At a Glance
Summer is winding down, and you have noticed the merbau deck is looking grey and dry after a season of barbecues. Or the back fence is peeling and the neighbours are starting to comment. Deck and fence painting in Sydney costs $500–$3,000 per job, and the condition of the timber is what really determines where you land in that range.
What's Included in the Price
- Cleaning: pressure wash or chemical clean to remove dirt, mould, and old coating residue
- Sanding: light sand for re-coating, or heavy sand for weathered and peeling timber
- Application of oil, stain, or paint per AS/NZS 2311 recommendations
- Two coats for bare or stripped timber; one coat for maintenance re-oiling
- Clean-up
For hardwood decks (merbau, spotted gum), the oil or stain product itself can be a meaningful portion of the cost. Premium decking oils designed for hardwood penetration are more expensive than general-purpose products.
What Affects the Cost
- Timber type. Hardwood decks in Sydney's eastern suburbs (merbau, spotted gum, ironbark) need specific oil products designed for dense timbers. Treated pine in newer suburbs absorbs standard products more readily.
- Condition. A deck that gets a maintenance re-oil every 12–18 months is a quick job. A deck that has been neglected for 3+ years with grey, weathered timber needs serious prep: heavy sanding or chemical stripping to remove the dead surface layer.
- Product choice. Oil (natural look, annual re-coat) vs stain (coloured, 2–4 year life) vs paint (longest lasting, hardest to maintain long-term). Your choice affects both the initial cost and ongoing maintenance.
- Fence complexity. Paling fences with narrow gaps are slow to paint. Both sides double the work. If the fence backs onto a neighbour's garden with overgrown plants, access adds time.
- Surface area. A compact courtyard deck (10–15m²) is a fraction of a large entertainer's deck (40–60m²). Long side fences can have more surface area than you expect.
- Salt exposure. Coastal areas (Bondi, Manly, Cronulla) need marine-grade products that resist salt spray.
A small deck re-oil on timber in good shape in Ryde sits toward $500. A large merbau deck in Coogee needing a full strip-and-restain plus 20 metres of paling fence on both sides pushes toward $3,000.
Sydney-Specific Considerations
Eastern suburbs hardwood decks. Suburbs like Randwick, Coogee, Bronte, and Maroubra are full of merbau and spotted gum decks. These hardwoods look fantastic when oiled but turn grey within months if maintenance is skipped. The key is a regular oil cycle: clean, light sand, oil. Once you let it go too long, the restoration cost is significantly more than the maintenance cost would have been.
Compact urban backyards. Many inner-city Sydney homes (Surry Hills, Newtown, Marrickville) have small courtyards rather than large yards. Deck areas tend to be compact (10–20m²), which keeps the total cost down, but minimum charges still apply. Fence painting in these areas benefits from shorter fence runs.
Salt air on coastal decks. Any deck within a few kilometres of the coast faces accelerated degradation from salt spray. Standard decking oils wash out faster, and timber fibres break down more quickly. Marine-grade or salt-resistant decking oils and stains are worth the premium. Ask your painter what product they recommend for coastal application.
Access. Sydney's inner-city blocks can have limited side access for bringing in equipment. If the painter needs to carry everything through the house, factor that into the job timeline. Rear fences on sloping blocks (common in the lower north shore and eastern suburbs) can also present access challenges.
Hiring a Licensed Painter in NSW
In NSW, painting work over $5,000 (including GST) requires a licensed painting contractor. You can verify credentials through NSW Fair Trading. Most standalone deck or fence jobs fall below this threshold, but combined deck-and-fence work can exceed it.
Regardless of whether a licence is legally required, always check:
- Public liability insurance
- A written quote specifying product brand, number of coats, prep scope, and what is excluded
- Experience with your specific timber type (hardwood and treated pine need different approaches)
Red flags: recommending a coat of oil on grey, weathered timber without sanding first (the oil will not penetrate), using a generic product on hardwood, or pressure washing softwood decking at high pressure (damages the timber fibres).
