This problem is easily corrected with a little know-how!

  • Firstly, use one nail at each end of the decking to to secure it to the end joists.
  • If the deck board bows towards the last board laid and fastened, carefully force a chisel between the two boards and pry the bowed board outwards to the correct position, then nail or screw into place.
  • If the bow curves outwards, away from the last board, you will need to drive the chisel into the joist on the outside of the curve until it is in the correct position and then nail or screw into place.
