We had to have a heavy up at one of our condos. I can't Thank Castro enough ! Patricia who sets up everything was absolutely amazing and helpful! And Carter who kept me informed on the whole process and updates was just so professional and kept me updated on the job and completion when it was passed for inspection. The whole process was easy and affordable. I got quotes from two other companies and were just much more pricy. I can't thank this company and team enough and will definitely use them again. excellent job! thanks again!

Have had Castro out several times for troubleshooting as well as general electrical work (including outdoor receptacle and fan installation). I have been totally blown away by everyone’s professionalism, personable affect, and attention to detail. Communication is great. Prices appear very reasonable. They were able to diagnose a tricky safety hazard and remedy the situation thoroughly. I cannot recommend them enough!

Specifically I want to say a special thanks to Peter for his diagnostic work and attention to detail. He is also incredibly kind and clearly loves his work and the people he helps. He’s very smart and I trust him fully

Outstanding service and reasonable price. After getting a different estimate that offered a more destructive solution at twice the price from another vendor, I happily hired Castro. Everyone from the person who arranged the work to the electricians, and owner were professional and friendly. Very customer focused. Great communication.

It’s a pleasure to work with a service provider that knows how to get customer service right! Castro Electrical worked with me to get a critical electrical upgrade completed on a schedule that was important to me. Even if that meant inserting a job into an already full calendar, modifying the estimate and job specifications per my requirements, or having Peter and Carter (both managers) themselves come out and do the work. This team, together with their boss and owner Paul really differentiates themselves with their flexibility and customer focus while also being excellent electricians who know the job and how to do it with high quality!

I reached out to Castro Electrical Services (CES) when I was having some acute electrical issues in my home (Feb 2024). This is a local, family-owned business- something that really resonates with me, so I wanted to give them a chance and they didn't let me down! CES was responsive and able to help me in a timeframe that was very helpful! I submitted a request for service online late at night when my issues started (they have an emergency number, but I didn't need to use that) and I received a text that night asking me to send any more details, pics, etc about my problem via text. We communicated more by text the following day and I was able to speak with Paul Castro so I could understand the process, possible costs and to be sure I had communicated my concerns through text clearly. On the day of service, the service tech (Shawn) arrived promptly, was very professional, did repairs/work very efficiently and quickly and explained everything very clearly.
In my naivete, there were things that I thought would need to be done, but he gave me an honest assessment and only did what was necessary. Another company might have pushed through and taken advantage of my ignorance just to make more money, even if the work wasn't necessary. In the end, some of the work involved replacing light switch, wall outlet, and light fixture. Everything was done at a very reasonable price, too! Honestly, this was the best experience I've had in ages. I can't recommend them highly enough. I'm so lucky CES is in my area. I plan to use them for all of my electrical needs!

I requested two projects from Castro at a great value, and let me tell you, I'm positive I was a big nuisance in the mix of it all. My goal was to get a...

For lots of reasons I appreciated Castro Electrical Services, but one thing I found unique is that they could provide an hourly rate (which I thought was...
