"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."

"Ray gave me a call while I was in the process of finding an electrician to troubleshoot a wiring problem at our office space. I told him that some of the outlets were working while some of them were temperamental. Ray came to the office with a sense of urgency, and not only checked out the electrical panel, but looked at every individual outlet that was not working. He explained what the problem was in great detail, and was very confident that he could fix the problem, and scheduled for two of his workers to come out the following day to tackle the issue. They were able to fix it in about an hour, and everything is working perfectly now. I immediately asked for a way to give a review, so here I am right now. 10/10!!!"

Customers say: True professional

"I purchased a small wine cooler from Wayfair and needed installation. Before that could be done, I need electrical to the cabinet where the wine cooler would go. Ivan did the whole job for me and it looks great! I can hardly wait to use it! Ivan and his assistant were diligent and cleaned up the mess that gets made when doing work of this kind. He communicated everything that I needed to know and was very professional. I will definitely use him again."

"Michael showed up on time and even called me as he was on his way to my home which I appreciated. He not only fixed my issue buy also explained to me how things work electrically. I would hire them again for any electrical issues and hope I get Michael again. Your company is lucky to have him."

"I had an outstanding experience with Mister Sparky. They installed a new electrical outlet in my master bedroom, and the entire job was completed in less than an hour. From the moment they arrived, the technician was punctual, courteous, and highly professional. The quality of the workmanship exceeded my expectations. Everything was installed neatly, tested thoroughly, and the work area was left spotless. It’s refreshing to work with a company that values both craftsmanship and customer service. If you’re looking for a reliable, knowledgeable, and efficient electrician, I highly recommend Mister Sparky. They made the entire process quick, stress-free, and delivered exceptional results. I wouldn’t hesitate to use them again for any future electrical work."

FAQs for electrical wiring or panel upgrade projects in Castro 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.
