 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
