(See below for a shopping list and tools.) SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse Tom Silva and Kevin O'Connor replaced several wooden 4x4 posts that were supporting an exterior deck. The posts, which were not pressure-treated, sat directly on top of concrete piers. They had completely rotted at the bottom due to moisture wicking up through the concrete. Before removing the old posts, Tom & Kevin installed temporary bracing using 2x4's and a sledge hammer. With the deck temporarily supported, they removed the old posts and installed new pressure-treated ones. They also installed a galvanized steel post base at the bottom of each post, eliminating direct contact with the concrete piers.
