When the decking gets tough, the tough get decking. And it all starts with understanding your options. TimberTech® makes it easy to understand the value of TimberTech versus wood.

Pressure Treated Wood

Pressure Treated Wood

Although traditional lumber still attracts many home owners, the appeal often fades as quickly as the wood does. Without frequent and necessary maintenance, pressure treated wood decks can splinter, warp or cup—and this can happen within the first few years. In the long run, wood decks can become an expensive and time consuming addition to a home.

TimberTech Wood Composite Deck

Wood Composite

TimberTech: ReliaBoard®, TwinFinish®, DockSider Collections

TimberTech’s composite decking is made of plastic and wood fibers, making it more resistant to the elements than traditional wood. Composite boards are splinter-free, and upkeep is low stress; there’s no need to seal or stain your deck for protection annually like with pressure treated wood. A balance of affordability and aesthetics, these practical, low-maintenance decks are a great option.

TimberTech Capped Wood Composite Deck

Capped Wood Composite

TimberTech: Legacy, Terrain, Tropical Collections

With the look and feel of real lumber, capped composite decking offers the charm of traditional wood without the hassle of frequent maintenance. TimberTech’s composite core is made of plastic and wood fibers and surrounded with a protective cap on all four sides and every groove. While most manufacturers cut corners and neglect the bottom of the deck board and groove, TimberTech goes the extra mile, making your deck strong enough to resist scratches, stains, and fading. It’s a high-end look with added strength and a competitive price point.

TimberTech Deck Replanking

Your Deck

Save the Understructure,
Change the Surface

Save time and money using TimberTech® composite decking to re-plank your existing deck instead of starting from scratch. When an old wooden deck becomes warped, splintered, and rotten, it’s easy to re-plank using TimberTech composite or capped composite decking. Replacing wood decking with TimberTech decking gives you more time to enjoy your outdoor space as yearly staining and painting will no longer be necessary. And, as for rotting and splinters, well, they too will be a thing of the past.


  • 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.
