Screwdriver

How to Do It

Walk the full perimeter of the deck and visually scan the decking, railings, posts, and ledger board before touching anything.
Push and pull on every railing section and post. Any movement indicates a loose connection that needs repair.
Probe any discolored, soft-looking, or weathered decking boards with a screwdriver. Wood that gives easily or crumbles has rot and should be replaced.
Inspect the ledger board where the deck attaches to the house. Look for gaps between the ledger and the house, rusted fasteners, or staining that suggests water infiltration.
Note every problem you find. Prioritize loose railings and ledger issues, as these are the most common causes of deck failure.
