Carter from Castro came out quickly to do an estimate and was very responsive throughout the process. He gave us different options for how to do the job, and did not push the more expensive one. Once the job was booked, they were able to complete it very quickly. The electricians were professional and courteous, and did a fantastic job. Will definitely use Castro again for future jobs.

Peter was the technician that performed the work. He was on time, very professional, polite and immaculate. He explained the work he did. Very courteous, professional and will always use Astro electric for any electrical needs. Patricia was very professional and helpful. She returned all my calls and responded to my messages🙏

So thankful I called Castro Electrical Services for the job. The woman that answered the phone was so insightful! We had Carter to come in and do the estimate. He made sure to recommend what was needed first and then made suggestions. Luigi did a wonderful job on our heavy up. I know I will be reaching out to Carter again because of how helpful he was!

I used Castro Electric to update my old panels with new technology and install a Tesla charger. My job was also complicated by having a third panel for backup generator. They provided great service. I felt I was their number one priority even though they have many customers. They provided a good fair price and offered better technology than many of their competitors. I would use them again in a heartbeat

We needed our blown whole-house surge protector replaced, and, being new to the area, I called several highly-rated electricians in the area to both *find someone to replace it, and, hopefully, *find a great electrical company to call on as needed.

Castro's price was about on par with the others I called. However, on the phone, the representative I spoke with, Paul, answered my questions, listened to me, and was very polite and professional. It was the phone response I got that heavily leaned me toward Castro.

When the technician, Peter, came out to do the repair, he arrived in the 2-hour window provided. He was polite, respectful of my son (who was home at the time) and our home, and quick but thorough. He answered all of our questions and took the time to explain the work he had done, as well as the setup of the surge protector (as the home is new to us). He also helped with a minor other issue as a courtesy.

We will call Castro for our future electrical needs.
