Staff was prompt, efficient and professional. They explained things that needed explanation and any follow-up questions. I would certainly recommend.

Tommy hurried to help me when I had multiple smoke detectors chirping even with new batteries. He carefully reviewed the situation and noted that this problem happens with old detectors. I confirmed that they were 10 years old. He gave the practical advice to replace them. Fortunately, he selected replacement detectors with lithium batteries. They will never need battery replacements! All of them were replaced efficiently and quickly. I’m thankful Cornerstone sent Tommy to do the job!

I recently had Cornerstone handle a number of electrical projects at my house, both indoor and outdoor, and I could not be happier with their work. The electricians were friendly, thorough, professional, and neat. They designed and installed outdoor and landscape lighting that elevated my home's curb appeal. Highly recommend Cornerstone Electrical Services!

I recently had Cornerstone Electric over to handle some electrical work at my home. While we did have a bit of a rough start initially, everything ended up working out just fine. The work was done professionally, and I want to give a special shout-out to Anthony, the technician, who was knowledgeable and courteous throughout. Later on, Vinny came back to hook up our spa, and he was just as much of a gentleman and a true professional. In the end, I’d definitely recommend Cornerstone Electric. They got everything done well, and we’re happy with the results!

Responsive professional company. Vinny was efficient and completed project on time and at fair cost to me. When I need even larger project like a Generac or whole house surge protector, I will call here first.
