My wife and I just recently completed a massive home addition project with ST Evans as our GC. The project nearly doubled the size of our Clayton home, spanning three floors including adding onto the basement. Besides the high quality of the work, the attention to detail, and their professionalism, what we liked best about ST Evans is that they are good, honest people. What that means is they were very responsive, usually getting back to us about any concerns within the hour, at the latest later that day, and they stood by their work. We had heard a lot of horror stories about other general contractors essentially ghosting their customers or doing shoddy work. Our experience with ST Evans was exactly the opposite. We can't recommend them enough.
