Positioning and Securing the Stringers
Stringers are the inclined members that support the stair treads. They must be properly positioned and secured to ensure the stairs are safe and stable. Here are detailed steps for positioning and securing the stringers:
1. Determine Stringer Placement
Mark the location of the stringers on the deck and the landing or ground level. Use a level to ensure they are plumb and level. The spacing between the stringers should be equal.
2. Cut Stringers to Length
Measure the distance between the deck and the landing or ground level. Cut the stringers to this length.
3. Attach Stringers to the Deck
Place the stringers against the deck frame. Use deck screws or bolts to secure them. Start at the top of the stairs and work your way down. Make sure the stringers are level and plumb.
4. Secure Stringers to the Landing or Ground
Extend the stringers beyond the deck to reach the landing or ground level. The overhang should be at least 1 foot. Use concrete anchors or stakes to secure the stringers to the ground.
| Method | Description |
|---|---|
| Concrete Anchors | Drill holes into the concrete, insert concrete anchors, and tighten the bolts to secure the stringers. |
| Ground Stakes | Drive ground stakes into the soil and attach the stringers to the stakes using lag bolts. |
Remember to check the plumb and level of the stringers throughout the installation process. Properly positioned and secured stringers will provide a solid foundation for the stairs.
Installing the Risers
Risers connect the treads to create the vertical height of the stairs. It is essential to measure and cut the risers accurately to ensure a level and stable staircase.
Step 1: Measure and Cut the Risers
Measure the height from the bottom of one tread to the top of the next and add 1/4 inch to allow for building tolerances. Cut the risers to this length using a circular saw or a miter saw.
Step 2: Position the Risers
Place the first riser against the inside edge of the stringer and align it with the top of the bottom tread. Secure it using two 3-inch deck screws. Ensure the riser is plumb before securing it.
Step 3: Attach the Risers to the Treads
Align the second riser on the stringer and secure it to the top of the first tread using four 2 1/2-inch deck screws. Repeat this process for each remaining riser.
Step 4: Finishing the Risers
Once all the risers are installed, countersink the screws using a drill and a countersink bit. Fill the screw holes with wood filler and sand them smooth once dry.
Step 5: Check the Level
Use a level to check the horizontality of each tread and the verticality of each riser. Make any necessary adjustments by shimming or removing material as needed.
Step 6: Install the Skirt Boards (Optional)
To give the staircase a finished look, you can install skirt boards along the sides of the risers. Measure and cut the skirt boards to the length of the risers, then secure them in place using 1 5/8-inch deck screws.
| Material | Dimensions |
|---|---|
| Risers | 1×12 |
| Deck screws | 3-inch and 2 1/2-inch |
| Skirt boards | 1×10 |
