When choosing materials for your outdoor space, one of the most significant decisions is whether to opt for timber or composite decking. Both materials have unique benefits, but how do they compare regarding durability, appearance, maintenance, and cost?

In this article, we’ll explore the differences between composite decking and timber decking to help you decide on your next decking project.
Check out the review here to help you make the right choice.
What Is Timber Decking?
Timber decking refers to the use of wood in building decks, often treated for outdoor use. Timber decking is known for its natural appearance, strength, and classic charm.
Types Of Timber Used For Decking
- Hardwood: Examples include species like Merbau, Spotted Gum, and Jarrah. Hardwood is dense, durable, and resistant to wear and tear, making it a top choice for decking.
- Softwood: Pine and Cedar are examples of softwood timber used for decking. They are more affordable but require more maintenance.
What Is Composite Decking?
Composite decking is a man-made material usually made from a combination of wood fibres and plastic. It is designed to mimic the look of timber but with added durability and minimal maintenance requirements.
Types Of Composite Decking
- Solid composite: Made from wood fibres and plastic, this decking offers a durable surface.
- Capped composite: A layer of protective plastic coating is applied to the composite material to enhance its durability.
How Does Composite Decking Compare To Timber In Terms Of Durability?
Durability is a key factor when choosing decking materials. Both timber and composite decking have different strengths in this area.
Timber Decking Durability
- Timber decking, especially hardwood, can be very durable if properly maintained.
- Timber can last 20-30 years, depending on the wood species and how well it is cared for.
- However, due to exposure to weather elements, timber is prone to warping, cracking, and splitting.
Composite Decking Durability
- Composite decking is designed to be highly durable and resistant to the elements.
- It won’t warp, crack, or splinter, and it’s more resistant to moisture and insects than timber decking.
- Composite decking can last up to 25-30 years with minimal maintenance.
How Does Composite Decking Compare To Timber In Terms Of Maintenance?
Regarding maintenance, composite decking offers a clear advantage over timber decking.
Timber Decking Maintenance
- Timber decking requires regular cleaning, sanding, and resealing to maintain its appearance and performance.
- It is also susceptible to stains, which may need special treatment.
- Timber decks need to be re-oiled or re-stained every couple of years, depending on exposure to the elements.
Composite Decking Maintenance
- Composite decking requires very little maintenance. You only need to clean it periodically with soap and water.
- Unlike timber, composite decking must not be stained, sealed, or painted.
- It is resistant to fading, mould, and mildew, which helps maintain its appearance over time.
How Does Composite Decking Compare To Timber In Terms Of Cost?
The initial cost of decking materials is an important consideration. Let’s compare the costs of timber and composite decking.
Timber Decking Cost
- Timber decking is generally more affordable upfront compared to composite decking.
- The cost varies depending on the type of timber, with hardwood options being more expensive than softwood options.
- However, the long-term cost of timber decking can be higher due to ongoing maintenance requirements.
Composite Decking Cost
- Composite decking typically has a higher upfront cost than timber decking.
- While it may be more expensive initially, it can save money in the long run due to its low maintenance and long lifespan.
- The total cost of composite decking will depend on the brand, style, and installation method.
Environmental Impact: Timber Vs Composite Decking
Choosing eco-friendly materials is becoming increasingly important for homeowners. Both timber and composite decking have environmental considerations.
Timber Decking Environmental Impact
- Timber is a renewable resource, making it a sustainable choice when sourced responsibly.
- The environmental impact of timber depends on where it is sourced. Look for timber certified by the Forest Stewardship Council (FSC).
- Some timber options, such as treated pine, may involve harmful chemicals that can affect the environment.
Composite Decking Environmental Impact
- Composite decking is made from wood fibres and plastic, making it less sustainable than timber.
- However, many composite decking brands use recycled materials, such as plastic bottles or reclaimed wood fibres, which reduces waste.
- The production process of composite decking has a larger carbon footprint than timber.
Aesthetic Appeal: Timber Vs Composite Decking
The aesthetic qualities of decking materials are a key consideration for many homeowners.
Timber Decking Aesthetic Appeal
- Timber decking offers a natural, warm, and classic look that many people prefer for outdoor spaces.
- The wood’s grain patterns, colour, and texture can be customised with stains and finishes.
- Timber can develop a unique patina as it ages, adding to its charm.
Composite Decking Aesthetic Appeal
- Composite decking is designed to mimic the look of timber, offering a similar appearance without the upkeep.
- While composite decking has improved over the years, some people feel it lacks the authentic feel of real wood.
- Composite decking comes in various colours and finishes, so it’s easy to find one that suits your style.
Which One Should You Choose: Timber Or Composite Decking?
Choosing between timber and composite decking depends on your priorities.
- If you want a natural, traditional look and are willing to invest time and money in maintenance, timber decking may be the right choice.
- Composite decking might be a better option if you prefer a low-maintenance option that lasts longer and requires minimal upkeep.
Conclusion
In conclusion, timber and composite decking offer distinct advantages, and the right choice depends on your specific needs and preferences. Before making your final decision, consider the durability, maintenance requirements, cost, environmental impact, and aesthetic appeal of each material.
Whatever you choose, ensure that your deck enhances the beauty and functionality of your outdoor space for years to come.
Frequently Asked Questions
What Is The Main Difference Between Composite Decking And Timber Decking?
The primary difference lies in the material composition. Timber decking is made from natural wood, providing a classic, traditional look, but requires regular maintenance. Composite decking, on the other hand, is made from a mix of wood fibres and plastic, offering a low-maintenance solution that mimics the appearance of wood without the need for staining or sealing.
How Long Does Composite Decking Last Compared To Timber?
Composite decking typically lasts 25-30 years with minimal maintenance, thanks to its durability and resistance to elements like moisture and pests. Timber decking, if well-maintained, can last for 20-30 years but is more susceptible to issues like warping, cracking, and fading, which can shorten its lifespan.
Is Composite Decking More Expensive Than Timber Decking?
Yes, composite decking generally has a higher upfront cost than timber decking. However, it requires significantly less maintenance, which can make it more cost-effective in the long term. While initially cheaper, timber decking incurs higher long-term costs due to its need for regular maintenance such as sealing, staining, and re-oiling.
