A Leaky Deck Problem: The posts on the deck above the living space had not been properly flashed when it was built and the windows weren't properly installed either. New plywood decking was installed after the railing and posts were removed. In the 'after' pictures, you can see the posts are flashed and counter-flashed. The windows were removed and reinstalled with properly attached nailing fins, sealing tape and head flashing. Dry rot was found and removed in the deck, in the walls above both windows and below one window. After re-siding, caulking, painting and cleanup, you can hardly tell we were there. Except there's no more water on the family room floor!
