Dee Why is one of Sydney’s most sought-after coastal suburbs, and the demand for quality outdoor living spaces has never been higher. If you’re planning a deck renovation or new build in Dee Why, you’ll want expert builders who understand both the stunning beachside environment and the unique building requirements that come with it.
At 5 Star Decking, we’ve completed dozens of premium decking projects across Dee Why’s most prestigious properties — from clifftop residences with ocean views to contemporary homes near the beach. Here’s what sets our Dee Why decking service apart, and why property owners in this suburb trust us for their outdoor renovations.
Why Dee Why Homeowners Choose 5 Star Decking
Dee Why presents unique challenges for deck builders. The suburb sits on elevated terrain with significant coastal exposure — meaning salt spray, strong Pacific winds, and intense UV from reflection off the ocean. Your deck needs to be built tough.
We’ve spent years perfecting our approach to Dee Why decks:
- Salt-resistant materials: We prioritise composite decking (Evalast Pioneer, Modwood) and pressure-treated hardwoods that won’t corrode in the coastal climate.
- Elevated structural engineering: Wind-resistant footings, reinforced joists at 400mm centres, and proper drainage to handle Sydney’s summer storms.
- Ocean-view design: Low-profile railings, glass balustrades, and open-plan layouts that preserve your deck’s sightlines to the water.
- Year-round durability: Anti-slip surfaces for wet conditions, UV-stable finishes, and materials rated for 20+ years of coastal exposure.
Dee Why Decking Materials: What Actually Works in 2026
Material choice is everything in a coastal suburb. Here’s what we recommend for Dee Why properties:
Composite Decking (Best for Low Maintenance)
Evalast Pioneer — $150–$180/m² installed. GFR core, zero-maintenance, P4 slip rating, 25-year warranty. Ideal for salt spray zones. No oiling, no rot, handles coastal weather without fading.
Modwood — $140–$170/m² installed. Australian composite, excellent colour retention, thermal-resistant (stays cool in summer heat). Perfect for Dee Why’s intense sun.
Pressure-Treated Pine (Budget-Friendly)
C24 Grade — $80–$120/m² installed. Chemically treated for salt resistance, requires oiling every 12–18 months, but delivers classic timber warmth at a lower price point.
Hardwood (Premium, Natural Appeal)
Spotted Gum or Merbau — $180–$250/m² installed. Naturally durable, stunning grain, but demands regular maintenance (oiling) and higher upfront cost. Worth it for luxury properties with ocean views.

Dee Why Council Requirements: What You Need to Know
Building in Warringah Council (Dee Why’s local authority) has specific deck regulations:
- Height clearance: Decks over 1m high require council approval and building certification.
- Setback rules: Minimum 1.5m from property boundaries (more for corner blocks).
- Stair compliance: If your deck has stairs, handrails must meet AS 1200 standards (100mm sphere rule for spindle gaps).
- Footprint limits: Decks covering more than 10% of the block may trigger planning approval.
- Coastal protection zones: Dee Why has strict vegetation protection rules — we’ll navigate these for you.
We handle all council submissions and certifications — you don’t need to stress about red tape.
Why Coastal Decks Fail — And How We Prevent It
We’ve seen countless poorly built decks fail in Dee Why. Here’s what we do differently:
Problem: Salt spray corrodes steel fasteners.
Our solution: 316-grade stainless steel bolts and hangers throughout — zero rust risk.
Problem: Wood rots from poor drainage under the deck.
Our solution: 150mm ground clearance, gravel base, and membrane underlay to prevent moisture buildup.
Problem: Composite decking fades and discolours in intense sun.
Our solution: Premium UV-stable composites (Evalast Pioneer) that retain colour for 15+ years.
Problem: Wet, slippery surfaces create safety hazards.
Our solution: P4-rated anti-slip finishes on all boards, plus proper pitch (5mm/m) for water runoff.
