What a timber decking costs in Canberra
Canberra's hard frosts, freeze-thaw cycles and the widest temperature range of any capital are tough on a timber deck, moving the boards, opening gaps and driving the damp that follows snow and frost, so a durable hardwood that holds its shape is worth the extra over treated pine in this climate. Whatever the species, a Canberra timber deck needs its oiling kept up, since the harsh cycle strips an un-maintained finish fast.
The substructure has to deal with frost in the ground and reactive soils in parts of the territory, so the footings are engineered beyond a mild-climate deck, and that cost is the same whatever boards sit on top. Canberra's high trade labour rates, among the dearest in the country, lift the framing and laying cost, and the smaller market keeps pricing firm. Timber is cheaper upfront than composite, but in Canberra's extremes the maintenance and board movement are a real part of the long-run cost.
