Can a DIY Enthusiast Fit Composite Decking?

Home improvement projects are a favorite pastime for many DIY enthusiasts. Building a deck is often a rewarding endeavour, providing an inviting outdoor space for relaxation and entertainment. If you're considering composite decking, you might wonder if this is a project you can tackle as a DIY enthusiast. The answer is a resounding yes, but there are essential considerations to keep in mind.

Understanding Composite Decking

Before diving into the DIY aspect, let's briefly explore composite decking and why it's a popular choice:

What is Composite Decking?

Composite decking is a modern alternative to traditional wood decks. It's composed of a blend of recycled wood fibers and plastic materials, often enhanced with additives for strength and durability. The result is a deck material that's highly resistant to the elements, requires minimal maintenance, and offers a wide range of design options.

Why Choose Composite Decking?

  • Low Maintenance: Unlike wood, composite decking doesn't require regular staining, sealing, or constant upkeep. A simple periodic cleaning is usually enough to keep it looking great.

  • Durability: Composite decking can withstand harsh weather conditions, resist rot, mould, and insect damage, ensuring a long-lasting investment.

  • Aesthetics: It's available in various colours and textures, providing a wide array of design possibilities to match your style.

The DIY Approach

While DIY enthusiasts often relish the challenge of taking on home projects themselves, it's essential to understand what fitting composite decking entails and what it demands from you as a DIYer.

Planning and Design

Every successful DIY project starts with thorough planning and design:

  • Sketch Your Deck: Begin by sketching your deck design, considering the layout, size, shape, and features you want to incorporate.

  • Measure and Calculate: Take precise measurements of your outdoor space, ensuring your design fits comfortably within the available area. Calculate the number of composite boards, joists, beams, and hardware you'll need.

  • Check Local Codes: Research local building codes and regulations. Ensure your project complies with any necessary permits and requirements.

Tools and Materials

To fit composite decking properly, you'll need the right tools and materials:

  • Tools: Gather the necessary tools, including measuring tape, circular saw, cordless drill/driver, safety gear, level, and more, to ensure a smooth installation process.

  • Materials: Obtain the composite decking boards, framing materials, and hardware required for your project. Consider any additional features like railings, fascia boards, or accessories.

Site Preparation

Before you start installing your composite decking, ensure that your site is ready:

  • Clear the Area: Remove any vegetation, debris, or obstructions from the installation area.

  • Level the Ground: Ensure that the ground is level and well-drained to provide a stable foundation for your deck.

  • Inspect Existing Structures: If you're using an existing deck frame, carefully inspect it for structural integrity. Make any necessary repairs before proceeding.

Installation Process

The actual installation involves framing, decking, and finishing touches:

  • Frame Installation: Secure the frame to your house or support posts, ensuring it's level and securely anchored. Position and secure the joists for structural support.

  • Decking Installation: Start laying your composite boards from one end of the deck and work your way across. Use hidden fasteners for a clean, screw-free finish. Maintain proper spacing between boards and check for level and alignment.

  • Finishing Touches: Complete your deck with fascia boards or trim, install railings and any desired accessories, and conduct a final cleaning.

DIY Challenges and Considerations

Fitting composite decking as a DIY enthusiast is entirely achievable, but there are some challenges and considerations to keep in mind:

  • Experience Matters: While the installation process is straightforward, having some DIY experience, especially with woodworking, will be beneficial.

  • Safety is Paramount: Prioritise safety throughout the project. Invest in proper safety gear and follow all manufacturer recommendations and safety guidelines.

  • Time and Patience: Composite decking installation takes time and attention to detail. Be prepared for a potentially time-consuming project, especially if it's your first time working with composite materials.

  • Follow Manufacturer's Instructions: Every composite decking brand may have specific installation guidelines. Ensure that you carefully follow the manufacturer's instructions for your chosen product.

  • Permits and Codes: Check local building codes and obtain any necessary permits to ensure your project is compliant with regulations.


As a DIY enthusiast, fitting composite decking can be an enjoyable and rewarding project. With proper planning, the right tools, and attention to detail, you can create a beautiful and long-lasting outdoor space. While it may require some time and effort, the sense of accomplishment when you step back and admire your completed deck is well worth it. So go ahead, channel your inner DIY spirit, and transform your outdoor oasis with the beauty and durability of composite decking.
