Step-by-Step Guide to Installing Pergola Flooring like a Pro


Installing flooring for a pergola can enhance its functionality and aesthetics, creating a comfortable outdoor space.

Whether you’re building a new pergola or looking to upgrade the existing one, this step-by-step guide will help you install pergola flooring like a pro.

Materials and Tools You’ll Need:

Flooring Material:

Choose your preferred flooring material, such as wood, composite decking, stone, or concrete pavers.

Support Structure:

Ensure your pergola has a sturdy support structure in place, including posts, beams, and joists.

Measuring Tools:

Tape measure, level, and a framing square.

Safety Gear:

Safety glasses, gloves, and a dust mask (if necessary).


Appropriate screws, nails, or anchors for your chosen flooring material.

Power Tools:

Circular saw, drill, screwdriver, and a miter saw (if using wood).

screws and Nails:

Appropriate for outdoor use and compatible with your chosen flooring material.

Concrete Mix and Forms (if installing a concrete slab).

Plan and Prepare

Before you start installing the flooring, carefully plan your project and prepare the area:

Measure the pergola area to determine the amount of flooring material needed. Make sure to account for any overhang and the size of individual pieces.

Ensure your pergola’s support structure is in good condition. Replace or repair any damaged components.

If you’re working with an existing pergola, remove any old flooring material and clean the surface thoroughly.

If you’re building a new pergola, construct the support structure first, including posts, beams, and joists. Ensure they are level and securely anchored.

Choose the Flooring Material

Select a flooring material that suits your style, budget, and maintenance preferences. Popular options include:


Traditional and visually appealing, but it requires regular maintenance.

Composite Decking:

Low-maintenance, durable, and available in various colors and styles.


Elegant and natural, but it can be more labor-intensive to install.

Concrete Pavers:

Sturdy and versatile, offering a wide range of design options.

Prepare the Substrate

The substrate is the surface on which you’ll install the flooring material. Its preparation varies depending on your chosen material:


Ensure the joists are level and spaced appropriately for your wood planks. Use a framing square to check for squareness. Install a vapor barrier to protect against moisture.

Composite Decking: Follow the manufacturer’s guidelines for joist spacing and support requirements. Typically, they can be installed directly on the joists.

Stone: Excavate the ground and level it. Add a layer of sand for stability.

Concrete Pavers:

If using a concrete slab, pour the concrete into prepared forms, level it, and allow it to cure. Make sure the surface is smooth and even.

Lay the Flooring Material

Now it’s time to lay the chosen flooring material:

Wood: Start at one end of the pergola and place the first plank along the edge of the joist. Use screws to secure it in place.

Continue adding planks, ensuring they have even spacing between them.

Composite Decking:

Install the first board flush with the edge of the joist, using special composite decking screws. Continue adding boards, leaving a small gap between them to allow for expansion.


Lay the stones in your desired pattern, starting from one corner. Use a rubber mallet to tap them into place and ensure they’re level. Fill the gaps with sand or mortar.

Concrete Pavers:

Begin at one corner and place the pavers tightly together. Use a rubber mallet to ensure they are level and securely set in place.

Cut and Trim

Inevitably, you’ll need to cut flooring material to fit around corners or obstacles. Use a circular saw or miter saw for wood and a diamond-bladed wet saw for stone or concrete pavers.

Secure the Flooring

After you’ve laid all the flooring material, secure it to the joists or substrate. Use the appropriate fasteners for your chosen material, ensuring they are spaced according to the manufacturer’s guidelines.

Finishing Touches

Once the flooring is secure, there are some finishing touches to consider:


Apply a protective finish, such as sealant or stain, to protect it from the elements and enhance its appearance.

Composite Decking:

No staining or sealing is necessary, but you can clean it periodically to maintain its appearance.


Seal the stone to protect it and enhance its color. Use a stone sealer and follow the manufacturer’s instructions.

Concrete Pavers:

Consider applying a concrete sealer for added protection and to enhance their appearance.

Enjoy Your Pergola

With the flooring installed and all the finishing touches complete, your pergola is ready to be enjoyed.

Arrange your outdoor furniture, add some potted plants, and you’ll have a beautiful and functional outdoor space.

This includes cleaning, sealing (if necessary), and inspecting for any damage or loose fasteners.
