You've decided to enhance your outdoor living space with a brand new deck, but now you're facing the age-old dilemma: Should you go for composite decking or traditional timber? As a DIYer or homeowner, this choice is massively important - your decision will determine the longevity, aesthetics, and maintenance requirements of your new outdoor haven. Fear not! We've compiled the ultimate guide, delving deep into the core differences between composite and timber decking to help you make an informed decision.

What are Composite Decking and Timber Decking?

Composite Decking

Composite decking is made up of a combination of wood fibres and synthetic materials, such as plastic. Leading brands carefully craft these components into durable, eco-friendly boards that closely resemble the natural beauty of wood without its drawbacks. Today's composite decking options are stain-resistant, low-maintenance, and built to withstand the test of time.

Timber Decking

Timber decking is made from natural wood, with options ranging from budget-friendly pressure-treated pine to high-end hardwoods like Ipe. Timber decking is beloved for its authentic look and feel, offering a classic choice for homeowners who prefer a more traditional aesthetic. However, timber requires consistent maintenance to preserve its beauty and prevent decay.

Comparing Composite Decking and Timber Decking

Durability and Longevity

When it comes to durability, composite decking takes the crown. Thanks to its unique blend of materials, composite decks resist damage from insects, moisture, and heat, making them perfect for withstanding various climates. On the other hand, timber decks are more susceptible to warping, rotting, and insect damage, shortening their lifespan.

Maintenance and Upkeep

Composite decking is low-maintenance, requiring just an occasional cleaning with soap and water to keep its pristine appearance. In contrast, timber decks require regular sealing, staining, or painting to protect against moisture and prevent deterioration. This additional maintenance can be time-consuming and expensive for homeowners.

Cost Comparison

While composite decking tends to have a higher initial cost than timber, its long-term value is undeniable. With minimal maintenance expenses and a longer lifespan, composite decking often proves more cost-effective in the long run. Timber decking may be cheaper upfront, but keep in mind that maintenance and replacement costs can add up over time.


Many composite decking options are made from recycled materials, making them an eco-friendly choice for homeowners. Timber decking's sustainability depends on the wood species and source, with some hardwoods contributing to deforestation. Look for suppliers that offer sustainably harvested or FSC-certified wood to limit your environmental impact.

Aesthetic Appeal

Both composite and timber decking have their unique charm. Composite decking comes in various colors and grains, mimicking the look of wood without the maintenance. Timber decking offers an authentic wood appearance that some homeowners find irreplaceable. Ultimately, the aesthetic appeal is subjective and should align with your personal tastes and style.


Composite decking and timber decking each have their pros and cons, catering to different preferences in terms of durability, maintenance, cost, sustainability, and aesthetics. As a DIYer or homeowner, your decision will depend on your priorities and desired outcome for your deck.
