At a Glance
Deck and fence painting in Perth costs $500–$2,850 per job. Perth sits above eastern capital pricing partly due to a smaller trade pool, but also because Perth has a unique timber story: jarrah. Older Perth homes often have jarrah decks and pergolas, a local hardwood that responds to specific oil products better than generic alternatives. Colorbond fencing is increasingly common in newer suburbs, reducing the fence painting component.
What's Included in the Price
- Cleaning: pressure wash or chemical clean to remove dirt, dust, and old coating
- Sanding: light sand for maintenance, heavy sand for weathered or peeling timber
- Application of decking oil, stain, or paint per AS/NZS 2311 recommendations
- Two coats for bare or stripped timber; one coat for maintenance re-oiling
- Clean-up
Perth's dry, dusty conditions mean decks accumulate fine dust quickly. A thorough clean before coating ensures the product bonds to timber, not to a dust layer.
What Affects the Cost
- Timber type. Jarrah is Perth's local hardwood and appears on many older decks, pergolas, and outdoor structures. It is a dense timber that needs quality oil products for proper penetration. Treated pine is the standard for fencing.
- Heat constraints. Perth's extreme summer heat (40°C+) means deck coating must be applied in the early morning or evening during December to February. Midday application causes the product to dry too fast, preventing proper penetration into the timber. This extends job timelines in summer.
- Condition. Jarrah that has been regularly maintained with oil holds up well. Neglected jarrah goes grey and can develop surface cracking. Restoring neglected hardwood involves heavy sanding and multiple coats.
- Surface area. Perth homes tend toward generous outdoor areas. Decks of 30–50m² are common, and alfresco dining areas under roofed pergolas add more surface.
- Colorbond fencing trend. Newer Perth suburbs (Baldivis, Ellenbrook, Piara Waters) predominantly use Colorbond fencing, which does not need painting. Older suburbs with timber fences are the primary fence painting market.
- Product choice. For jarrah and other hardwoods, a penetrating oil is standard. For treated pine fences, an opaque stain or paint provides better UV and moisture protection.
A small deck re-oil on a well-maintained jarrah deck in Duncraig sits toward $500. A large deck restoration involving heavy sanding, multiple coats, plus a long timber fence repaint in an older Morley property pushes toward $2,850.
Perth-Specific Considerations
Jarrah decks (Subiaco, Mount Lawley, Morley, Kalamunda, Mundaring). Jarrah is Western Australia's iconic hardwood, and it has been used extensively for decking, pergolas, and outdoor structures in Perth for generations. When oiled and maintained, jarrah develops a rich red-brown tone. When neglected, it weathers to a silver-grey that can be attractive in some settings but indicates UV damage to the timber surface. Restoring neglected jarrah to its oiled appearance requires sanding back to fresh timber and 2–3 coats of penetrating oil.
Heat and application timing. Between December and February, Perth deck surfaces can reach 60°C+ in direct sun. Decking oil applied at these temperatures flashes off before penetrating, leaving a sticky residue that does not protect the timber. Professional deck painters in Perth work early (6am to 10am) during summer or schedule the work for autumn and spring. If you are booking a deck job, March to May or September to November are the ideal windows.
Older suburbs with timber fencing (Morley, Dianella, Bedford, Bayswater). These suburbs still have significant amounts of timber paling fencing. Without regular maintenance, Perth's dry heat and UV cause pine fences to crack, split, and grey within a few years. A coat of paint or opaque stain every 3–4 years significantly extends fence life.
Alfresco areas and pergolas. Perth's outdoor living culture means many homes have roofed alfresco areas with timber pergola structures. These need regular oiling or staining alongside the deck. Include them in the scope when getting quotes.
Coastal suburbs (Scarborough, Cottesloe, Hillarys, Fremantle). Timber near the coast weathers faster due to salt air. Decking oil on coastal properties may only last 8–10 months before needing re-application. Marine-grade or salt-resistant timber oils extend the interval.
Hiring a Licensed Painter in WA
Western Australia requires painting work over $1,000 to be done by a registered painting contractor through Building and Energy (DEMIRS). The low threshold means many deck and fence jobs require a registered painter.
Check before hiring:
- Current WA painting contractor registration
- Public liability insurance
- A written quote specifying product brand, number of coats, prep method, and what is excluded
- Verify registration via the Building and Energy register
Red flags: recommending a single coat of cheap oil on neglected grey timber (it will not penetrate), using standard interior products outdoors, or scheduling application during the heat of a Perth summer day. A good outdoor timber specialist works with the weather, not against it.
How We Calculate
Estimates are based on current registered Painter rates in the Perth metro area, adjusted for timber types and local conditions. All prices include GST. Figures cover standard residential deck and fence painting or staining. Structural timber repairs, new construction, and pergola construction are excluded.
