PVC Decking

When creating the perfect outdoor space, choosing decking material is crucial. Two popular options are composite and PVC decking, each offering unique benefits and challenges. This guide delves into these materials, helping you make an informed decision for your home. Don’t forget to check out the difference between composite vs PVC decking explained at Ovaeda.

What is Composite Decking?

Composite decking is made from a blend of wood fibres and plastic, offering a balance of aesthetic appeal and durability. Its low-maintenance appearance is a direct reflection of its realistic wood-like appearance.

Pros of Composite Decking

Durability: Composite decking is extremely durable and resistant to wear and weather. It doesn’t splinter, warp, or rot like traditional wood, making it a long-lasting option for your outdoor space.

Natural Appearance: Composite decking looks quite similar to genuine wood, one of its main advantages. It can be challenging to distinguish between composite and natural wood at first glance.

Variety of Colors: Composite decking has various colour options and can even mimic different wood species. This versatility allows homeowners to match their decks with their desired aesthetic.

Maintenance: While it’s significantly easier to maintain than wood, composite decking is only partially maintenance-free. Clean it periodically if you want to avoid dirt and grime accumulating.

Eco-Friendly: Composite decking materials often include recycled content, which may pique the interest of eco-conscious homeowners.

Cons of Composite Decking

However, there are some downsides to composite decking:

Cost: Composite decking is initially more costly than wood decking. However, it can save you money in the long run due to reduced maintenance and longer lifespan.

Maintenance: While it requires less maintenance than wood, composite decking may still need cleaning and occasional sealing to maintain its appearance.

Structure: Composite decking often requires a treated lumber frame for support to ensure the best performance.

Colour Fading: Some composite decking materials may experience slight colour changes over time due to exposure to sunlight and the elements.

What is PVC Decking?

PVC decking, constructed entirely from polyvinyl chloride, stands out for its all-plastic composition. It’s known for being highly durable and low maintenance, though with a more synthetic appearance.

Pros of PVC Decking

Low Maintenance: PVC decking is highly resistant to the elements and easy to clean. It won’t warp, rot, or splinter and doesn’t require sealing or staining.

Durability: PVC decking is scratch-resistant and has a longer lifespan than wood or composite materials.

Colour Options: Homeowners can choose the PVC decking that best meets their preferences from various shapes and colours, much like composite decking.

Lightweight: PVC decking is lighter than wood or composite materials, making it easier to handle and install.

Cons of PVC Decking

However, PVC decking has its drawbacks:

Cost: PVC decking tends to be more costly than wood and composite decking. The first investment may put off some homeowners.

Aesthetics: While it is available in various colours and styles, PVC decking often has a more synthetic appearance than wood or composite options.

Sun Exposure: PVC decking may be prone to fading and heat retention, particularly in areas with intense sunlight. This can affect its long-term appearance.

Repair: If damaged, PVC decking can be more challenging to repair than composite or wood, as it may require the replacement of entire boards.

How to Choose Between Composite and PVC Decking

Understanding Your Needs and Preferences

When it comes to decking, one size doesn’t fit all. The first step is to assess your personal needs. Ask yourself:

  • Durability and Maintenance: How much time and effort will you invest in upkeep?
  • Aesthetic Appeal: Do you prefer the natural look of wood or a more modern, synthetic appearance?
  • Usage: Will your deck face heavy foot traffic, or is it more for aesthetic appeal?
  • Climate: Consider the climate in your area. Some materials may fare better in certain weather conditions than others.

Evaluating Aesthetics and Style

Composite decking offers a more natural, wood-like appearance, while PVC decking has a distinct, sleek look. Consider the overall style of your home and garden. Do you want your deck to blend in with nature or stand out as a modern element?

Budget Considerations

It’s crucial to balance your dream deck with your budget. Generally, PVC decking tends to be more expensive than composite decking. However, consider long-term costs like maintenance and durability when making your decision.

How to Install Composite Decking


Gather all of your supplies and equipment before you begin. You’ll need composite decking boards, a saw, a drill, screws, and a tape measure, to name a few.

  1. Laying the Foundation: Start by building a strong, level foundation. If you’re replacing an old deck, ensure the substructure is sound.
  2. Spacing and Alignment: When installing composite boards, leave appropriate gaps for expansion and contraction. Use spacers for uniformity.
  3. Securing the Boards: Use hidden fasteners or composite deck screws for a neat finish. Ensure each board is securely fastened to the joists.

Finishing Touches:

Once all boards are in place, add the finishing touches, like trim boards and railings. Remember, composite materials can expand or contract, so keep an eye on spacing.

How to Install PVC Decking


As with composite decking, gather your tools and materials. PVC decking materials include the PVC boards, screws, a saw, and possibly a hidden fastening system.

  1. Creating a Solid Base: Ensure your deck frame is sturdy and level. PVC is lightweight, so a solid base is crucial for stability.
  2. Installing the Boards: Unlike composite, PVC doesn’t expand as much. However, spacing is still crucial for drainage and ventilation.
  3. Fixing the Boards: Use screws designed for PVC decking to avoid splitting. Some PVC decking systems come with a groove system for hidden fasteners.

Avoiding Common Pitfalls:

Be mindful of over-tightening screws, as PVC can crack. Also, ensure adequate ventilation to prevent heat buildup on your new PVC deck.

To Wrap Up

Choosing composite and PVC decking ultimately depends on your needs, preferences, and budget. Both options offer advantages and disadvantages, so take the time to evaluate what matters most to you and your outdoor space. Whether you prioritise the natural beauty of wood-like composite or the low-maintenance durability of PVC, there’s a perfect decking solution for you.
