Building deck steps without stringers can be accomplished using the "box step" method. This approach involves constructing a series of wooden frames, or boxes, that serve as the steps and support the deck's weight. Here's a step-by-step guide to building deck steps without stringers:
Tools and Materials You'll Need:
- Pressure-treated lumber (2x6 or 2x8)
- Circular saw or handsaw
- Power drill
- Deck screws
- Measuring tape
- Level
- Gravel or crushed stone
- Concrete blocks (optional, for additional support)
- Decking boards (for the step treads)
Step 1: Measure and Plan
- Determine the desired height and width of your steps. Measure the total height from the ground to the top of the deck and the desired width of each step. Divide the total height by the height of each step to determine the number of steps needed.
Step 2: Cut Lumber
- Cut pressure-treated lumber to create the boxes for each step. The length of each piece should match the width of the steps you want, and the height should match the height of each step you calculated.
Step 3: Assemble the Boxes
- Lay the cut lumber pieces flat on the ground to form the step frames. Arrange them in a stair-like pattern, ensuring they are level and aligning the top and bottom edges. Use a power drill and deck screws to secure the pieces together at the corners.
Step 4: Prepare the Ground
- Clear the area where the steps will be installed and level the ground. You may want to add a layer of gravel or crushed stone to create a stable base for the step frames.
Step 5: Install the Step Frames
- Place the assembled step frames on the prepared ground. Ensure they are level and stable. You may need to adjust the ground or add concrete blocks under the frames for additional support.
Step 6: Attach Step Treads
- Once the step frames are securely in place, add the step treads. These are the horizontal pieces that you'll step on. You can use pressure-treated decking boards for this purpose. Attach the treads to the top of each step frame using deck screws.
Step 7: Add Handrails (Optional)
- If desired, you can install handrails on the sides of the steps for added safety and support. Use pressure-treated lumber and secure the handrails to the deck and the top step using deck screws.
Step 8: Finish and Maintain
- Apply a weather-resistant finish to protect the wood from the elements. Regularly inspect and maintain your deck steps to ensure they remain safe and sturdy.
Keep in mind that while the box step method can work well for shorter sets of steps, it may not be suitable for higher deck elevations. For more complex and higher decks, it's generally best to use traditional stringers for increased structural integrity and safety. If you're unsure about your project's complexity or safety considerations, consult with a professional builder or contractor.
