"Ross was very helpful and patient with our project. We had a lot of questions about upgrading our panel and adding a sub panel for a hot tub and outdoor conduits. He was prompt with calling and texting and has been very responsive with getting the project moving from the start."

"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."

"Jacob installed my new EV charger. He did an excellent job taking great care in cutting my drywall in the garage to access the main panel outside and then place the wiring in a manner that was as hidden as possible- all at a very fair price. I would recommend him highly and will call on him for future jobs."

"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!!"

"I contracted with Hector for two electrical projects. The first was for replacement of our 200 amp electrical panel. One problem I've had with contractors has been frustration at their lack of communication. Hector was always good at answering my calls, returning text messages, and keeping me informed. He did his work professionally for a reasonable price, so I hired him again to wire our shed. Again, he did the work professionally and kept me informed of his schedule. One area for improvement would be for him to pay more attention to what the customer says. Some work in our shed had been previously started with Romex installed through the studs. I told him this would need to be replaced with conduit per code. He again started installing Romex. He said he thought we would be installing sheet rock and it would cost more to change to conduit. But after I pointed out I had included flexible conduit in the written scope of work, he made the change with no additional cost or complaint."

"We submitted a service request through our AHS home warranty and were assigned to Budget Electric. It was after work hours. It affected our fridge and stove, so AHS put it as expedite/emergency. The next morning we were contacted by BE, and they found us a canceled appointment time for the following morning. In the meantime, I searched BE for reviews and saw quite a few negative reviews, leaving me nervous for our appointment. Based on the service we received, I don't know how they have bad reviews. The women answering my phone calls were very understanding and patient with may many phone calls. Michelle and another woman handled all my questions and concerns. There were a couple of times I wasn't able to reach them, but I'm assuming they were handling other calls or were at a unch break. Although it was an hour outside of our service window, we had an electrician show up soon after. With the storms, I think they're busy and sometimes run a little behind. Michael was the best and completely blew away all concerns as soon as he arrived. He was courteous and positive the entire time. He asked permission for coming inside, opening doors, going into rooms, etc. He patiently explained everything he did. He wasn't annoyed by curiosity or my questions. He was thorough and had diagnosed our problem in less than 5 minutes. Although it ended up being an issue for PG&E to fix, Michael double-checked the circuit breaker and boxes. He replaced a faulty fuse box to ensure no additional issues. After our service was complete, I shared our initial concerns based on previous reviews. Michael was still positive and genuinely courteous. He had positive things to say about Miguel and Abraham as well. He explained they have a high volume of service calls. He didn't make excuses. Without dismissing the other reviews, he said that with the volume of calls they do, there are probably some negative reviews. Although I don't typically leave reviews, I felt it was only fair to give an honest review after reading the negative reviews. Thanks to BE and Michael for service above and beyond!"

FAQs for electrical wiring or panel upgrade projects in San Mateo, 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.
