Timber vs. Composite Decking

We build decks in both traditional hardwood timber and modern composite decking, and we’ll help you choose the right material for your project:

• Hardwood timber — Species like Merbau, Spotted Gum, and Blackbutt offer natural beauty and durability. Timber decks need periodic oiling or sealing but are highly valued by buyers and blend naturally into garden settings
• Treated pine — A cost-effective decking option that takes stain or paint well and is suitable for most residential applications
• Composite decking — Low-maintenance boards made from recycled wood fibre and plastic. No oiling required, resistant to splintering, fading, and moisture, and available in a wide range of colours and finishes

Do I Need a Building Permit for My Deck?

In NSW, most decks under 1m in height and within certain size limits qualify as exempt development and don’t require a Development Application (DA). Decks over 1m high, attached to a heritage property, or exceeding the exempt threshold will require a DA or Complying Development Certificate (CDC). We can advise you on what approvals apply to your project during your free quote and help navigate the paperwork if needed.

Our Deck Building Process

2. Design & quote — We provide a detailed fixed-price quote with specifications for materials, dimensions, and finishes
3. Permits (if required) — We advise on and assist with any required approvals before commencing work
4. Footings & framing — Concrete footings are poured, posts set, and the sub-frame (bearers and joists) is built to engineering standards
5. Decking installation — Boards are fixed, spaced, and trimmed to create a level, even surface with a quality finish
6. Stairs, rails & finishes — Steps, handrails, balustrades, and any trim or fascia work is completed
