Composite Decking vs Timber Decking Sydney – Complete NSW Comparison
The debate between composite decking and traditional timber decking is one of the most common decisions Sydney homeowners face when building a new deck or considering a major restoration. This guide compares both options honestly for NSW conditions.
What Is Composite Decking?
Composite decking is manufactured from a mixture of recycled wood fibres and plastic polymers. It’s designed to look like timber while requiring less maintenance. Popular brands in Australia include Trex, Ekodeck, and Titan Decking.
Composite vs Timber Decking – Sydney Comparison
| Factor | Composite Decking | Timber Decking |
|---|---|---|
| Initial Cost (installed) | $150–$350/m² | $50–$120/m² |
| Ongoing Maintenance | Very low (clean only) | Medium (oil every 1–3 years) |
| Lifespan | 25–30 years (non-repairable) | 30–50+ years (fully restorable) |
| Heat Retention (Sydney) | Can get very hot (40–60°C+) | Moderate (stays cooler) |
| Aesthetics | Uniform, plastic look | Natural beauty, unique grain |
| Environmental Impact | Contains plastic polymers | Natural, renewable (if certified) |
| Repairability | Difficult/impossible to repair | Fully repairable and restorable |
Why Most Sydney Homeowners Still Choose Timber
Despite composite decking’s marketing claims, the majority of Sydney homeowners with existing decks choose timber for good reasons:
- Heat performance: In Sydney’s summer (especially Western Sydney), composite decking can reach temperatures of 60°C+ — too hot to walk on barefoot
- Natural aesthetics: Timber’s natural grain variation cannot be replicated by composite products
- Long-term value: A properly maintained hardwood timber deck lasts 40–60 years; composite decking is non-restorable and must be fully replaced at end-of-life
- Property character: Sydney’s established homes — especially in the Eastern Suburbs and North Shore — are valued for their timber character
Restore Your Timber Deck — Don’t Replace It
Before you invest in composite decking, get a professional assessment of your existing timber deck. It may be far more restorable than you think.
