Are you thinking of building or adding a patio in your backyard? If so, you may have wondered which type of deck to choose. 

When choosing a decking, most people will agree that the lifespan is one of the most important deciding factors. 

For this reason, many people choose composite decking. But how long can it last compared to other types of decks? 

Composite Decking Lifespan

Different types of composites have various lifespans. Composite decking should last for at least 25 years. However, older generations of composite decking materials last shorter than the newer ones. 

Fortunately, most composites circulating in the market are of the latest production. Another indication of how long a deck should last is its warranty. 

Most companies offer at least 25 years of warranty. Some even give 30 years. Even if your composite decking doesn’t last as much as its warranty, you can be sure that you have a cheaper way of replacing it.

How does Composite Decking Compare to Other Decking?

How is it compared to other types of decking? First, let’s compare it with timber. Like composites, different types of wood have various lifespans. 

For the cheapest kinds of timber expect that it can last between 10 to 15 years. Aside from softwoods, there are also slightly more expensive hardwoods, which can last for at most 25 years. 

The most expensive types of timber, which are from exotic, top-quality hardwoods, can last for more than 25 years. 

So when compared to wood, composites can last twice as much as softwoods. It can last longer than hardwoods, but not the exotics ones. 

However, be prepared to pay a little bit more for exotic hardwood, like Ipe, compared to composites. 

Another popular choice when it comes to decking is PVC or all-plastic decking. How long does it last? 

Plastic decking has very similar lifespan to composites, which is around 25 to 30 years. They also have similar price ranges. However, they both have advantages and disadvantages that set them apart. 

Can Composite Decking Last Long?

You may have wondered, can composite decking really last for 25 years or more? Yes, it can. Some manufacturers even say that it can last for up to 50 years. Why so?

Composite decking materials have properties that make it last longer than your usual types of decking. One of the most common properties of composite materials is its capping. 

Composites have a plastic layer that covers the boards, usually except the bottom layer. 

With this protection, the materials become resistant to moisture damage, which is one of the worst problems that can considerably shorten a wooden decking’s lifespan. 

Another advantage of composite decking is its ease of maintenance. Without regular maintenance, a deck’s lifespan can significantly decrease. 

Because most wood is more high-maintenance than plastic or composites, which is more prone to neglect. 

You’ll need to sand, stain, and seal it every few years to protect it from damage from the elements. Not doing so can damage the deck over time. 

As for composites, it’s relatively easier to clean and maintain than wood. You only need to thoroughly wash it at least twice a year and minimal cleaning every few weeks. 

Advantages of Plastic-Wood Decking

Aside from the ease of maintenance and the long lifespan, composite decking has other advantages over wood and plastic.

 Compared to wood, composite decking doesn’t fade.

How long does composite decking last?

Granted, many people love the look of weathered wood. However, as over time, the colour of the board will fade into grey.

 As for composites, it will not turn to grey. It will only slightly lighten the boards. There are many other advantages of composite decking over wood and composites. 

Overall, choosing to build a decking out of composites is a solid choice. Granted, there are also a few advantages of using wood and plastic.

 But if you want a low-maintenance and non-fading decking that can last for decades, composite decking is an excellent choice. 

Also, it doesn’t warp or break when exposed to the heat of the sun not will it absorb water if it spills on it.


Composite decking is made to last long. It is unlike wood decking that will not last long. Some manufacturers give up to 30 years warranty for their decking.
