For a while now we’ve noticed the deck has been sagging near the house. When you walk in that area there is a noticeable bounce and my best guess was the joists were no longer attached. So this weekend I pulled the decking in that area off and found my guess was correct. I’m no builder but where are the hangers on the header board ? Maybe that is optional depending on materials, size, etc …. not sure. None the less will need to add this to the weekend “to do” list before something bad happens.
