Measure the exact width of the vertical openings between each step tread. Using a circular saw, cut pieces of 1x8 treated lumber to these precise dimensions. These pieces will serve as the risers, covering the vertical gaps and completing the enclosed look of the steps. Fit each cut 1x8 piece into its respective vertical opening, ensuring it is flush with the underside of the step tread above it and the front of the step tread below it. Securely nail each riser board into the stringers and the underside of the treads using galvanized nails or deck screws.
