 Trustindex verifies that the original source of the review is Google. The Castro team was professional, prompt and very easy to work with.  I had called for service after losing power in a portion of my home and being unable to fix myself. They came the next morning, after determining an after hours service was not necessary, and they were able to resolve the issue quickly. They very clearly answered my questions and explained what may have caused this. I would reach out to them for any electrical needs in the future

 Trustindex verifies that the original source of the review is Google. Castro Electric is a very professional business. Rene was very courteous and clear in communicating the scope of the work, and Taylor, the electrician who performed the work, was very pleasant, affable and professional. From the moment you contact Castro Electric you will deal with Alba who will assist you very efficiently in communicating messages, making payments, etc. Overall, I highly recommend Castro Electric for a seamless and easy relationship.
