"I am updating my rating for CA Electrical (Unfortunately Angi will not allow me to edit, so I am posting this as a new review). After posting my original review I was contacted by CA Electrical. The supervisor assured me that my experience was not their normal practice and that they normally made sure to call if there was a change of plans. I felt that they were earnest in trying to make things right, so I agreed to give them another chance. I ultimately decided to select them for my project to replace sub panel and install outlets. The crew was excellent and professional. They showed up on time, were professional and friendly, took extra care to ensure work spaces were left clean. Their workmanship was excellent and they did a great job of cleaning up some messy electrical wiring that had been there before. As an electrical engineer, I also appreciated the crews knowledge of code and ability to explain the technical side of the installation. I would use them again."

"I can’t say enough good things about Hamilton Electric. They completely rewired two rooms in my home, running all-new wiring all the way back to the electrical panel. The work also included adding additional outlets and installing new lighting in both rooms and the closets. The quality of work was excellent—clean, professional, and done right. The value for the amount and quality of work completed was outstanding, and I felt like I got excellent service for the price. Communication was great throughout the entire process. He took the time to explain everything he was going to do before starting and kept me informed every step of the way. He was professional, knowledgeable, and clearly takes pride in his work. I would absolutely recommend Hamilton Electric to anyone looking for quality electrical work, great communication, professionalism, and excellent value. If there were a 10-star button, I’d give them all 10!"

"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 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 Walnut Creek, 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.
