David was my electrician for my remodel and he did an amazing job.
When the inspector came, he saw how perfect everything looked in the first room he didn't even look at the rest.
He does good work

Every time I call David with a new electrical project he delivers. Usually has time in the schedule to get to me quickly. He always does a very detailed professional looking job. Honestly I can't think of anything to complain about. Definitely recommend using Cornerstone Power for any of your electrical needs!

Got here on time and finished on budget. David did such a wonderful job. Made my basement feel like a whole new space.
