How Long Does Decking Last? Composite vs Aluminium vs Plastic vs Wooden
So you’re thinking of creating a decking in your garden or on your terrace? One thing you will want to know is how long it will last. This is an important factor when deciding on the material of your deck, as we’re sure you don’t want to spend more than necessary but have a decking that will last as long as you need it to.
In this article we will cover the lifespan of each of the three main materials, what affects the lifespan, and how you can make sure your decking area lasts as long as possible. This should help you to decide on what the best decking surface is for you.
Wooden Decking
Wooden decking lasts from 5-10 years in general. After this period moisture and rot will have affected it badly enough that it will need replaced. Moisture and rot are the biggest factor in affecting the lifespan of decking. In general, the damper the area, the less it will last. One way to improve how long a wooden deck lasts is to maintain it. Coating it every few months will help to squeeze an extra year or two out of it.
Composite Decking
Composite decking lasts from 20-30 years. The main factor that affects how long composite decking lasts is whether it is capped or not. Capped decking lasts longer due to the cap, this is usually made of HDPE or PVC plastic, and encapsulates half or the whole board, protecting it further from the elements. A PVC cap is higher performance and is even less likely to scratch.
A good guide would be that;
- An uncapped board lasts around 20 years
- A HDPE capped board lasts around 25-30 years
- A PVC capped board lasts around 30 years
Composite decking does not require much maintenance at all – just keep it from being submerged in water for very long periods of time, and make sure the subframe to strong and your composite decking is sure to last as long as the claimed!
Aluminium Decking
Aluminium Decking is a relatively new product; however, it is thought that it will last from 25-35 years. This is due to the fact that it will not rot and will retain its strength properties for a long time. One factor that can affect the lifespan of aluminium decking is the coating on the aluminium. This is a paint coating that is susceptible to scratching, which can become very noticeable as the billet aluminium will then show through. To keep an aluminium decking looking its best, you will have to touch it up with paint when a scratch is noticed.
Summary
So, aluminium and composite decking last the longest, and you will have to replace your timber deck the most often. Interested in knowing how much these materials cost? Check out our pricing article here, which will help you further decide what the perfect material is for your deck.
