What a deck costs in Melbourne
Melbourne's reactive clay soils are the structural factor: deck footings have to be deep and designed for ground that moves with the seasons, or the deck shifts and the boards distort over time, so the substructure is where a Melbourne deck earns its cost. The cool, damp climate also weathers timber decking, and a timber deck here needs regular oiling and maintenance to survive the wet winters.
That maintenance burden is why composite decking, which does not need oiling, has grown strongly in Melbourne despite a higher upfront price, it trades material cost for years of upkeep. The deep local trade pool keeps planned work competitive. For a Melbourne deck, the footings the clay demands and the timber-versus-composite decision, driven by the climate, are the main cost factors.
