Step 3 · Install Treads

Place the first tread onto the bottom steps of the stringers. Ensure the tread is level and its front edge overhangs the riser slightly (typically 1 inch). Secure the tread by driving screws through the tread and into the stringer notches. Use at least two screws per stringer. Repeat this process for each subsequent tread, working your way up the stairs. Ensure each tread is level and consistently spaced from the one below.
