What a composite decking costs in Gold Coast
The Gold Coast combines everything that punishes a timber deck: pervasive salt air, intense UV and heavy poolside and waterfront use, so composite is the natural choice here for its resistance to salt corrosion, fading and the splitting and greying that timber suffers by the coast. Around pools and on canal-home jetwalks, composite's splinter-free, low-maintenance surface is a particular draw where bare feet and constant water make timber a chore to keep up.
The substructure still needs care: sandy coastal soils and canal-estate fill can settle under a deck frame, and the salt air means corrosion-resistant or hot-dip galvanised fixings and a protected frame whatever the boards. Labour tracks the South East Queensland market near Brisbane's, so composite work is reasonably priced, and termite pressure adds to the case for a non-timber surface. A UV-stable, quality board is worth specifying, since the strong coastal sun fades cheaper composite over time.
