We added a double deck with a drainage system so that no water would penetrate through to the lower deck. Also added another deck for the hot tub.
Don't take our word for it...
John built a double deck for us overlooking the Chattanooga valley that was both breathtaking and structurally sound. We made several changes along the way which he was more than willing to accommodate. He was easy to communicate with and the guys onsite were all clean and professional.
