A deck repair of a leaning wooden deck is essential to provide needed stability and make sure that it does not come detached from your home. The deck over time due to weather or its normal use will need to be reinforced or repaired to restore it to its original working condition. This article will describe the materials, tools and steps required to repair a leaning wooden deck.

Step 1: Remove Deck Boards

Using a pry bar, remove the nails and screws that hold the deck boards in place. This should be done around the area where the deck is leaning. If necessary, depending on the extent to which the deck is leaning, you may need to remove all of the deck boards from the deck to reattach them.

Step 2: Replace the Joists

The joists underneath the deck should be checked for any damage or rotting. If the joists are the cause of the lean, remove the damaged area using the pry bar or by hammering the joist with a chisel to set it free.

With the damaged joists removed from the deck, replace them with new joists. A sealer preservative should be used on the joist when it is set in place. This will help reinforce the joist and make it last longer.

Step 3: Reinforce Deck Posts

Using a level, check the deck posts to see to what extent the deck is leaning. You will need to set a reinforcing post at an angle to the leaning deck to eliminate the lean. Attach the reinforced post to the leaning deck with the screw gun.

Check the deck boards again with the level once the angled board is set in place. Be sure that the lean has been eliminated completely before moving on to the next step of this process.

Step 4: Replace Deck Boards

With the deck posts properly set and level, attach the old deck board to the joists. Replace any damaged or warped deck boards with new deck boards. The boards should be set in place and secured to the joists using a screw gun (or a nailer if you prefer). Be sure that the deck boards are properly secured to the joists. Use the pressure sprayer to wash the deck once the deck boards are set in place.

Use a sealer preservative on the deck boards to prevent the deck boards from warping over time due to weather.

This should eliminate the lean in your deck. If the locking post does not eliminate the lean after the repair has been completed, consider taking the entire deck down and replacing it with a newer deck system.
