He was punctual, very knowledgeable and respectful. And extremely fair on the price. Was in and out within an hour. Replaced breaker and rewired all the outlets. Diagnosed and fixed the problem extremely efficiently.

Sergio was quick to get a hold of, and he was there to replace a few blown outlets and was done within 30 minutes. I'd definitely call him again I I need any more electrical work.

Can't speak highly enough of this company and the owner Sergio! Unlike other contractors, he is responsive! When he couldn't answer my call, he would call me back within 24 hrs. He is knowledgeable, conscientious about his work, answered ALL my questions, even if it wasn't what he was hired to do. He went above and beyond! He was the best investment I made while building my ADU!

Half of my kitchen outlets blew out on Saturday of all days. I called Sergio, he gave me a quote and said he'd come in a couple hours. He immediately went to the circuit breaker, tested the one for the kitchen, replaced it and problem solved in less than 10 minutes. I highly recommend him.

It pains me to write this. I actually used Sergio quite a few times to do electrician work around the house and have always been satisfied with his work, suggestions, and care. Up until now. In Jan 2025, I asked him to upgrade my electrical panel as I had bought an EV. I knew this needed a permit through the city (or can cause issues with insurance if anything goes wrong). He quoted me a price with city permits and we started the job. They did a great job installing the panel and I paid for about half the job then, with the remaining to follow after the permit was procured. For the next year, Serio proceeded to drag me on, repeatedly promising over calls to begin the process. I had to consistently follow up and ask him to complete this and he kept telling me he would get it done. After 8-9 months of getting nowhere, I finally filed on my own and listed him as the builder. The city replied that his license number had expired so I reached out about that. His tone suddenly changed and he started to say that he didn't have the money to file for the permit or his business license in this city. He also said he undercharged me (not my issue) and I had to remind him that the amount I had ALREADY paid him was just part of it and he would get the remaining balance he would be collecting after this was resolved. He asked me to pay for his license and take it out of what I owed him. I was uncomfortable with that - why should I pay for his license to operate here? - especially since he had been less than forthcoming and was not following through on anything he was telling me he was going to do. He asked for one more month (October) to wait until his current job was finished and then he promised (for the thousandth time) that he would finish this up. I told him I really didn't want to have to follow up again, and he assured me (again) that I wouldn't have to. Well, sure enough, he did nothing and never reached out again. I tried following up with multiple texts/messages over the next few months and he is not responding to me at all anymore. It's now January 2026. As a result, I feel like I have no choice but to leave this negative review.

It's a shame because I really liked Sergio on a personal level as well, as we had talked about our beliefs and families. It's so sad to have the relationship dissolved over something like this.
