Install New Risers and Treads

What happens in this clip

With the structural supports in place, install the new risers and treads. The new risers will not necessarily fit into the dadoed slots in the stringer, or it may be too difficult to install them if they do. Cut each riser and tread to fit precisely into its position. You can start the installation from either the bottom or the top of the stairway, whichever is more convenient for your workflow. Fasten the risers and treads securely using screws or nails. Pay attention to the squareness of the cuts, especially on sides that will be visible, as some sides might not be perfectly square depending on the existing stringer. The level of importance for precise cuts will depend on the desired finish and visibility of the stairs (e.g., if they will be carpeted).

Goal: Fit and secure new risers and treads into the repaired stair structure.

About the full video

This DIY project provides detailed instructions for repairing or reinforcing stairs with housed (dadoed) stringers, which are common in older homes, by addressing structural problems like gaps between treads, risers, and stringers. The project outlines methods for removing damaged components, accessing the underside of the stairs, and installing new support structures or replacing the treads and risers.

Step 5 of 8: Cut and Attach Risers (Optional)

If desired, measure and cut pieces of wood to fit vertically between each tread. These are the risers. Attach them securely to the front of each tread support on the stringer, using screws or nails. Ensure they are level and evenly spaced.
