The honest answer: less time than the paint tin suggests. Canberra is one of the hardest climates in Australia on exterior paint, and knowing the realistic lifespan helps you budget, plan and avoid the expensive mistake of leaving it too long.
Realistic lifespans in the capital region
As a general local guide, quality exterior paint properly applied lasts around seven to twelve years on weatherboard and cladding, ten to fifteen on rendered masonry, and five to eight on horizontal or high-exposure timber like handrails, pergolas and fascias. Budget paint or rushed preparation can halve those numbers. North and west elevations always age first; it is common for one side of a Canberra home to need attention years before the rest.
Why our climate is so tough
Three forces do the damage. First, ultraviolet: our clear skies and altitude give Canberra consistently high UV, which breaks down paint binders and fades colour. Second, movement: winter mornings below zero followed by sunny afternoons make timber and cladding expand and contract daily, cracking coatings that have become brittle. Third, frost and moisture: over a hundred frosts a year drive moisture into any gap in the paint film, then freeze and widen it. Coastal paint jobs simply do not face this combination.
The warning signs a repaint is due
Run your hand across the wall: a chalky powder residue means the paint has oxidised and stopped protecting. Look for fading that makes the home appear tired from the street, hairline cracking or flaking on trims and sills, timber that stays damp long after rain, and gaps opening at joints. Peeling is the late stage; by then, bare timber or render is exposed and deteriorating, and the eventual job costs more because repairs come before painting.
Catch it early and the maths improves
A repaint done while the old coating is merely tired is a straightforward job: wash, prepare, repaint. A repaint delayed three years past that point often involves replacing rotted fascia boards, extensive filling and priming bare surfaces, sometimes thousands of dollars of repair before a brush touches paint. The cheapest exterior repaint is the one done on time.
Making the next one last longer
Three things stretch lifespan in Canberra: preparation done properly rather than quickly, premium UV-stable topcoats specified for the surface, and application in the right conditions, which is why we schedule exterior coats around frosts and heat. It is also why our work carries a five-year workmanship warranty; when preparation and products are right, we can stand behind the result.

What a proper exterior repaint actually includes
Lifespan is decided before the topcoat goes on. A professional Canberra exterior repaint starts with a full wash-down to remove chalk, dirt and mould, then scraping and sanding of any failing paint back to a sound edge. Bare timber gets primed, cracks and gaps get filled and caulked, rusted fixings are treated, and damaged boards are repaired or replaced before painting, not painted over. Only then do two full topcoats of a premium UV-stable exterior system go on, applied within the product's temperature window. When you compare quotes, this preparation is usually the entire difference between prices, and it is the entire difference between a finish that lasts twelve years and one that fails in four.
