Electric for an amazing instal!"

"We had a great experience with OSJ Electric working on our garage remodeling project. Ossamu is a very detail oriented person, he thinks out all the possible options and comes up with the final solution. We got our electric panel upgraded, adding another panel and new wiring for adding more capacity, cleared all the walls of conduits and external wiring, running everything inside, installed recess lights, multiple new outlets, new focus lights on the outside moved solar panel to clear wall space and installed Tesla EV charger. The final outcome was much better than what we envisioned. Ossamu’s work is beyond expectation. He is creative and comes up with solutions to any electrical need we have. Their pricing is reasonable for the quality of work and service. I will highly recommend OSJ for any electrical work and would definitely go with them for any future electrical projects."

FAQs for electrical wiring or panel upgrade projects in Danville, 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.
