8 Easy Steps on How to Build Stairs in Garage

Step 1: Plan and Measure 

Start by planning the staircase layout and measuring the height from the garage floor to the landing or upper level. Divide this total height by the desired riser height (usually 7 to 7.5 inches) to determine the number of steps needed.

Once you calculate the number of steps, decide on the tread depth (10 to 12 inches is standard). Use a measuring tape and level to ensure accurate measurements. Accurate planning is crucial for building safe and functional stairs.

Step 2: Cut the Stringers 

Using the measurements from Step 1, mark the outline of the stringers on sturdy lumber, such as 2×12 boards. The stringers are the framework that supports the steps, so precision is key. Use a carpenter’s square to mark the rise and tread dimensions on the wood, ensuring consistency throughout.

Once marked, carefully cut along the lines using a circular saw for the straight edges and a jigsaw to finish the corners. Double-check your cuts for accuracy, as uneven stringers can compromise the stability of the stairs.

Step 3: Attach the Stringers 

After cutting the stringers, position them against the structure where the stairs will be installed. Secure the top of each stringer to the upper landing using metal hangers or brackets designed for staircase construction. Ensure the stringers are level and evenly spaced apart, typically 16 inches on the center for residential stairs.

Anchor the bottom of the stringers to the ground or a concrete pad to provide stable footing. Double-check all connections to guarantee a secure and durable staircase framework.

Step 4: Install the Treads and Risers 

With the stringers securely in place, it’s time to attach the treads and risers. Start by measuring and cutting the treads to fit the width of the stringers. If risers are included in the design, cut them to size. Begin at the bottom of the staircase and work your way upward, attaching each riser first (if applicable) before securing the tread above it.

Use construction adhesive and screws to fasten the pieces securely, ensuring they are flush and level. Check for consistent overhangs on the treads to maintain a uniform appearance.

Step 5: Sand and Finish the Stairs 

Once the treads and risers are installed, sand the entire staircase to eliminate any rough edges or splinters. Focus on smoothing the surfaces of the treads and the sides of the stringers to create a polished finish. After sanding, apply a protective finish such as paint, stain, or a waterproof sealant, depending on the intended look and use of the stairs.

This step enhances durability and aesthetics, ensuring the staircase is both functional and visually appealing. Allow the finish to dry completely before proceeding to the next step or using the stairs.

Step 6: Inspect and Test the Stairs 

After the finish has dried completely, thoroughly inspect the staircase to ensure all components are secure and properly aligned. Check that the treads and risers are firmly attached, and confirm there are no loose screws or uneven surfaces that could pose a safety risk.

Once satisfied with the inspection, carefully test the stairs by walking up and down them, paying attention to stability and comfort. Address any issues immediately before finalizing the project to ensure the staircase is safe and ready.

Step 7: Clean and Maintain the Stairs 

Once the staircase is finished and safely installed, take the time to clean off any dust, debris, or residue from construction. Use a damp cloth or appropriate cleaning solution based on the finish applied.

Regular maintenance is essential to prolong the stairs’ life—this includes routinely inspecting for wear and tear, tightening any loose components, and cleaning to prevent grime build-up. Proper care ensures your staircase remains safe, functional, and visually appealing for years.

Step 8: Add Finishing Touches 

To complete your staircase project, consider adding finishing touches that enhance both its functionality and aesthetic appeal. Install handrails or balusters if they are part of the design, ensuring they are securely fastened and meet safety regulations.

Consider adding non-slip treads or strips for safety, especially in high-traffic or wet areas. Finally, consider decorative elements, like molding or paint, that complement the surrounding decor and give the staircase a polished, professional look. These final additions can elevate the overall appearance and ensure the staircase fits seamlessly into your space.

By following these easy steps, you can successfully build stairs in your garage that are both functional and visually appealing. Remember to prioritize safety during every step of the process, from planning and measuring to adding finishing touches.
