Are you tired of your old carpeted stairs and want to upgrade to hardwood? Installing hardwood stairs is a great way to add value and style to your home.

How to install hardwood stairs can transform the aesthetic and functionality of your home, adding both elegance and value. This process involves careful planning, precise measurement, and a bit of craftsmanship to ensure a smooth installation that stands the test of time. Whether you’re renovating an existing staircase or building a new one, understanding the steps involved—from choosing the suitable materials and tools to finishing touches—will help you achieve a professional outcome.
This guide will walk you through each stage of installing hardwood stairs, providing tips and insights to make the project efficient and rewarding.
What Will You Need?
Before getting started, gathering the necessary tools and materials for installing hardwood stairs is essential. These include:
- Hardwood Stair Treads
- Hardwood Risers
- Nails or Screws
- Adhesive (if not using nails/screws)
- Measuring Tape
- Level
- Hammer
- Nail Punch/Counter sink bit (if using nails)
- Drill (if using screws)
- Saw (to cut treads and risers to size)
It’s also a good idea to wear proper safety gear, such as gloves and eye protection, during the installation process.
10 Easy Steps on How to Install Hardwood Stairs
Step 1: Measure and Plan
The first step in installing hardwood stairs is to measure and plan your project accurately. Begin by measuring the width and height of each stair. The width will determine how wide your stair treads and risers need to be, while the height will help you figure out how many steps you need and their rise. It’s crucial to maintain consistent measurements for each step to ensure a level and safe staircase.

Additionally, consider the type of hardwood you will use, taking into account the durability, color, and grain pattern that best suits your home. Once you have your measurements and material preferences, sketch a layout of your staircase and plan your installation process, determining which tools and materials will be necessary for each stage.
Step 2: Prepare the Existing Staircase
Before installing the new hardwood, it’s crucial to prepare the existing staircase. Start by removing any old flooring materials such as carpet, tiles, or previous wood treads. Use a pry bar to lift these materials, careful not to damage the underlying structure. Once all old materials are removed, inspect the condition of the stairs. Check for any loose or squeaky steps, and use screws to secure these firmly to prevent future noise or instability.
Sand down any rough areas to create a smooth, clean surface for the new hardwood treads and risers. Taking the time to prepare the existing structure will ensure a solid foundation for your new hardwood stairs.
Step 3: Cut the Treads and Risers to Size
With your measurements, it’s time to cut the hardwood treads and risers to fit your staircase. Use a saw to trim each piece according to your previously recorded dimensions. For precision, double-check each measurement before cutting, ensuring each tread and riser fits perfectly with no gaps or overhang. If your staircase is not a standard shape, you should make template adjustments to account for any irregularities.
Once all pieces are cut to size, perform a dry fit by temporarily placing them on the stairs to confirm accuracy before proceeding to the installation stage.
Step 4: Attach the Risers
Begin the installation by attaching the risers to the prepared staircase. If using adhesive, apply a generous amount to the back of each riser and press it firmly against the vertical face of the step. Ensure it is level and positioned securely before moving on to the next riser. For those using nails or screws, pre-drill holes to prevent the wood from splitting, and then fasten the risers with nails or screws, countersinking them slightly below the surface.
By securely attaching each riser, you establish a stable base for the subsequent installation of the treads, thereby enhancing the overall integrity of your new hardwood staircase.
Step 5: Install the Treads
Once the risers are in place, installing the hardwood treads is time. Apply adhesive to the top of each step, ensuring an even coverage that will provide a strong bond. Carefully position the tread on the step, pressing it firmly into place. If you’re using nails or screws, pre-drill holes through the tread to avoid splitting the wood, then secure it by nailing or screwing it into the underlying stair structure.

Make sure each tread is level and aligns perfectly with the risers below. The seamless installation of the treads will ensure the staircase looks aesthetically pleasing and is safe and comfortable to use.
Step 6: Secure the Treads
After installing all the treads, it’s vital to ensure they are securely fastened to provide a stable walking surface. Inspect each tread and use additional screws or nails if necessary to eliminate any movement or creaking sounds. Countersink any screws or nails and fill the holes with wood filler that matches your tread color for a seamless finish. This extra step ensures your treads are not only securely affixed but also maintain a sleek and polished appearance, enhancing the safety and aesthetic appeal of your new hardwood stairs.
Step 7: Add the Nosings
Once the treads and risers are securely attached, it’s time to install the nosings. The nosing is the slightly protruding part of the tread that extends beyond the riser. This component not only adds a finished look to your staircase but also provides added safety by increasing the surface area of each step. To install the nosings, apply adhesive to the underside and position it over the edge of each tread.
If fastening with nails or screws, use a pre-drilled hole to avoid splitting and ensure a snug fit. Countersink any nails or screws and fill them with wood filler for a polished look. Proper installation of the nosings will give your hardwood stairs a refined edge while enhancing safety and durability.
Step 8: Finish the Surface
With the installation of the treads, risers, and nosings complete, the next step is to finish the surface of your hardwood stairs. Start by sanding down uneven areas, ensuring a smooth and consistent surface. After sanding, thoroughly clean the stairs to remove any dust or debris that may interfere with the finish. Select a finish that suits your style and the type of hardwood you’ve used, whether it be varnish, polyurethane, or an oil-based finish.

Apply the finish evenly with a brush or cloth, following the manufacturer’s instructions for the best results. Allow ample drying time between coats if multiple applications are necessary. Finishing the surface enhances the visual appeal of your staircase and provides a protective layer, increasing its longevity and resilience against wear and tear.
Step 9: Install Railing and Balusters
The final step in completing your hardwood staircase installation is to install the railing and balusters, which provide both safety and an elegant finishing touch. Start by determining the correct placement for your balusters along each tread or the side of the staircase. Pre-drill small holes for each baluster to prevent the wood from splitting, and secure them using screws or specialized baluster fasteners.
Once the balusters are in place, attach the handrail, ensuring it is level and secure. Use brackets or screws to fasten the handrail to the wall and balusters, providing stability and support. Ensure all components are aligned and tight, as a sturdy railing system is crucial for safe stair usage. By installing the railing and balusters with precision, your hardwood staircase will be both beautiful and functional, enhancing your home’s overall safety and aesthetic appeal.
Step 10: Clean Up and Final Inspection
After installing your hardwood staircase, conducting a thorough clean-up and final inspection is essential. Begin by removing tools, materials, and debris from the work area. Use a damp cloth or vacuum to clean the stairs, removing any dust or sawdust that may have accumulated during installation. Once cleaned, examine each component of the staircase—treads, risers, nosings, and railings—to ensure everything is securely fastened and correctly aligned.
Check for any imperfections in the finish, such as drips, inconsistencies, or areas needing touch-ups, and address them as needed. This final inspection ensures that your new hardwood stairs are safe, flawless, and ready for use, providing a beautiful and functional addition to your home.
By following these steps and paying close attention to detail, you can successfully install a high-quality hardwood staircase that will enhance your home’s aesthetics, functionality, and value for years.
