Step 3 · Install New Treads and Risers
Position the new risers first, securing them to the stringers and sub-tread or nosing of the tread below. Then, install the new treads. Ensure the front edge of the tread (the nosing) extends slightly past the riser. Treads are typically secured through the stringers from underneath with screws or nails, and also by adhering them to the sub-tread and riser. Use construction adhesive for extra strength. Make sure each tread is level and firmly attached. If using pre-finished treads, be careful not to scratch them during installation.
