How to Install New Stair Treads and Risers: A Step-by-Step Guide
Brief Summary
Installing new stair treads and risers involves careful preparation, precise measurements, and proper fastening techniques. The general process includes removing existing treads and risers, preparing the stringers, measuring and cutting the new components, and then securely attaching them using construction adhesive and fasteners.

Preparation is Key
- Safety First: Before you begin, ensure the work area is clear of any obstacles or tripping hazards. Use a sturdy ladder or scaffolding for safe access to higher steps. Wear appropriate safety gear, including gloves and eye protection.
- Remove Existing Treads and Risers: If replacing old treads and risers, carefully pry them off using a pry bar and hammer. Take care not to damage the stringers (the supporting boards) during removal.
- Clean and Inspect: Thoroughly clean the stringers and any exposed areas of the staircase to remove debris or old adhesive. Inspect the stringers for any signs of damage or rot. If any structural issues are found, address them before proceeding with the installation.
Measuring and Cutting
- Precise Measurements: Carefully measure the width and depth of each tread and the height of each riser. It’s crucial to maintain consistent measurements throughout the staircase for a uniform and safe result.
- Accurate Cutting: Use a saw appropriate for your chosen tread and riser material (e.g., circular saw or miter saw) to make precise cuts. Double-check your measurements before making any cuts to avoid costly mistakes.
Installation Process
- Install Risers:
- Starting Point: Begin at the bottom of the staircase and work your way up.
- Secure Attachment: Apply construction adhesive to the back of each riser and place it against the stringer, ensuring it’s plumb (vertically straight) and level. Fasten the riser to the stringer using nails or screws, predrilling pilot holes if necessary to prevent splitting.
- Install Treads:
- Adhesive and Placement: Apply construction adhesive to the top of the riser and the stringer where the tread will rest. Carefully position the tread on top of the riser, ensuring it’s level and has a slight overhang (nosing) of about 1 inch.
- Secure Fastening: Use nails or screws to further secure the tread to the riser and stringer. Countersink the fastener heads and fill the holes with wood putty for a smooth finish.
- Repeat: Continue installing risers and treads in an alternating fashion until you reach the top of the staircase.
Finishing Touches
- Stair Nosing: If your treads don’t have a built-in nosing, attach a separate stair nosing piece to the front edge of each tread using adhesive and fasteners. This provides a finished look and adds a non-slip surface for safety.
- Trim and Molding: Install any necessary trim or molding, such as shoe molding or baseboard trim, to create a clean and finished appearance and conceal any gaps between the treads, risers, and walls.
- Sanding and Finishing: If using unfinished wood, sand any rough edges or surfaces on the treads and risers. Then apply a protective finish like polyurethane or varnish to enhance their durability and beauty.
Building Codes & Trends
- Code Compliance: Ensure the new treads and risers adhere to local building codes, including requirements for tread depth, riser height, and handrail specifications.
- Open Risers: Open riser staircases are a popular trend, but they require careful consideration for safety, especially in homes with children or pets.
- Mixed Materials: Combining different materials for treads, risers, and railings adds visual interest and can complement various design styles.
Conclusion
Installing new stair treads and risers can significantly enhance the look, feel, and safety of your staircase. Whether you’re replacing old, worn-out components or updating your staircase’s style, following the proper installation process and adhering to building codes is essential. With careful planning and execution, you can achieve a beautiful and functional staircase that will be enjoyed for years to come.
