How to add stairs to your existing deck.
Building stairs from a deck can seem like a daunting task, but with the right tools, materials, and a step-by-step guide, you can confidently tackle this project. In this guide, we’ll walk you through everything you need to know about how to build stairs from a deck, ensuring your project meets building codes and results in a safe, sturdy staircase.
Step 1: Planning and Preparation
Measuring the Total Rise and Run
Before you begin building stairs, it’s essential to measure the total rise and run accurately. The total rise is the vertical height from the top of the deck to the ground, and the total run is the horizontal distance the stairs will cover.
- Measure the Total Rise: Use a measuring tape to determine the height from the top of the deck to the ground.
- Number of Risers: Divide the total rise by the desired rise of each step. This is usually around 7 inches) This will give you the number of risers.
- Total Run Calculations: Multiply the number of risers by the desired tread depth. This is typically 10 inches.
Gathering Materials and Tools
You will need the following materials and tools:
- Lumber (for stair stringers, treads, and risers)
- Concrete landing pad materials
- Decking boards
- Framing square
- Measuring tape
- Circular saw
- Drill
- Screws
- Level
- Stair railing materials
Code Requirements and Safety
Before you start cutting, familiarize yourself with local building codes to ensure your stairs meet all safety requirements. Generally, deck stairs should be at least 36 inches wide, with consistent rise and run dimensions.
Step 2: Building the Stair Stringers
Mark and Cut the Stringers
- Use a Framing Square: Mark the top of the stringer with a framing square to establish the rise and run of each step.
- Cut the Stringers: Carefully cut along your marks with a circular saw. You will need three stringers for a standard deck stair.
Attach the Stringers to the Deck
- Secure the Stringers: Attach the stringers to the deck frame using screws or metal hangers. Ensure they are level and evenly spaced.
- Install the Concrete Landing Pad: At the base of the stairs, prepare a concrete landing pad to provide a stable foundation for the stringers.
Step 3: Installing Treads and Risers
Attach the Treads
- Cut the Treads: Measure and cut the decking boards to fit the width of the stairs.
- Secure the Treads: Attach the treads to the stringers using screws. Ensure each tread is level before securing it.
Install the Risers
- Cut the Risers: Measure and cut the risers to fit between the treads.
- Secure the Risers: Attach the risers to the stringers and treads with screws, ensuring a tight fit.
Step 4: Finishing Touches
Install the Stair Railing
- Measure and Cut the Posts: Measure and cut posts for the stair railing. Attach them to the stringers and deck frame.
- Attach the Railing: Secure the railing to the posts, ensuring it is level and sturdy.
Final Inspection
- Check for Stability: Ensure all parts of the stairs are secure and stable.
- Verify Compliance: Double-check that the stairs meet local building codes and safety requirements.
