Deck builders in Northern Beaches— see your deck before you build it
Salt air is the defining factor from Manly to Palm Beach — coastal decks need stainless or heavily galvanised fixings and species that handle constant moisture cycling. Pool surrounds and beach-house entertaining decks dominate, and composite has grown fast here because it shrugs off salt spray without yearly oiling.

AFTERWhat decking costs in Northern Beaches
Composite — the most popular choice in Northern Beaches renders — runs $200–$350/m² installed (Sydney metro, including subframe). A typical 20m² deck lands between $4,000 and $7,000. Restoring an existing structurally sound deck costs roughly a third of a rebuild.

What decking lasts best near the beach?
Capped composite or dense hardwoods like ironbark handle salt exposure best. Whatever the boards, insist on marine-grade (316 stainless) fixings within a kilometre of the surf.
How often does a timber deck need oiling on the Northern Beaches?
Every 9–12 months in exposed coastal positions — roughly twice as often as inland. Composite eliminates this, which is why it's the most-requested material in our Beaches renders.
