If you’re thinking about adding a new deck or replacing an old one, you’re probably wondering: how long does decking last? The answer depends on several factors – from the material you choose to how well it’s looked after. In this article, we’ll break down average lifespans by decking type, explain what affects durability, and share some tips to help your deck stand the test of time.
Average Lifespan of Decking Materials
Not all decking is made equal. Some materials naturally last longer than others, and each has its own pros and cons in terms of maintenance and cost.
uPVC Decking
uPVC decking is one of the longest-lasting options on the market today. On average, a good-quality uPVC deck can last 25 to 30 years, sometimes even longer with minimal maintenance. Because it’s made from plastic-based materials, it doesn’t rot, warp, or splinter like wood. It’s also stain and weather-resistant, making it ideal for UK climates with lots of rain and temperature changes.
Timber Decking
Traditional timber decking, particularly softwood, tends to have a much shorter lifespan. Expect around 10 to 15 years on average, depending on the type of wood used and how regularly it’s treated. Hardwoods like teak or oak can last longer – sometimes up to 25 years – but they still require regular care to prevent rot, mould, and insect damage.
Composite Decking
Composite decking, which combines wood fibres with plastic, usually lasts around 20 to 25 years. It offers better durability than softwood and doesn’t require as much maintenance. However, it may still fade over time or crack under extreme weather conditions.
What Affects ‘How Long Does Decking Last’?
The material is just one part of the story. Several other factors can impact how long your decking will hold up over the years.
Weather Exposure
Decking that’s exposed to constant rain, frost, or strong UV rays will naturally wear faster. uPVC decking is built to handle harsh weather, while timber may require regular sealing to cope.
Maintenance Routine
A well-maintained deck will always outlive one that’s been neglected. Timber needs regular cleaning, sanding, and sealing. uPVC and composite decking need far less maintenance, usually just an occasional wash to keep it looking fresh.
Installation Quality
Poor installation can lead to issues like water pooling, poor drainage, or unstable foundations. Choosing experienced installers ensures your decking is properly fitted and set up to last as long as possible.
Foot Traffic and Usage
High-traffic areas or spaces used for furniture and BBQs may wear down faster. Again, this is where tougher materials like uPVC come into their own – they’re built to take the strain of everyday use without cracking or fading.
Signs Your Decking May Need Replacing
Even the best decking materials eventually show signs of wear. Here are a few things to keep an eye out for:
- Splitting or cracking boards
- Loose or unstable decking underfoot
- Faded colour that doesn’t improve with cleaning
- Visible mould, rot, or warping
- Rusted or failing fixtures and fittings
If you spot any of these signs, it might be time to consider replacing part or all of your decking.
How to Make Your Decking Last Longer
While some wear and tear is inevitable, a few simple steps can help you extend your deck’s lifespan.
Clean Regularly
Dirt, leaves, and moisture can all lead to quicker degradation – especially for timber decking. A regular sweep and occasional wash will go a long way.
Check for Damage
Inspect your deck at least once a year, especially after winter, and fix any loose boards or screws as soon as you notice them.
Apply Sealants (for Timber)
Softwood decking needs protective coatings every year or two to stop water from soaking in and causing rot.
Choose Quality from the Start
Investing in high-quality, weather-resistant materials from the beginning – such as uPVC decking – can save you time and money in the long run.
Why uPVC Decking is the Longest-Lasting Choice
With its weatherproof properties, low maintenance needs, and long lifespan, uPVC decking is an excellent choice for holiday homes, garden decks, and park homes alike. It won’t crack or fade like wood, and it keeps its colour for years, even in full sun or heavy rain.
Plus, it’s 100% recyclable, making it a more eco-friendly choice than timber decking. And with plenty of colour and style options – including wood-effect finishes – you don’t have to sacrifice looks for durability.
So, How Long Does Decking Last?
To sum up:
- uPVC decking: 25–30 years or more
- Composite decking: 20–25 years
- Hardwood decking: 15–25 years
- Softwood decking: 10–15 years
Choosing the right material, installing it properly, and looking after it well can all add years to your deck’s life. For the best return on investment with the least hassle, uPVC decking is hard to beat.

FAQs
How long will uPVC decking last?
uPVC decking can last 25 to 30 years or more with very little maintenance. It doesn’t rot, warp or splinter like wood, and it’s fully resistant to weather, insects, and moisture, making it one of the longest-lasting options out there.
What can affect how long decking lasts?
The biggest factors are the type of material, how it’s installed, and how well it’s looked after. Timber needs regular treatments, while composite and uPVC need much less. Things like poor drainage, constant damp, or bad installation can all shorten your deck’s life.
When should I replace my decking?
If you’ve got loose boards, rotting timber, or the whole structure feels unstable, it’s probably time for a replacement. Most timber decking will need replacing after 15–20 years, while uPVC or composite can last much longer before showing signs of wear.
