Highly recommended
This company was highly recommended to me and now I know why. They always returned a call promptly and were on time, they went above and beyond when it came to doing the job correctly, found and offered to fix previous wiring issues, were very professional and personable and were always willing to answer any questions I had. I have already asked them to come back and do some more work at the house. Thanks guys for a job well done.

Excellent Work!
We have had two significant jobs done by Cornerstone Electrical Services. Josh and his partner were very good to work with, completely honest, very conscientious, reliable, and very responsive to our needs . Their pricing is reasonable and they take great pride in their work, which is a rarity these days. Cornerstone installed a generator and panel and helped resolve a generator issue which they were not responsible for. We had issues with our old electrical panel, significant issues from years past and Cornerstone very professionally took care of all the issues in a timely manner. I cannot say enough about Josh and his partner and Cornerstone Electrical Services. Excellent in every way.
