Steps to Build Stairs with Composite Decking

Follow these steps to build safe and sturdy stairs for your composite decking:

Step 1: Measure the Height of Your Deck Rise

The first step is to measure the height from the deck to the ground. This measurement is the “rise” of your stairs. Divide this measurement by the desired number of steps to calculate the height of each step.

Step 2: Determine the Tread Height

The tread height is the distance between each step. The tread height will depend on the thickness of your composite decking and the number of stairs. The rise and tread height can be calculated using this formula: 2R + T = 25-26 inches.

Step 3: Cut the Stringers

Stringers are the support boards that run underneath the stairs and hold the treads and risers. Cut the stringers to length and angle them to fit the stair risers.

It is important to use pressure-treated lumber for the stringers to protect against rot and decay.

Step 4: Install the Stringers

Using a level, ensure that the stringers are properly aligned. Use concrete anchors and adhesive to secure the stringers to the deck.

Step 5: Install the Treads and Risers

Cut the treads and risers to length and install them on the stringers. Use screws to attach the treads to the stringers and adhesive to attach the risers.

Step 6: Install the Balusters and Railings

Install the balusters and railings, following the manufacturer’s instructions. Be sure to space the balusters evenly for safety.

Step 7: Finishing Touches

After the stairs are built, add finishing touches such as sanding and staining to enhance the look of your composite decking.
