Get connected with experienced deck builders across Perth. Compare timber and composite options designed for Perth's outdoor lifestyle and summer heat.
What Is Decking?
Decking creates an elevated or ground-level outdoor floor surface using timber boards or composite planks fixed to a structural frame. In Perth, decking is one of the most popular outdoor improvements -- it extends your living space, adds value to your home, and creates a seamless connection between indoors and outdoors.
Popular timber choices in Perth include merbau (durable, rich colour, mid-range price), jarrah (iconic WA native hardwood, premium), and treated pine (budget-friendly entry point). Composite decking blends recycled wood fibres and plastic for a low-maintenance alternative that handles Perth conditions well.

Perth-Specific Considerations
Summer heat performance: Perth decks get intense direct sun. Dark-coloured timbers can become uncomfortably hot -- consider lighter composite colours or pair your deck with a pergola or shade sail for afternoon relief.
Termite protection: Perth is in a high termite zone. Timber substructure should be H4-rated minimum, and a termite management system is recommended. Composite decking boards are termite-proof but the supporting frame still needs protection.
UV degradation: Perth's intense UV bleaches and cracks unprotected timber. Regular oiling with a UV-rated decking oil is essential for timber decks. Composite boards include UV stabilisers but can still fade over time.
Sandy soil footings: Perth sand requires concrete footings for elevated decks. Screw piles are a popular, efficient option in Perth sandy soils and avoid the need for traditional excavated footings.
