Building stairs outside is a great way to improve the accessibility and curb appeal of your home. However, it can be a daunting task if you’ve never done it before. That’s why we’ve put together this guide to help you build stairs outside like a pro.
The first step is to plan your stairs. You’ll need to decide where you want your stairs to go, how wide you want them to be, and how many steps you need. Once you have a plan, you can start gathering the materials you need. You can buy pre-made stairs, which are the easiest option, or you can build your stairs from scratch. If you decide to build your stairs from scratch, you’ll need to purchase lumber, concrete, and other materials. Additionally, you’ll need some basic tools, such as a saw, a drill, and a level.
Once you have your materials and tools, you can start building your stairs. The first step is to build the stringers. These are the slanted supports that form the sides of the stairs. Once the stringers are in place, you can start attaching the treads. These are the horizontal boards that you step on when you walk up the stairs. Finally, you can add risers, which are the vertical boards that fill in the space between the treads.
Materials and Tools
Materials
The following materials are required to build stairs outside:
- Pressure-treated lumber for the stringers, treads, and risers
- Concrete or gravel for the base
- Metal brackets or bolts to secure the stringers to the ground
- Nails or screws to secure the treads and risers to the stringers
- Caulk or weatherstripping to seal any gaps
Tools
The following tools are required to build stairs outside:
- Circular saw or miter saw
- Drill
- Level
- Hammer or nail gun
- Caulk gun
- Trenching shovel (if necessary)

| Miter saw | Secure the workpiece properly. Use a push stick to feed the workpiece through the blade. |
| Drill | Wear gloves to protect your hands from splinters. Clamp the workpiece to prevent it from moving. |
Excavation and Foundation
Excavation
Begin by marking the staircase’s location and outline. Excavate the area to a depth of 12-18 inches below the finished grade, ensuring the width and length are sufficient to accommodate the stairs, landings, and any required supports.
Creating the Form
Construct forms for the concrete footings and risers. For footings, use 2×4 lumber or pre-made concrete forms, extending them beyond the excavated area by several inches. For risers, use plywood or sturdy boards cut to the desired height of each step.
Placing Reinforcements
Reinforce the footings and risers with rebar. Use #4 or #5 rebar spaced at 12-18 inches on center. Place the rebar in the bottom of the footings and in the center of the risers, ensuring the bars extend into the footings.
Concrete Pouring
Pour concrete into the forms, filling them up to the top. Smooth out the concrete surface with a trowel and level it using a screed. Allow the concrete to cure for several days before removing the forms.
Installing Stringers
Once the concrete has cured, install stringers, which are the supporting beams that connect the treads to the risers. Stringers should be made of pressure-treated lumber or metal. Space them evenly apart to support the treads and provide stability.
Tread and Riser Installation
Attach the treads and risers to the stringers using screws or nails. Ensure the treads are level and the risers are plumb. Secure the treads and risers firmly to prevent any movement or shifting.
Backfill and Compaction
Backfill the excavated area around the stairs with compacted soil or gravel. Ensure the backfill is properly compacted to support the stairs and prevent settling.
Table: Recommended Rebar Spacing for Staircase Construction
| Element | Rebar Spacing |
|---|---|
| Footings | 12-18 inches on center |
| Risers | 12-18 inches on center |
Building the Stringers
Stringers are the backbone of your stairs, providing support for the treads and risers. To build them, you’ll need pressure-treated lumber and a saw.
- Cut the stringers to the desired length. The length will depend on the height and width of your stairs.
- Mark the locations of the treads and risers on the stringers. The treads should be spaced evenly apart, and the risers should be consistent in height.
- Cut notches into the stringers for the treads and risers. The notches should be deep enough to fit the treads and risers snugly.
- Attach the treads and risers to the stringers using screws or nails. Be sure to predrill the holes to prevent the wood from splitting.
Tips for Building Stringers
Here are a few tips for building stringers:
- Use high-quality pressure-treated lumber. This will help to prevent rot and decay.
- Make sure the stringers are level and parallel to each other. This will ensure that the stairs are safe and stable.
- Cut the notches for the treads and risers carefully. The treads and risers should fit snugly into the notches.
- Secure the treads and risers to the stringers with screws or nails. Predrill the holes to prevent the wood from splitting.
| Stringer Length | Number of Treads | Tread Height | Riser Height |
|---|---|---|---|
| 10 feet | 11 | 9 inches | 7 inches |
| 12 feet | 13 | 9 inches | 7 inches |
| 14 feet | 15 | 9 inches | 7 inches |
Installing the Risers and Treads
Step 1: Measure and Cut the Risers
Measure the height of the individual steps. Cut the risers to this height using a circular saw. Ensure the cuts are clean and square for proper alignment.
Step 2: Attach the Risers
Place the first riser at the bottom of the stringers. Use deck screws or galvanized nails to secure it to the stringers. Continue attaching the remaining risers, ensuring they are aligned vertically.
Step 3: Measure and Cut the Treads
Measure the length of each tread, ensuring they extend slightly beyond the risers. Cut the treads to size using a circular saw.
Step 4: Install the Treads
Position the first tread on top of the first riser. Use screws or nails to secure it to the tread hangers on the stringers. Continue installing the remaining treads, ensuring they overlap the risers by about 1 inch.
Step 5: Secure the Treads and Risers
After all the treads and risers are in place, reinforce their connection with additional screws or nails. Ensure the fasteners are countersunk below the surface for a clean and tamper-proof finish. The table below summarizes the steps for securing the treads and risers:
| Step | Action |
|---|---|
| 1 | Drill pilot holes in the treads and risers. |
| 2 | Insert screws or nails into the pilot holes. |
| 3 | Countersink the screws or nails below the surface. |
