At NS Constructions, we understand that building the perfect deck stairs can seem like a daunting task.
Many homeowners consider outsourcing this part of their deck project to professionals due to its complexity.
However, with the right guidance and expertise, you can successfully tackle this challenge.
In this comprehensive guide, we’ll walk you through the process of building deck stairs, from initial measurements to final assembly.
Understanding the Basics
Before diving into the construction process, it’s crucial to grasp the fundamentals of stair design. The key elements are:
- Rise: The vertical height between steps
- Run: The horizontal depth of each step
- Stringers: The diagonal boards that support the steps
Getting these measurements right from the start is essential for a safe and comfortable staircase.
Materials and Tools Needed
To build your deck stairs, you’ll need the following materials and tools:
Materials:
– Pressure-treated lumber for stringers, treads, and risers
– Deck screws and nails (suitable for treated lumber)
Tools:
– Measuring tape
– Chalk line
– Circular saw
– Handsaw
– Drill/driver
– Framing square with stair gauges
– Level
– Safety glasses
– Sawhorses
– Pencil
Having these items ready before you start will make the process smoother and more efficient.
Step-by-Step Guide to Building Deck Stairs
Step 1: Measure the Total Rise
- Visualize a stair slope at about a 40-degree angle.
- Place a straight board from the deck edge to the estimated landing point.
- Use a level to ensure the board is flat.
- Measure from the board’s end to the ground – this is your total rise (let’s call it “X”).
Step 2: Calculate the Number of Risers
- Divide X by 7 inches (average step height).
- Round to the nearest whole number for the number of risers.
- Ensure the riser height is between 6-1/2 to 8 inches.
Step 3: Determine Treads and Total Run
- Subtract 1 from the number of risers to get the number of treads.
- Multiply treads by 10-1/4 inches (width for two 2x6s) for the total run.
Step 4: Layout the Stringers
- Use a framing square with stair gauges to mark risers and treads on a 2×12 board.
- Remember: The top tread is 3/4 inch shorter, and the bottom riser is 1-1/2 inches shorter.
Step 5: Cut the Stringers
- Use a circular saw to cut along marked lines, stopping just before the end of each notch.
- Finish cuts with a handsaw to avoid weakening the wood.
- Use the first stringer as a template for others.
Step 6: Prepare the Landing and Attach Stringers
- Create a solid landing using concrete, pavers, or a leveled wooden frame.
- Secure stringers to the deck with 3-inch deck screws.
Step 7: Install Risers and Treads
- Start from the bottom, attaching the first riser with galvanized nails.
- Install the first tread, leaving a 1/4-inch gap for drainage.
- Continue alternating risers and treads to the top.
Step 8: Ensure Proper Alignment
- Use a level and tape measure to check evenness and alignment.
- Make adjustments as necessary.
Step 9: Add Skirt Boards and Supports
- Attach skirt boards to the deck’s rim joist.
- Add 2×6 supports across stringers for extra stability.
Step 10: Final Safety Check
- Install handrails if required (typically for stairs with four or more steps).
- Test the stability of the stairs.
- Ensure all screws are tight and there are no protruding nails or rough edges.
Safety Considerations
At NS Constructions, we prioritize safety in all our projects. When building deck stairs, keep these crucial points in mind:
- Proper Handrail Installation: Install sturdy handrails on both sides for stairs with four or more steps.
- Code Compliance: Familiarize yourself with local building codes before starting construction.
- Anti-Slip Measures: Consider adding anti-slip treatments to stair treads for improved safety.
Regular Maintenance
To ensure the longevity and safety of your deck stairs:
- Regularly inspect for loose boards or protruding nails.
- Check for signs of rot or insect damage.
- Clean and reseal the wood as needed to protect against weathering.
