Preparation
Proper preparation is key for a successful and long-lasting hardwood stair installation. Here's what you need to do:
Remove Old Flooring
- Carpet: If your stairs are carpeted, start by removing the carpet, padding, and tack strips. Use a pry bar to carefully lift the carpet and padding, and pliers to remove staples or tacks.
- Other Flooring: If you have existing tile, linoleum, or hardwood, you'll need to remove it to expose the subfloor. Check online resources for specific removal instructions for your flooring type.

Inspect the Subfloor
- Squeaks: As you work, walk up and down the stairs, listening for squeaks. Mark these areas. Secure loose stair components with screws to eliminate squeaking.
- Levelness: Place a level on each tread and riser. Look for significant gaps indicating unevenness. You may need to sand down high spots or fill low spots with a leveling compound for the hardwood to lay smoothly.
- Cleanliness: Thoroughly vacuum and sweep the subfloor to ensure it's free of debris that could hinder adhesion.
Acclimate Flooring to Prevent Warping
Engineered hardwood is more stable than solid wood, but acclimation is still important. Leave the unopened flooring boxes in the room where they will be installed for at least 72 hours. This allows the wood to adjust to the humidity levels of your home, minimizing expansion or contraction after installation.

Installation
Now, it's time for the exciting part – installing your beautiful new engineered hardwood floors!
Start with the Risers
- Measure and Cut: Measure each riser's height and width. Transfer your measurements to the engineered hardwood boards and cut them to size using a circular saw or miter saw.
- Apply Adhesive: Apply a bead of construction adhesive to the back of the riser board.
- Position and Secure: Place the riser in position, ensuring it's level and flush against the back of the tread above. Secure the riser with finishing nails along the top and bottom edges.
Installing the Treads
- Measure and Cut: Measure the depth of the tread (front to back) and the overall width, including the nosing overhang. Cut your engineered hardwood flooring planks accordingly.
- Dry Fit: Place the tread on the step, making sure it fits correctly and aligns with the riser behind it.
- Apply Adhesive: Apply construction adhesive to the subfloor, following the manufacturer's recommended pattern.
- Position and Secure: Carefully install the tread, ensuring it's snug against the riser. Use finishing nails to secure the tread to the subfloor.
Special Considerations
- Landings: Measure and cut the flooring as you would for regular treads, making any adjustments if they are not square.
- Angled Stairs: For angled stair sections, you may need to make angled cuts on your treads and risers. Use a protractor or an angle measuring tool to determine the correct angles.
Tips
- Work your way from the bottom of the staircase to the top.
- Use a damp cloth to wipe away any excess adhesive immediately.
- If you encounter gaps, a small amount of color-matched wood filler during the finishing stages can help disguise them.

Finishing Touches
With the main installation complete, a few finishing touches will give your stairs a polished and professional look.
Filling Nail Holes
- Choose the Right Filler: Look for a wood filler that closely matches the color of your hardwood flooring.
- Application: Use a putty knife to apply a small amount of filler to each nail hole, slightly overfilling the hole.
- Smoothing and Removal: Let the filler dry per the manufacturer's instructions. Then, use fine-grit sandpaper to gently sand the filler flush with the wood surface.
Caulking and Sealing
- Caulking: Use a paintable caulk to fill any gaps where your new stairs meet the walls or trim. This will give a seamless appearance.
- Sealing (Optional): While engineered hardwood often comes pre-finished, an additional coat of sealant can provide extra protection and shine. Choose a sealant compatible with your flooring's finish.
Stair Nosing
- Installation: Follow the manufacturer's instructions for your specific stair nosing product. Typically, stair nosing is attached using both adhesive and finishing nails.
- Aesthetics: Ensure your stair nosing blends seamlessly with the hardwood flooring for a cohesive look.
Always refer to the manufacturer's instructions for your specific flooring and stair nosing products, as application steps may vary slightly.

Tips and Troubleshooting
Common Mistakes
- Not Acclimating Flooring: Skipping the acclimation step can lead to gaps or warping as the wood adjusts to your home's humidity.
- Improper Nailing: Nailing too close to the edges of boards can cause splitting. Follow the manufacturer's recommended spacing for nailing.
- Ignoring Expansion Gaps: Always leave small expansion gaps around the perimeter of your flooring where it meets walls or baseboards. This allows natural expansion and contraction.
Dealing with Squeaky Stairs
If squeaks develop after installation, locate the noisy spot. Apply a bit of wood glue to the joint between the tread and riser and clamp overnight. If the squeak persists, you may need to drill from below and countersink screws through the subfloor to secure the tread and riser more tightly.

Addressing Expansion Gaps
Small expansion gaps can usually be concealed with caulk or carefully placed quarter-round molding.
Additional Tips
- Work with a helper: Having an extra set of hands for measuring, cutting, and holding pieces can make the process smoother.
- Take your time: Patience is key, especially if this is your first stair installation project.
- Enjoy the process: Focus on the transformation you're creating and the satisfaction of a successful DIY job.
