What Factors Affect Deck Restoration Costs in Sydney?
1. Deck Size
Most Sydney deck restoration services are priced per square metre. Expect to pay between $30 to $80 per m² for sanding and oiling, depending on the timber type and product used. Larger decks often have a lower cost per m² due to economies of scale.
2. Timber Type
Different timber species require different products and techniques, which affects cost. Hardwoods like Merbau and Spotted Gum are typically more expensive to treat than treated pine decks, requiring premium penetrating oils and additional sanding passes.
3. Current Condition
A deck in poor condition costs more to restore. Heavy weathering, mould growth, rotted boards, or multiple layers of old coating all add time and materials to the job. Early maintenance is always cheaper than full restoration.
4. Location in Sydney
Coastal suburbs like Bondi, Manly, and Cronulla may attract slightly higher pricing due to the additional protection required against salt air. Inner-city locations may carry access surcharges for tight-access properties.
5. Accessibility
Ground-floor decks are easier to access and cost less. Elevated decks, decks on steep blocks, or decks requiring scaffolding will cost more to service safely.
