There are various building materials you can use in making decks in your home. Builders use materials like wood decking and composite decking  from ultradecking in making decks. These building materials differ from each other in various ways. Here are seven differences between wood decking and composite decking.

Differences Between Wood and Composite Decking


One major difference between wood and composite decking is that compsite can not splinter like wood. Composite decking is a strong and durable building material and can not crack, unlike wood decking. It is resistant to the element and will not splinter due to prolonged use. But wooden decks can warp or splinter due to the elements when compared to wood-plastic decking.

Cost Price

When it comes to the cost price, wood decking is lower in price compared to composite decking. If you are on a low budget, wood decking is a great alternative to choose. Lumber decking is affordable to purchase, unlike composite decking that is quite pricey.

 Does Not Leach Chemicals

Additionally, pressure-treated wood decking contains chemicals that can leach into the soil. The chemicals get into the soil when the wood cracks, splits or warps. These chemicals are toxic and can make the soil unfit for planting. Unlike timber decking, composite decking does not leach chemicals into the ground.

You can use composite decking to build your garden bed without any doubt that chemicals will get into the soil. The wood-plastic decking is so strong that it can not crack or rot. Wood-plastic deck is the best garden bed material because it doesn’t leach chemicals like wood decking.


Composite deckings are resistant to moisture, unlike lumber decking. When in contact with water, composite decks can not absorb water. Composite decking makers fabricated the decking in such a way that it is well sealed. It is resistant to dampness and cannot swell when in contact with fluids.

Wood decking, on the other hand, can absorb water or moisture which makes them prone to damage. Composite decking can thrive in a damp environment compared to wood deckings. You can install composite decking in high moisture conditions without it decaying.


Furthermore, the cost to maintain the lumber deck is higher compared to wood-plastic composite. If you install composite decking, you don’t have to worry about replacing its parts over time. Unlike timber decking that requires parts replacement as times goes on. Also, lumber decking require painting or staining to make them look attractive since the colour fades over time.

Composite decking does not require staining, sealing or painting. It is very easy to maintain and will not cost you a huge sum of money. All you have to do to make your composite decking look good is to sweep it and clean it with soapy water.


Although, both wood-plastic decking and lumber decking are easy to work on. But composite decking can be curved easily to any desired shape or style than wood decking.  When it comes to durability, composite boards are no match to wood deckings. Composite deckings are strong and resistant to any weather conditions. They can not split, warp or crack. Wooden decking on the other hand, can warp or crack over time due to wear and tear.


Finally, when it comes to lifespan, composite decking is longer lasting. It can last for several decades without getting damaged. Wood-plastic decking can get damaged by wood-eating insects. Aside from that, composite is also resistant to rot and decay. It can thrive in a wet environment without getting damaged. Unlike composite decking, wood decking can not last long for several decades.

Timber decking is susceptible to insect damage when compared to composite decking. Wood-eating insects like termites can damage a wood decking. Unlike lumber decking, termites and other wood-destroying insects can not eat composite checking.

These insects can bore through a wood decking but can not penetrate a composite decking. Also, timber decking can get damaged due to wear and tear. Timber decking has a standard lifespan of 10 to 20 years, while Composite decking can last over 20 years with the proper care and maintenance.


The differences between wood and composite decking are easy to pinpoint. Their lifespan, maintenance cost, cost price, durability and ability to leach chemicals make them differ.
