James and Heather were enjoyable to work with from beginning to end! They are kind, professional, and courteous of their clients. We had a somewhat complex issue with the gate in our driveway that could have easily costed a pretty penny, but James was solution focused and worked creatively to keep costs down for our family. I was so impressed at what he came up with to fix our gate without replacing it, and yet it looked BRAND NEW by the end!
It's obvious James and his team don't just care about lining their own pockets, but care for PEOPLE. And we were truly blessed by that in our experience working with them. We will definitely call them first for any future projects on and around our whole property. I want to invest my money in a company like theirs who operates with passion and integrity!

After trying to replace the fence for over a year, my dad is relieved to finally have it done. The whole fence was replaced in less than 3 hours, it looks great & it’s sturdy. It’s just what my dad wanted. He’s very pleased with the work James did, & the dedication to the job that he brought. My dad is looking forward to having Cornerstone Construction help with some other jobs around his house.

James recently re-did one of our bathrooms and did an amazing job! He was very patient and helped guide us through our options and pick things that would keep us in budget. His workmanship is excellent and attention to detail was great! He was transparent throughout the entire process and we couldn't be happier with how everything turned out. Most importantly, he showed that he was trustworthy and we felt completely comfortable allowing him into our home to work independently. We couldn't recommend Cornerstone Construction enough!
