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

ANNE CollinsANNE Collins

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.
