Round up to get 15 steps.
Adding risers to deck stairs.
Houses of a certain age or with un improved basements feature open stairs containing only stringers and treads.
If you use the deck itself as the top riser as with this deck subtract one step.
The result will be the number of steps the staircase will need e g deck is 112 from the ground.
Nail on the second riser board and then screw on the two 2x6 bottom treads leaving a 1 4 in.
The fascia that covers their risers may be missing.
Add the risers and diy stair treads.
Adding led lights to deck stair risers install low voltage stair lights for safety and style.
Nail on the next riser then the next tread and so on to work your way to the top of the stairs.
This deck will have treads made of 5 4 inch x 6 inch decking planks two for each step making the run for each step the distance front to back about 11 inches.
Gap between the boards.
In addition to making your stairs safer covering the risers may be required by your local building code if you plan improvements to your cellar.
In our example 112 15 7 46 which means that the risers will be 7 46 high.
To calculate the actual rise height divide the height in inches by the number of stairs determined in the last step.
