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 can't say enough good things about Jesus and his son, Jesus. They arrived on time, were very…read moreprofessional, and did a fantastic job. We had an electrical issue that three other electricians couldn't figure out, but Jesus was able to diagnose and fix it. He even took the time to explain what was going on, which was so helpful. In addition to solving that issue, they installed permanent Christmas lights on two stories of our house, did some electrical changeouts on lights and fans, and added a GFCI outlet for our master toilet room. Everything looks amazing, and their work is top-notch. I highly recommend them for any electrical work! This version highlights their professionalism, expertise, and attention to detail while keeping it concise and clear.

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!

In my case, this meant installing a 60A breaker, wiring, and installation of a Tesla Universal Wall Connector to charge both our Rivian and Tesla EVs.

His two guys came on time and cleanly and efficiently installed the unit--loving my new 42 mile/hour charge speed for my Model S.

Jeremy…read morecame and looked at what we needed with no charge, sent us a quote that was honest and very reasonable. Believe me we have remodeled homes in NY, Altadena, San Marino, Pasadena, so we know what is reasonable. Jeremy arrived on time and to our surprise arrived with his father, a veteran electrician, and his son, now learning the business. They couldn't have been more efficient, neat and innovative. They replaced our old recessed halogen lights with state of the art LED. This was just not a replacement of the cans, since the old halogen lights were wired through some container that had to be opened and removed. Don''t ask me exactly, all I know is it took them time and effort. They even left us some halogen bulbs in case we needed to replace them in the back of the house. We will be changing those out for LED and will use Croff Electric. They were able to overcome a few jobs that had previously been done, before we owned the house, that had some questionable "fixes". They put in a new island electric outlet that took some doing, because there was little space between wine cooler and microwave. Everything was done to code. When they finished, I could hardly believe the care they took in cleaning up and putting things back in order, see Jeremy with a vacuum.

I received a text at 1:30 letting me know that a technician would arrive in about 30 minutes. Two technicians arrived almost exactly 30 minutes after that. They got right to work. They reconnected the wires, fixed a screw that they noticed was stripped, and rehung the chandelier. Then they tested to make sure that it worked. They were even kind enough to check a socket that I'd replaced myself to ensure that it was all good. Much appreciated and highly recommend!
