I am replacing my deck. The footings and framing are contracted out but I will be doing the decking, railing and seats. I will be using a good grade treated lumber or cedar. This is a low level deck at about 18 inches off the ground. I am planning to use a herringbone design or similar(no zipper look). Is there a good way to insure that the ends of the boards that form the herringbone will not deform, raise up or twist over time?
