“We could not be happier with the way our deck turned out! Beginning with Ron from sales, Sarah in color and design, and Sammy, our foreman and his crew, everything was perfect! Planning, design, and execution was spot on and brought our dream deck to life! Sammy and his crew were so professional and delightful to work with. He communicated with me daily on questions and preferences, and always let me know who was going to be at the house on what days. The craftsmanship was impeccable and the project was completed on time! We will recommend Keystone to everyone we know!”
