Why More Homeowners Are Choosing Composite Decking: Upfront Costs Vs Long-term Savings

When planning a new deck, the choice of material can feel overwhelming. Timber decking has long been the go-to option, but in recent years, composite decking has gained popularity across Australia—and for good reason. While the initial cost may be slightly higher, the long-term benefits of composite decking can far outweigh traditional timber.

In this article, we’ll break down the key advantages of composite decking, its upfront and long-term costs, and what makes it such a smart investment for any homeowner looking to build a functional and stylish outdoor area.

What Is Composite Decking?

Composite decking is a man-made product crafted from a mix of recycled wood fibres and plastics. The result? A durable, eco-friendly alternative to natural wood that offers the visual appeal of timber without the ongoing maintenance.

There are two main types of composite boards:

• Uncapped composite decking – more affordable, but prone to moisture absorption and mould.

• Capped composite decking – sealed with a protective shell that improves resistance to moisture, fading, and staining.

Upfront Cost vs. Long-Term Value

It’s true—composite decking boards tend to have a higher initial cost than timber. Prices often range from $80 to $250+ per square metre, depending on quality and board type. In contrast, timber decking may cost between $90 and $150 per square metre.

But here’s the key: timber decking comes with recurring maintenance costs.

Ongoing Maintenance Costs for Timber:

• Annual sealing or staining: ~$10 per m² per year

• Repair costs from warping, rot, and splintering

• Labour or time for upkeep

Over 10 years, maintenance alone can add hundreds—if not thousands—of dollars to your decking investment.

Composite Decking Maintenance:

• Low maintenance – just a soap-and-water clean a couple of times a year

• No sanding, sealing, or staining

• Resistance to termites, mould, UV damage, and rot

In short, composite decking pays for itself over time, especially for homeowners who want to “set it and forget it.”

Durability That Withstands Aussie Weather

Australia’s climate can be harsh—strong UV rays, salty coastal air, and heavy rainfall all take a toll on outdoor materials. Unlike timber, composite decking:

• Won’t splinter or crack

• Won’t fade or warp as easily

• Lasts up to 30 years, depending on the product

Choosing a high-quality, solid composite board (not hollow core) is crucial for strength and longevity. At Sam Outdoor Living, we only work with trusted brands that deliver durability and performance. 

Eco-Friendly and Sustainable

One of the lesser-known benefits of composite decking is its sustainability. Most composite boards are made from recycled plastics and wood by-products, reducing landfill waste and promoting greener building practices.

If you care about environmental impact, composite decking is a great way to create a beautiful outdoor space without sacrificing sustainability.

Are There Any Downsides?

Like any material, composite decking isn’t perfect. Some things to be aware of include:

• Potential for mould growth if water is trapped in shaded or damp areas

• Slight fading over time, especially with cheaper products

• Warping can occur if not installed correctly or if poor-quality boards are used

These issues are usually avoidable with proper installation and selecting high-quality, capped composite decking from reliable suppliers.
