2. Laying the Foundation

  • Lay the groundwork: On soil, opt for a weed barrier topped with 2-3 inches of gravel to help with drainage. For new building sites, choose the surface. Make sure it’s flat and firm for existing structures.
  • How to Install Joists: The joists are the foundation of your decking. Or for standard installations, using the same rule as with other types, space them 16 inches apart. Exact spacing is only a guideline. So, it is best to always refer to the manufacturer’s guidelines. Anchor the joists with joist hangers and check if they’re level.

3. Installing the deck boards.

  • Begin with the First Board: Position the initial composite deck board at the edge of the deck frame. Passage of air occurs beneath the boards. You can leave a small gap between the board and any adjacent structures. The gap helps absorb the boards’ expansion and contraction.
  • Secure the boards. Attach them to the joists using deck screws or hidden fasteners. A cleaner aesthetic, with less chance of scuffing the surface with hidden fasteners. To install screws at a 90-degree angle and keep them flush with the board.
  • Expansion and Drainage Spacing: Leave a 1/8- to 1/4-inch gap between boards for drainage and expansion. You can use spacers to maintain consistency.

4. Finishing Touches

  • Fit all the boards, then slice the overhanging edges. Cut them the same way you did with the circular saw.
  • Secure fascia boards across the edges of the deck. This hides the ends of the joists and gives the deck a smooth look.
  • Much of the time, you may have to look and dust. Look at your deck for sticking-out nails and uneven boards. With the installation, clean the deck to remove the garbage or dust.
