Paul, the owner of Castro Electrical services is exceptionally customer oriented. His crew is professional. and does a very good job. Castro replaced ceiling lights after nearly 3 months without any issues. I am very pleased with the company and highly recommend.

I had a electrical panel relocation in my unit and was impressed with Rudy, everyone involved, and the whole process.

I was very impressed with your team, and especially Rudy who was so knowledgeable and provided the absolute best option with the least amount of disruption. He was professional, polite, patient and both he and Edgar worked very hard to accomplish this difficult task. They did not even take a break, and when it was all completed, they made sure to leave the space as clean as possible.

The insurance company for the condominium where I live required over 500 owners of individual apartments to replace their electrical boxes this year as a condition of renewing the condominium’s insurance policy next year. As part of the replacement, many owners had to move their electrical boxes in order to get a county permit for the replacement because the original electrical box location did not meet current electrical codes. We first called an electrical company who has done work for us in the past and they said that we would have to have kitchen cabinets taken off the wall before they could move and replace our electrical box. We then called Castro, who were recommended by many other residents of our building who had already had their electrical boxes moved and replaced, and they gave us an estimate that was significantly lower than the first contractor we talked to and that did not require us to remove cabinets from the wall. We signed a contract with Castro, they showed up as scheduled, ran the wires to move our electrical box location without removing any cabinets from the wall, and our new electrical box passed county permit inspection. Based upon this experience, I would definitely use Castro Electric again and I strongly recommend them to anyone who needs an electrician.
