We did a total remodel of the first floor of our home. Cornerstone Electric did all of the electric updating and performed an excellent job of adding a beautiful lighting ambiance to our remodel. In addition, there were many electrical problems related to an older home that needed attention. These electricians corrected them easily without any issues. The work was done with total professionalism and promptness. They were very easy to have in my home and did neat and clean work. I would highly recommend Cornerstone Electrical Services.

The team at Cornerstone impressed us the first time we hired them for our new home. Since the successful completion of our initial project we have used them several more times for large and small electrical projects in our home with complete confidence. They are knowledgeable and reliable. They always leave the work site clean, and free of any sign of a project had been completed. I feel safe knowing cornerstone was responsible for the electrical work in my home and would highly recommend them.
