Overview: The weak deck problem and solutions
Now for the good news. Most of the fixes are quick, inexpensive and easy. Home centers and lumberyards carry the tools and materials you'll need. Or visit strongtie.com to find local stores that stock anchors, post bases and connectors.
In this article, we'll show you the warning signs of a dangerous deck—and how to fix the problems. If you're still not sure whether your deck is safe, have it inspected by your local building inspector.
Problem 1: No lag screws in ledger board
Starting at one end of the ledger board, drill two 1/4-in. pilot holes. Offset the holes so the top isn't aligned with the bottom hole. Then drive the lag screws (with washers) using a drill and an impact socket (you'll need a socket adapter that fits in your drill). Don't countersink the screws—that only weakens the ledger board.
