We need to get started on our porch stairs. Because of the raised house height, we are going to come down 6 steps onto a small 6 x 8 deck, then exit with two side steps off of the deck. The top steps will be wide (almost 8 ft wide). This is on the north side of the house, so it will slime up in the rainy season. The problem was so bad with the old steps that the last time I painted them I added a little sand to the paint. Otherwise we couldn't use them safely when they were wet, which was most of the winter. This is an old craftsman style house. We'll be running bevel sided wing walls along the steps. We don't want the California redwood porch look, nor exposed pressure treated lumber. I've thought of wrapping the 4x4 PT posts in cedar and maybe using that for the risers. What are our wood options for stair tread? What would you suggest for the deck?
