Composite Decking vs Timber Decking Perth: The Complete 2026 Guide
Composite Decking vs Timber Decking Perth: The Complete 2026 Guide
One of the biggest decisions Perth homeowners face when planning an outdoor renovation is choosing between composite decking and timber decking. Both have their strengths, and the right choice depends on your priorities. In this guide we compare every aspect to help you decide.
Upfront Cost Comparison
Timber decking typically costs $80-$160 per square metre for materials, making it the more affordable upfront option. Composite decking ranges from $120-$250 per square metre. Popular timber species in Perth include Merbau, Spotted Gum, and Jarrah. Composite brands like ModWood and Futurewood offer a range of colours and finishes.
Lifetime Cost Analysis
While timber is cheaper to install, the long-term costs tell a different story. Timber decking requires oiling or staining every 12-18 months in Perth climate, replacement of weathered boards every 10-15 years, and ongoing maintenance. Composite decking requires no painting, staining, or sealing and typically carries a 25-year warranty.
Aesthetic Comparison
Timber offers natural beauty, unique grain patterns, and authentic warmth that composite cannot fully replicate. It weathers to a natural silver-grey if left untreated, which many homeowners love. Composite has improved dramatically in recent years with realistic wood-grain embossing and a wide range of colours from warm browns to cool greys.
Perth Climate Performance
- Heat: Dark-coloured composite can get hotter than timber underfoot in summer
- UV: Modern composite resists fading well; timber will naturally silver
- Moisture: Composite is impervious to moisture; timber needs proper sealing
- Termites: Composite is termite-proof; timber requires treatment
Installation Considerations
Composite decking uses hidden fastening systems for a clean finish but requires specific substructure spacing. Timber decking uses traditional screws and is more forgiving for DIY installation. Both require proper ventilation and drainage underneath.
Our Verdict
Choose composite decking if you want a low-maintenance outdoor area that will look great for decades. Choose timber decking if you love the natural look and dont mind the annual upkeep. Many of our customers choose composite for high-traffic areas and timber for garden settings.
