Drew has worked at several places where I was working. He corrected another electricians error in minutes. Very professional and more than fair pricing.
Cornerstone Electrical is a pleasure to work with and Drew is our electrician. He is honest, provides great value, outstanding work ethic (with emphasis on ethic). He looks out for his customers and we've been nothing but extremely pleased with his work. Small or large project, referral, emergency - call Cornerstone!
Drew did a fantastic electrical job in our home. His price was more than fair, and his work ethic is above and beyond. Not only was he professional, but he's very personable also. I would not hesitate to hire him for your electrical needs. Drew will be our electrician from now on.
