Will composite decking last longer than wood?  Every homeowner will love to install a decking material that will last longer. A long-lasting decking will help you save money on maintenance and part replacement. But, with the various decking materials in the market, knowing the one that will last longer might not be easy, especially if you are new to decking. Ultradecking composite decking has been advertised as a long-lasting decking compared to wood. In this article, we will compare composite decking and wood to help us know which will last longer.

Wood Decking

Wood or timber decking is a natural decking material you can use in your home or garden. It is also the oldest decking material before the advent of composite decking.


There are different types of wood decking you can purchase in the market. They are the pressure-treated woods, untreated wood, hardwoods and deckings made from redwood and cedar. Of all these types of wood decking, hardwood decking tends to last longer. 

Untreated wood deckings are the most susceptible to damage. They are easily targeted by wood-eating insects and can easily rot and decay. These types of wood decking can only last for a short period.

Pressure-treated wood deckings are deckings that have been treated with chemicals. The chemicals in the wood prevent insects from damaging the wood. It also keeps the wood from rotting. Deckings made from hardwoods are the most durable type of wood decking. They are naturally resistant to wood-eating insects and will not decay.


Timber decking is beautiful and can easily blend with the surroundings. Homeowners who love natural decking types do go for wood deckings. Wood is also an affordable decking material and is good for building decks on a budget.


The bad side of the wood is that it has many drawbacks. One of its drawbacks is that it does not last long like composite. The average lifespan of timber decking is 15 years. 

Timber decking is not durable; it is a natural decking material making it susceptible to damage. Wood also has less resistance to the weather elements. It is not water-resistant and will absorb moisture easily from the atmosphere. Wood can also break, warp and splinter.

Apart from that, wood is difficult to maintain. Maintaining wood can be stressful. Since the colour of wood fades, it will require repainting and staining to make it look attractive. Wood also needs sanding, sealing and there is the possibility of part replacement if its breaks.

Composite Decking

Composite decking, also known as wood-plastic decking, is made from wood fibres and plastic. It is not a natural decking type like wood since it contains recycled plastic material. 


There are different types of composite decking, the capped and uncapped decking. Capped decking is good for installing in both dry and moisture areas, while uncapped decking is good for installing in dry areas.

 Besides that, there is also the grooved and ungrooved decking. The grooved decking has hollows by its sides and is good for homeowners who prefer the hidden installation. In contrast, the ungrooved decking does not have hollows by its sides and is good for homeowners who prefer surface installation. Let us consider the advantages and drawbacks of composite to help us know whether composite decking lasts longer than wood.


Composite decking is more durable than wood. It can withstand heavier foot traffic than wood decking. Wood-plastic decking is unlikely to break or crack like timber.

Furthermore, composite is resistant to termites—no need to worry about termites damaging your decking, unlike wood.
