What a timber 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 timber deck is better value here for comparable scope. The main local factor is the coastal salt air, which greys and weathers timber and corrodes fixings in the beachside suburbs, so a durable hardwood like spotted gum or blackbutt and corrosion-resistant fixings are the sensible picks near the coast, where cheaper pine ages fast. The humid coastal climate adds to the weathering.
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. Moderate termite pressure means the frame should be treated or naturally resistant timber with proper clearance. The real long-run cost of timber here is the oiling the coastal weathering demands, so the lower build cost against composite is offset by upkeep. With the lower labour base, Newcastle is good value to build the deck.
