Heres the deal. We recently bought a small cottage by a lake. It has a 12x24 deck on the back which looks bad. Not only are the decking boards quite rotten, but the outside edge (away from the house) looks to have settled arout 4 inches. Maybe it was built that way??? The uprights look good, as well as the stringers. I'm wondering if I can just take the deck boards off, and somehow get the deck back to level. Help!
