Unfortunately, when it comes to wood decking, poor maintenance can also pose a safety hazard. Dry rot, weakened ledger connections and failing footings can all contribute to deck collapse. Not to get all doom and gloom on you, but deck collapses have injured 900 people and killed 20 in the last 15 years, and decking professionals estimate that half of the decks in the United States are either poorly constructed or in a state of advanced decay. One hard winter may be all that is needed to push some of these aging decks over the edge. [ . . . ]
