What Affects the Cost
Weather and drying. Timber must be dry for 48–72 hours before coating. Melbourne's unpredictable rain means jobs can stall mid-process. Oil or stain applied to damp timber will not penetrate properly and can blister or peel within months. This weather dependency is why summer bookings fill fast.
Timber condition. Treated pine fencing weathers to grey in Melbourne's damp climate within 1–2 years. Weathered timber needs sanding back to fresh wood at $15–$27/m2 before any coating will adhere properly.
Surface area. Melbourne's eastern suburbs tend to have larger rear yards with longer fence runs and bigger decks. A 25-metre boundary fence at 1.8m height is roughly 90 m2 of paintable surface (both sides).
Fence height and type. Standard 1.8m treated pine paling fences are the most common. Merbau screen fences and horizontal slat fences take different products and application methods.
Number of sides. Painting both sides of a fence roughly doubles the labour. If the neighbour's side has overgrown garden beds, access adds further time.
Product choice. For treated pine fences,
Wattyl Solagard Deck & Timber Paint (~$20–$25/L, 25-year warranty) or Dulux Weathershield (~$19/L) provide solid colour coverage. For hardwood decks, a penetrating oil like
Cabot's Deck & Exterior Stain (~$31/L) or Intergrain UltraDeck (~$35/L) is the standard approach.
A small deck re-oil on a well-maintained merbau deck in Doncaster sits toward $500. A large treated pine deck strip-and-restain plus 25 metres of paling fence on both sides in Cranbourne pushes toward $3,000.
Melbourne-Specific Considerations
Outer suburb fencing (Cranbourne, Point Cook, Werribee, Berwick, Pakenham). Melbourne's growth corridors are fence country: long side and rear boundaries with standard treated pine paling fences. These fences go from green treated pine to grey and rough within a couple of years in Melbourne's damp conditions. Without coating, they start splitting and cracking within 3–4 years. A coat of paint or opaque stain every 3–4 years extends their useful life by decades. The labour is the dominant cost, because paling fences have gaps and rough surfaces that make each paling slow to coat individually. Budget $15–$20 per linear metre (one side) for straightforward fence painting.
Weather windows and scheduling. December through March gives the best chance of consecutive dry days. Autumn can work if you catch a dry spell, but drying times lengthen as temperatures drop below 15 degrees C. Avoid booking outdoor timber work from May through August: the timber may never fully dry between rain events, and any coating applied to damp timber is wasted money. A good painter will check the Bureau of Meteorology forecast and will not start a job if rain is expected within 48 hours.
Established eastern suburbs (Glen Waverley, Box Hill, Templestowe, Eltham). These suburbs have generous rear yards with mature gardens, established trees, and entertainment-sized decks of 30–50 m2. Fence runs are longer, and the total surface area can be surprisingly large when measured properly. Make sure your painter quotes based on measured area, not a visual estimate from the driveway.
Mould and algae on shaded surfaces. South-facing deck boards and fence palings in shaded parts of the yard are prone to green algae growth in Melbourne's humid winters. An oxalic acid wash or dedicated mould treatment ($50–$100 in product cost for a standard deck) is a necessary pre-treatment step. Coating applied over active mould guarantees adhesion failure within months, regardless of how good the product is.
Composite decking in newer estates. Many newer Melbourne homes use composite (non-timber) decking. Composite does not need oiling or painting in the traditional sense, though some products do fade over 5–10 years and can be rejuvenated with specialist composite treatments. If you have composite decking, confirm your painter has experience with the specific product, as standard timber coatings will not adhere to composite surfaces.
Hiring a Licensed Painter in VIC
Victoria has a single-trade exemption for painting, so painters doing painting-only work are not required to hold VBA registration. Most deck and fence jobs are painting-only work. If the job involves structural timber repairs (replacing rotted deck boards or fence posts), a registered builder may be required for that component.
A good outdoor timber painter will:
Inspect the timber in person before quoting
Specify the product brand and number of coats in writing
Schedule around Melbourne's weather and factor in drying days
Use a dedicated mould wash before coating (not just a pressure wash)
Worth checking:
That the painter includes a mould pre-treatment for any shaded surfaces (coating over active mould guarantees adhesion failure)
That the timber will be fully dry before coating begins (Melbourne's damp conditions mean longer drying times between wash and coat)
That the pressure washer setting is appropriate for softwood decking (high pressure damages fibres and raises the grain)
That the quote accounts for Melbourne's weather windows and includes drying days in the schedule
How We Calculate
Estimates are based on current Painter rates in the Melbourne metro area, adjusted for typical timber types and housing stock. All prices include GST. Figures cover standard residential deck and fence painting or staining. Structural repairs, new deck construction, and pergola work are excluded.
