Replanking a Deck

December 13, 2018

If you are considering a revamp for your old wooden deck, but can't justify tearing down a perfectly good structural base, then don't! You may be able to save time and money by using AZEK Deck to simply resurface your existing deck structure instead of starting over from scratch. As long as your deck understructure is in good shape, it should be easy to replank the structure and get rid of those warped, splintered, and rotten wooden deck boards. Once the replanking is complete, you'll be able to skip the yearly painting and staining that your old deck required and enjoy more time in your outdoor space.


  • Faster installation
  • Cost-effective
  • No more painting, staining or sealing
  • Adds value to your home

For Best Results When Replanking Your Deck

  • Prior to installation, check to make sure all joists are level, structurally sound, and there are no nails or screws protruding.
  • Ensure that all joists are crowned correctly and are level across the top as AZEK Deck will conform to the surface contour of the substructure.
  • Proper joist spacing is required for proper installation. Joist spacing should not exceed 16” on center, or for a more rigid feel, 12” may be preferred.
  • Install solid wood blocking between each joist, placed every 4’ - 6’ within the structure to help reduce movement of the joists, excessive gapping, and give you a more uniform finished surface for your new AZEK Deck.
