What a composite decking costs in Newcastle
Newcastle's deck builders charge below Sydney's while drawing on the same Hunter and Central Coast trade pool, so a composite deck is better value here for comparable scope. The main local case for composite is the coastal salt air, which greys and degrades timber in the beachside suburbs, where composite's salt resistance and low maintenance hold up far better. The humid coastal climate also drives the damp and mould that a timber deck suffers, which composite sidesteps.
The substructure depends on the ground, a mix of coastal sand and reactive clay, so the footings and frame cost vary with the site more than with the boards on top. Corrosion-resistant fixings and a protected frame are sensible near the coast whatever the surface. Composite's freight as a manufactured product adds a little to the material side as everywhere. With the lower labour base and the salt-resistance payoff, Newcastle is a good-value place to build the composite deck the coastal climate rewards.
