"I needed my electrical sub panel upgraded and Ivan and his team were amazing. They made what could have easily been a very stressful project a breeze. I was very impressed and satisfied with their work and will be calling them for future projects we have planned."

"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."

"On Saturday, July 20th I logged into the website for Wire Tech Electric and requested someone come out to my house to give me a quote to add a Level 2 electric vehicle charging station into my garage for my new Chevy Bolt. I received an email back from Olvin Rivera later that evening and we arranged to meet on Wednesday afternoon (July 24th) for the free quote for the installation. Olvin texted me prior to the scheduled time to let me know he was on his way. I already knew that my existing 220-amp breaker panel was full and after he arrived we discussed adding a subpanel into the garage to contain the 40-amp breaker for the 240-VAC level 2 charging station. Across the board, Olvinâ s prices for the work and materials was better than the prices listed for Amazonâ s professional installation for any of their level 2 chargers. He emailed me a copy of the quote and I decided to go with his team. This morning Olvin texted me prior to his scheduled time to inform me that he was heading over to do the install. He and a helper came out to the house and extended the main breaker panel into the garage and added the subpanel, 6-gauge wire (rather than the smaller 8-gauge wire that was minimally required) and terminated everything to a NEMA 14-30 outlet. Everything was professionally installed, the breakers were tested and frankly it really looked like it belonged there. Ten minutes after they left UPS delivered the TurboDX charger that I had ordered. Unfortunately, the TurboDX charger required direct connection to the power source rather than through the NEMA plug. Luckily, Olvin Rivera from Wire Tech Electric was able to return where upon he removed the NEMA plug and modified the wall connection to allow the power to be connected directly to the charger. The TurboDX charger was a problem from the get-go as although the charger came in a nice aluminum casing, the casing needed to be drilled out to allow the electrical feed to enter from the back into the housing. Olvin had the necessary tools to get the casing drilled out and inserted a plastic knockout bushing to protect the wiring through the hole. Then he leveled and attached the charger to the wall and connected the power directly to the charger. He also called the tech support hotline for the TurboDX charger to ensure everything had been properly connected (the installation instructions for the TurboDX charger were a little too basic for what we were doing.) Everything worked and the vehicle charged the last 60 miles until full charge in just under 2 hours. I really liked the way Wire Tech Electric kept in contact with me throughout the process from answering my request for a quote, then sending me the full quote after we discussed the work to be done, the text messages prior to arrival to let me know to expect them and their promptness to arrive within the designated appointment time. I found Olvin and his helper (whose name I have forgotten) to be very professional and courteous and the work was first rate. I will definitely keep them in mind for any future electrical contract work."

"Mr. Arechiga disconnected our old knob-an tube and grounded our 2 story home. We also had him upgrade our main panel to 200A solar ready. His responsiveness and professionalism made us feel safe and made this experience extremely easy. He was able to accommodate us within the week we highly recommend him!!"

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.
