How to Install Square Balusters Without Shoes: A Comprehensive Guide

Are you looking to add a touch of elegance to your staircase? Installing square balusters is a great way to achieve a modern and sophisticated look. And the best part? You can do it without the need for shoes! In this comprehensive guide, we will walk you through the step-by-step process of installing square balusters without shoes, ensuring a seamless and sturdy installation.

Before we dive into the installation process, let’s first understand what square balusters are. Square balusters, also known as spindles or pickets, are vertical posts that provide support and safety to your staircase. Unlike traditional rounded balusters, square balusters offer a sleek and contemporary appearance, making them a popular choice among homeowners.

Preparing for the Installation

Gathering the Essential Tools and Materials

Before you begin the installation process, it’s important to gather all the necessary tools and materials. Some of the essential items you will need include a tape measure, a pencil, a drill with a drill bit, a jigsaw, a level, screws, adhesive, a rubber mallet, a chisel, sandpaper, and a paintbrush. Additionally, you will need square balusters, which you can purchase at your local home improvement store.

Measuring and Determining the Quantity of Balusters

Accurate measurements are crucial when installing square balusters without shoes. Start by measuring the distance between each newel post or handrail. This will help you determine the number of balusters needed for your staircase. As a general rule, the spacing between balusters should not exceed 4 inches. Measure the length of each baluster and calculate the required quantity based on the measured spacing.

Preparing the Staircase

Before you can install the square balusters, you need to prepare the staircase. Start by removing any existing balusters. Use a screwdriver or a pry bar to carefully remove the screws or nails securing the balusters in place. Be cautious not to damage the surrounding wood or the newel posts. Once the old balusters are removed, clean the surface of the staircase to ensure a smooth installation.

Marking and Drilling Holes

Marking the Baluster Positions

Accurate marking is essential to ensure that the balusters are evenly spaced and aligned. Start by marking the centerline of the bottom tread and the top landing. Measure the desired spacing between the balusters and mark the positions accordingly. Use a straight edge or a level to connect the marks vertically, creating reference lines for drilling the holes.

Drilling the Holes

Once the positions are marked, it’s time to drill the holes for the balusters. Use a drill with a drill bit that matches the diameter of your balusters. Start by drilling a pilot hole at each marked position. Then, enlarge the holes using a larger drill bit or a jigsaw. Make sure to drill deep enough to accommodate the length of the balusters.

Installing the Balusters

Applying Adhesive

To secure the balusters in place, apply a small amount of adhesive to the bottom of each baluster. The adhesive will help create a strong bond between the baluster and the drilled hole. Be careful not to use too much adhesive, as it can ooze out and create a messy appearance.

Inserting the Balusters

Once the adhesive is applied, gently insert the balusters into the drilled holes. Use a rubber mallet to tap them into place, ensuring a snug fit. Make sure the balusters are aligned vertically and are level with the reference lines you created earlier. Continue this process for all the balusters along the staircase, maintaining consistent spacing.

Securing the Balusters

To ensure the balusters are securely fastened, you have several options. One method is to use screws to secure the balusters from the underside of the handrail or the bottom tread. This method provides additional stability and prevents the balusters from shifting over time. Alternatively, you can use dowels to secure the balusters by inserting them into pre-drilled holes in both the balusters and the staircase. Choose the method that best suits your preference and the design of your staircase.

Filling and Sanding

Filling Gaps and Holes

After installing the balusters, you may notice small gaps or holes between the balusters and the staircase. To achieve a seamless look, fill these gaps and holes with wood filler. Use a putty knife to apply the filler, ensuring it is level with the surrounding surface. Allow the filler to dry according to the manufacturer’s instructions before proceeding to the next step.

Sanding the Surfaces

Once the filler is dry, sand the surfaces of the balusters and the staircase. Start with a rough-grit sandpaper to remove any excess filler and smooth out uneven surfaces. Gradually switch to finer-grit sandpaper to achieve a polished finish. Sand in the direction of the wood grain to avoid causing scratches or damage. After sanding, wipe away any dust with a clean cloth.

Priming and Painting

Choosing the Right Paint

Before you can paint the balusters, it’s important to choose the right type of paint. Consider the material of your balusters and the desired finish. If your balusters are made of wood, opt for a high-quality interior paint that offers durability and a smooth finish. If you prefer a natural wood look, you can skip the paint and apply a clear protective finish instead.

Preparing the Surfaces

Prior to painting, prepare the surfaces by cleaning them thoroughly. Remove any dust or debris using a damp cloth. If necessary, lightly sand the surfaces to create a smooth texture for better paint adhesion. Use painter’s tape to mask off any areas you don’t want to be painted, such as the handrail or the staircase treads.

Applying the Paint

Once the surfaces are prepared, it’s time to apply the paint. Start by applying a coat of primer to ensure better paint adhesion and coverage. Allow the primer to dry completely before proceeding with the paint. Apply the paint in thin, even coats, using a brush or a roller. Allow each coat to dry before applying additional coats. Once the final coat is dry, remove the painter’s tape and admire your freshly painted square balusters.

Adding Finishing Touches

Decorative Caps

To enhance the visual appeal of your square balusters, consider adding decorative caps. Decorative caps come in various designs and materials, such as metal or wood. They can be easily installed by attaching them to the top of each baluster. Decorative caps not only add a touch of elegance but also provide additional protection to the baluster ends.

Ornamental Designs

If you want to take your square baluster installation to the next level, consider incorporating ornamental designs. These designs can be added to the balusters themselves or to the handrail. Ornamental designs can range from simple carved patterns to intricate scrollwork, allowing you to customize your staircase to match your personal style and preferences.

Maintenance and Care


To maintain the beauty of your square balusters, regular cleaning is essential. Use a soft cloth or a feather duster to remove dust and debris from the surfaces. Avoid using harsh chemicals or abrasive cleaners, as they can damage the finish. Instead, opt for a mild detergent mixed with water for gentle cleaning.

Inspecting for Damage

Regularly inspect your square balusters for any signs of damage or wear. Check for loose screws, cracks, or splinters. If you notice any issues, address them promptly to prevent further damage and ensure the safety of your staircase. Tighten any loose screws, repair cracks with wood filler, or consider replacing damaged balusters if necessary.


Over time, the finish on your square balusters may wear off or become dull. If you wish to restore the original beauty, you can refinish the balusters. Start by sanding the surfaces to remove the old finish. Apply a new coat of paint or clear protective finish, following the same steps outlined in the “Priming and Painting” section. Refinishing your balusters will give them a fresh look and extend their lifespan.
