One of the most common questions Brisbane homeowners ask is: how often should I have the outside of my house washed? For most Brisbane homes, the answer is at least once a year, and often twice.
Why Brisbane Homes Get Dirty Faster
Brisbane’s subtropical climate is perfect for mould, algae, mildew, and lichen growth. The combination of high humidity, warm temperatures year-round, and heavy summer rainfall creates ideal conditions for organic growth on exterior surfaces. Homes in areas with significant tree coverage, south-facing walls with limited sunlight, or near water tend to accumulate growth faster.
Recommended Cleaning Frequency
House exterior (walls, cladding, eaves): Every 12-18 months for most Brisbane homes. Twice per year for homes in high-humidity areas or with persistent mould issues.
Roof: Every 2-3 years for tile roofs. More frequently if you notice significant lichen or moss growth.
Driveways and paths: Every 12-24 months depending on foot traffic and surrounding vegetation.
Fences and decks: Annually, especially timber surfaces which are more susceptible to mould growth.
