The folks over at South Bay Electric Company have been awesome. I can tell Ian is super busy but he…read morehas been very helpful with discussing my particular issue over the phone and text. They helped me prolong the life of an outdated main panel, and I will definitely be using them to replace it soon. This is in contrast to another company that quoted me almost twice as much for a panel replacement and seemed to employ scare tactics to try to get me to sign. After the initial service, there was an issue that was arguably unrelated, but Ian promptly sent someone out to fix the issue without fuss because it had gone unnoticed during the first visit. I also have nothing but good things to say about the folks working under Ian. They were all easy-going and willing to spend the few extra minutes to answer my questions, so that I understood the problem and the solution. Happy I finally found my go-to electrician!

Highly Recommended - Excellent Service…read more Great service from South Bay Electricians! They helped us resolve a challenging electrical issue in our home, and the entire experience was excellent from start to finish. Derek and Tyler were thoughtful, polite, and highly professional throughout the process. They took the time to thoroughly explain what was going on and kept us informed every step of the way. Despite the difficulty of the situation, they were able to identify the root cause, an obscure line break hidden behind a closet where no panel even existed. Their attention to detail and expertise were impressive, and they were able to fix the issue completely and restore everything to proper working order. We were extremely pleased with their work and professionalism. We would absolutely hire them again and highly recommend South Bay Electricians to anyone in need of reliable, skilled, and courteous electrical service.

There's an open space between my panel…read moreand my garage, so I was told by other electricians that I'd have to get someone else to break the concrete because they don't do that. These guys were one of the few that could handle the concrete work, and they also handle all the permit work as well. Staff worked hard, finished everything quickly and made sure the work site was clean as a whistle after they finished. Everyone was really friendly, from the receptionist on the phone, the staff and the people giving me estimates. It's been more than a year since I got my EV charger installed, and I haven't noticed any problems since then. Price-wise, I feel it was pretty fair especially considering how they made everything so convenient. All in all, they did everything well. I'd have no problems recommending them to others, and will likely go back to them when I need other things addressed in the house.

Everything was done very well and very quickly! Extremely competitive quote as well. When I initially reached out I wanted quotes from multiple businesses so I requested 3 businesses from yelp to come out. Of those quotes, the only one I got back in a timely manner was from Mario Castillo electric, one of the others came out and then just never go back to me with the quote, the other got back to me but over a week late (also came in super high), we're so happy we worked with these guys! Geo was excellent and super professional when he did the quote, the guys who came out to do the work were great as well. Very efficient and clean. Will for sure choose this business again in the future!

I didn't hear back from that other electrician so I sought help from Jeff Moore's. They were responsive and flexible options. They sent emails with prices and dates. They came 2 days after my initial call and came almost 30 minutes early to the appointment (but called 5 minutes out to ensure it was ok to come early). They came with 2 people and were professional. I trusted them as they seemed very knowledgeable and helped teach me about the different EV outlet options, what I could do with my electrical unit in the future, what caused my issue and what to expect. Payment was through Zelle. I loved that they diagnosed everything so quickly, fixed it quickly, and educated me through the process. I'd highly recommend them. The bad: I wish I had called them the first time for the initial installation! The interesting: The part was $30 and the service was $250.

We contracted with Penna for a full rewire, panel upgrade, and EV charger install for our 3br2ba…read moresingle family home in Torrance after initially reaching out to 8 electricians, and had a great experience overall. Todd (owner) was one of the few we brought out who actually listened to our goals and honored our vision rather than proposed either much more elaborate (expensive) or simplified (corner-cutting) projects that we weren't asking for. His quote came in right around where we expected for the scope of work. Carlos, Jesse, and the rest of their crew were great to work with. They respected our home, kept things clean, consistently used drop cloths, even vacuuming here and there to keep any mess at bay. They fished the vast majority of the new wires so well we had almost no holes to patch after all was said and done -- and any that did exist they also did rough patchwork that was easy for me to sand/texture/finish on my own afterward. Surgical precision that we weren't quite expecting but definitely appreciated. The scope of work was pretty large so a few small details temporarily fell through the cracks along the way (as they do), but Carlos checked in with us every morning to make sure he stayed aware of anything that was previously overlooked and/or any thoughts or tweaks we might want to express. His diligence led to us ultimately ending up with exactly what we wanted -- even as folks who had lots of questions and details to iron out along the way. He made us feel comfortable reaching out anytime for any reason. I'd happily work with Penna again for any electrical project, this team reflects what I always hope for (but rarely get) in a contractor. Cheers!
