How to Replace a Deck Joist Hanger

  1. Remove the fallen joist.
  2. Remove the remaining corroded parts of the hanger.
  3. Remove the nails from the deck by removing them from underneath.
  4. Turn the joists 180 degrees so the old nail holes face the ground.
  5. Use a scrap of wood to support the joist.
  6. Screw a few screws in the joist until the hanger is attached.
  7. The hanger should be nailed into place.
  8. Nathan only used an angle bracket on the side opposite the ledger board because there was already a ledge to support the joists.
