Mario Castillo and his team did an excellent job on our electrical panel upgrade along with several smaller projects, including installing miscellaneous outlets and a bathroom fan. From start to finish, the work was professional, efficient, and clearly done with care.Salvador and Kevin were especially great to work with. They were thoughtful and respectful of the historic nature of my 100-year-old home, taking extra care to preserve its character while updating the electrical systems. They communicated clearly, kept the work area tidy, and approached every detail with professionalism.It’s not always easy finding electricians who understand older homes, but this team really does. I highly recommend Mario Castillo and his crew for anyone needing electrical work, especially in historic properties.
Had intermittent power on some outlets, and just occurs randomly when power is available and not. Checked the circuit breakers and none were popping every time juice was off. Made appt with Mario Castillo Electric and Vic showed up on time. I told him the situation and he checked the affected outlets and all the circuit breakers. Isolated it to a circuit breaker and replaced it. Back to normal again. I would recommend this company amd Vic.. Vic was methodical, quick, and shared his knowledge on what's he was doing. Great job!
Every part of the experience working with Mario Castillo Electric impressed me. Victor came out and gave us a detailed quote. Gabriel and Salvador performed the work and did a great job. The price was very reasonable, communication was good throughout the process, and they did excellent work. They’ve been way more on top of things than other companies I’ve worked with and they will be the first people I call from now on.
