Timber or Composite Decking – Which Is Best for Your Garden?

30th May 2025

Timber and composite decking each bring their own advantages, depending on your priorities—whether it’s upfront cost, durability, or aesthetics. Timber is a natural, affordable option loved for its warmth and flexibility, while composite decking is a long-lasting, low-maintenance solution designed for modern outdoor living.

Is Timber Decking Cheaper Than Composite?

Yes—timber decking is significantly cheaper upfront. In fact, timber boards are typically around a third of the cost of composite alternatives, making them ideal for homeowners on a budget or looking for a quick garden upgrade.

However, composite decking may be more cost-effective in the long run, thanks to its longer lifespan and minimal maintenance needs. If you plan to stay in your home for many years, it could be the better investment.

What Are the Pros and Cons of Timber Decking?

Pros:

• Lower initial cost
• Can be painted or stained in any colour
• Natural look and feel
• Easy to customise and repair

Cons:

• Requires regular maintenance (oiling/staining)
• Susceptible to rot, mould, and insect damage
• Can become slippery if not treated

Timber decking offers a classic garden aesthetic, especially popular in traditional or rural settings. It’s ideal for those who enjoy DIY projects and want to update their deck’s appearance over time.

What Are the Advantages of Composite Decking?

Composite decking is highly durable and built to last. Made from a mix of wood fibres and recycled plastic, it resists warping, splintering, and rotting—perfect for wet or shaded areas.

Key benefits include:

• Very low maintenance (no staining or sealing)
• Resistant to rot, insects, and UV fading
• Long lifespan—often 25+ years
• Consistent colour and finish

While you can’t paint composite boards, they’re available in a wide range of modern and natural colours that stay looking great with minimal effort.

Here you can see the composite decking returned to its original colour by pressure washing off the grime and dirt - evidence of composite decking maintaining its colouring over time.

Which Decking Material Lasts Longer?

Composite decking generally lasts much longer than timber.

• Timber decking lasts 10–15 years with proper care.
• Composite decking can last 25–30 years or more, especially when installed with a composite joists / subframe.

If longevity and low upkeep are your top priorities, composite is the clear winner.

Can You Repaint or Restain Composite Decking?

No—composite decking cannot be repainted or stained, which is one of its key differences from timber. The colour you choose at the start is the colour you’ll keep throughout its lifespan.

In contrast, timber decking can be stained, oiled, or painted multiple times, allowing you to refresh its appearance or completely change its look as your tastes evolve.

Which Decking Option Is Right for You?

Ask yourself:

• Do you want a quick, cost-effective garden feature and don’t mind a bit of upkeep? → Choose timber decking.
• Do you prefer a long-term, low-maintenance solution with a clean, modern finish? → Composite is your best bet.

Your decision may also come down to how long you plan to stay in your home, your budget, and how much time you’re willing to spend maintaining your outdoor space.
