How To Build Cascading Deck Stairs

If you have a deck that is elevated from the ground, you will need stairs to access it. While traditional straight stairs work, cascading deck stairs can add a unique and stylish touch to your outdoor space. In this article, we will show you how to build cascading deck stairs.

Step 1: Gather Materials

Before you start building, you will need to gather materials. You will need pressure-treated lumber, concrete, screws, and a drill. Make sure you have all the necessary tools and materials before starting.

Step 2: Measure and Cut

Measure the height of your deck and determine how many stairs you will need. Cut the lumber to the appropriate length for each step. Make sure to double-check your measurements to ensure accuracy.

Step 3: Build the Base

Start by building the base of your cascading stairs. This will be the first step and will support the rest of the stairs. Use concrete to secure the base in place.

Step 4: Install the Stringers

The stringers are the angled pieces of wood that support the individual steps. Install the stringers onto the base using screws. Make sure they are level and secure.

Step 5: Install the Steps

Install each step onto the stringers using screws. Make sure they are evenly spaced and level. Repeat this step for each stair.

Step 6: Add Finishing Touches

Once all the steps are installed, add finishing touches such as railings and post caps. This will not only improve the aesthetic of your stairs but also add safety measures.
