Sydney Composite decking
Premium Composite Decking Sydney | Low Maintenance Decks | Free Quote
Sydney homeowners love their outdoor spaces, but let’s be honest—the city’s harsh UV rays, sudden downpours, and humid summers can be brutal on traditional timber. Constant sanding, oiling, and worrying about splinters or rot is a commitment not everyone has time for.
Enter composite decking: the smart, modern alternative that gives you the timeless beauty of wood without the endless upkeep.
At Sydney Landscaping Pty Ltd, we specialize in designing and installing high-quality composite decks across North Ryde and the greater Sydney region. Whether you have a busy family, a pool area that needs slip-resistant surfacing, or simply want a beautiful outdoor space that stays perfect with just a hose-down, we have the solution.
With over a decade of local experience, we handle everything from initial design to council compliance, leaving you with a deck that looks spectacular today—and stays that way for decades.
Why Composite Decking? The Sydney Advantage
Traditional timber has its charm, but composite materials have evolved enormously. Today’s premium composites outperform wood in almost every category that matters to a Sydney homeowner.
Unmatched Durability
Composite decking is engineered to resist everything the Australian climate throws at it. It won’t warp, crack, rot, or become a feast for termites. Our boards are UV-stabilized to prevent fading, keeping their rich colour even after years of harsh Bondi-to-Penrith sun exposure.
Zero Sanding, Zero Oiling
This is the headline benefit. Once your composite deck is installed, you are done. No annual weekends spent with a sander and toxic sealants. A simple sweep and occasional wash with soapy water is all it takes to keep it looking brand new.
Splinter-Free and Slip-Resistant
For families with young children or pets, composite decking is a game-changer. There are no splinters, no raised grain, and no cracking timber. Plus, our boards feature textured, slip-resistant surfaces that meet Australian safety standards—perfect for pool surrounds and wet areas.
Eco-Friendly Choice
Many premium composite boards are made from recycled wood fibres and reclaimed plastic. By choosing composite, you are diverting waste from landfill and reducing the demand for old-growth timber.

Composite vs. Timber: The Honest Comparison
We love timber—it has a warmth that is hard to beat. But we believe in giving clients the full picture so they can make the right choice for their lifestyle.
| Factor | Composite Decking | Traditional Timber Decking |
|---|---|---|
| Initial Cost | Higher (350–600 per m²) | Lower (200–350 per m²) |
| Long-Term Cost | Lower (no oil, stains, or sealants) | Higher (annual maintenance products) |
| Maintenance | Sweep & wash only | Sand, oil, seal, repair every 1–2 years |
| Lifespan | 25–30+ years | 15–20 years (with diligent care) |
| Weather Resistance | Excellent (no rot, warp, or fade) | Moderate (requires protection) |
| Eco-Friendliness | Recycled materials | Natural but finite resource |
The bottom line: If you have a busy lifestyle, a pool, or simply don’t enjoy DIY maintenance, composite is the superior long-term investment.
The Sydney Landscaping Installation Process
Composite decking requires a different skill set than timber. It expands and contracts more with temperature changes, so proper spacing and hidden fastening systems are critical. Our team has mastered these techniques.
Step 1: Free In-Home Consultation
We visit your North Ryde or Sydney property to assess the site, discuss your vision, and measure for a precise quote. We answer all your questions about colours, railings, and budget.
Step 2: Custom Design & Approval
We create a 3D rendering of your proposed deck. If your deck is raised or requires council approval, we handle the Complying Development Certificate (CDC) process for you.
Step 3: Professional Sub-Frame Construction
Composite decks need perfectly level, robust substructures. We build using galvanised steel or treated pine joists spaced specifically for composite boards to prevent sagging.
Step 4: Precision Board Installation
We use hidden fasteners (clips) to attach each board, resulting in a screw-free, seamless surface. This also allows for the thermal expansion required for composite materials.
Step 5: Finishing Touches & Handover
We install fascia boards, stair nosing, and post wraps for a polished look. After a final clean, we walk you through care instructions (spoiler: it’s just soap and water).
Frequently Asked Questions (FAQ)
Q: Does composite decking get too hot to walk on in summer?
A: This depends on the brand and colour. Darker boards absorb more heat. We recommend lighter tones and brands like Modwood or NewTechWood, which are engineered to stay cooler. We can provide samples for you to test in your own backyard.
Q: Is composite decking slippery when wet?
A: No. All our composite boards feature textured, slip-resistant surfaces that meet Australian safety standards. They are actually less slippery than many oiled timber decks when wet.
Q: Can I install composite decking myself to save money?
A: Technically yes, but we strongly advise against it. Composite requires specific expansion gaps, hidden fasteners, and joist spacing. Improper installation voids the warranty and leads to buckling or sagging. Our installation comes with a workmanship guarantee.
Q: Does composite decking fade in the sun?
A: All materials fade slightly over time, but premium composites have UV stabilizers that significantly slow this process. Most brands offer a 25-year fade warranty, meaning any colour change is minimal and uniform.
Q: Do you service areas outside North Ryde?
A: Absolutely. While we are based in North Ryde, Sydney Landscaping Pty Ltd operates across all of Sydney, from the Northern Beaches to the Hills District and the Inner West.
Hidden Costs to Watch For (And How We Help)
Some composite deck quotes look cheap but hide essential extras. Here is what we include as standard:
Hidden Fasteners: Many builders charge extra for the clip systems. We include them.
Proper Joist Spacing: Composite needs joists at 300mm–400mm centres (not 450mm like timber). We do it right.
End Capping: Raw cut ends of composite boards can absorb moisture. We cap or seal every cut edge.
Thermal Expansion Gaps: Without proper gaps at walls and between boards, your deck will buckle in summer. We calculate every expansion joint precisely.
