Timber decking
Comprehensive Maintenance Solutions
Nothing beats the natural beauty of a well-built timber deck. We work with a range of hardwood and softwood timber species to suit every budget and aesthetic.
All timber decking is treated, finished, and installed to Australian Standards with full compliance documentation provided.
Composite decking
Modernize Your Space
Composite decking is rapidly becoming the preferred choice for Sydney homeowners who want a premium, weather resistant decking installation that requires minimal upkeep. Unlike timber, composite boards don't warp, splinter, or require periodic oiling — making them ideal for coastal and high-traffic areas

Frequently Asked Questions
01
How much does a new deck cost in Sydney?
Deck pricing varies significantly based on size, material, and site conditions. As a rough guide we provide timber decking from $350/m² and composite from $400/m. We provide a free, itemised quote after visiting your property so you know exactly what to expect before committing.
03
Do I need council approval to build a deck in NSW?
It depends on the size and height of the proposed deck. Many standard ground-level decks are exempt from DA approval under the NSW Exempt Development provisions. Larger, elevated, or attached structures may require a Development Application or Complying Development Certificate. Bellwood Building Services will advise you on approval requirements during your free consultation and can manage the application process on your behalf.
02
What is the difference between timber and composite decking?
Timber decking offers natural warmth and beauty — species like Merbau, Spotted Gum, and Blackbutt are popular for their durability, though they require periodic oiling. Composite decking (Modwood, Ekodeck, Trex, Millboard) won't warp, splinter, or need oiling — ideal for coastal or high-traffic areas. Composite typically costs 15–25% more upfront but has lower ongoing maintenance costs.
04
How long does a deck build take?
A standard residential deck typically takes between 3 and 7 days to complete once materials are on site. Larger or more complex projects — including elevated decks, multi-level designs, or integrated pergola structures — may take up to 2–3 weeks. We provide a clear timeline in your written quote.
