Absolutely the best contractor I have dealt with. Very prompt and great communication. Employees are great and hard working. I had my garage demolished by them in record time and they left the site cleaner than it was before they started! Highly recommend and I’ll be hiring them for more projects in the future.

Johnathan was willing to come do an estimate and the work on the same day for me. It was a few small jobs that I couldn't get anyone else to do and he performed the work with no less care and attention than he would a bigger job. I appreciated that.

When we gutted our downstairs kitchen and living areas to the studs, our entire electric system had to be replaced. Because we were going to insulate with spray foam, JT at Cornerstone had to make sure our new sub panel and every plug, feed, and junction box was perfectly placed before the spray foam was applied. JT and his crew installed all the outlets and lights and appliances perfectly. His communication and many suggestions during the process ended with a dream kitchen. Below are “before” (brown tones) and “after” (gray tones) photos.

I went three days without electricity due to a broken wire main. I've tried to contact several electric companies and they were not able to come to my rescue because they were approaching the weekend and I could not wait until next week to get the power on. I decided to place a phone call to Cornerstone Electric and I was lucky enough to speak to JT. He was kind enough to collecet my information and after that, we met within a short period of time to assess the issue. It was one of the best phone calls that I have made during the course of the day. J.T helped resolving the issue in a professional manner and did an awesome job to restore the outage that I was trying to restore in three days. J.T is a very kind, friendly gentleman and a true professional. I highly recommand him to other clients cause he does excellent work. Thanks JT for a job well done!

I hired Cornerstone Construction to remodel my kitchen. I couldn't be happier. The guys were all very highly skilled and professional. My input was listened to and they made it happen at a fair price, in a timely manner and EXACTLY as I wanted. I even changed my mind mid construction a few times and they worked with me and adjusted the plan and presented various options. I got the kitchen I wanted- and even more. I highly recommend them if you are in the market for skilled, fair, professional contractors.

I would highly recommend Jonathan to anybody looking for a reliable, honest and professional electrician. His crew also deserves at least 5 stars due to the fact that they had to deal with a very irate and unreasonable tenant while they were doing their work. Jonathan showed up exactly as planned and completed the job earlier than expected even while being harassed for just doing his job. Left everything more orderly than when he arrived. I have recommended him before and would definitely recommend him again. Good JOB!!!

I have an old stone and block house that I was in the process of remodeling with another contractor. It was a bad experience with a lot of things left undone or not done properly and they never came back to finish or fix. JT and team came out for an estimate and just a few days later started the job. JT, Ed and Jay were a pleasure to work with. They know their stuff and got my house finished the right way in a reasonable amount of time. I truly appreciate their transparency at every step and would definitely recommend them when looking to hire a contractor who can do pretty much anything. There are a few things that still need to be done and I wouldn't think of calling anyone else. Nice work guys! I'm so happy I could cry right now! LOL So, hire Cornerstone! You will not be disappointed.
