Perth’s stunning weather and abundant sunshine make clean windows a must for both homes and businesses. But how often should you clean your windows to maintain clarity, safety, and kerb appeal?
This depends on several factors including location, window type, local environment, and property use. In this guide, we’ll break down what affects your window cleaning schedule and how KBC Services can help you maintain sparkling results year-round.
Why Regular Window Cleaning Matters
Dirty windows don’t just look bad—they can also:
- Reduce natural light and energy efficiency
- Attract dust, allergens, and mould
- Lead to long-term etching or staining of glass
With Perth’s dry summers and occasional coastal winds, your windows are regularly exposed to dust, pollen, and salt spray—especially in suburbs like Joondalup or Fremantle. That’s why a consistent cleaning schedule isn’t just cosmetic—it’s essential maintenance.
Recommended Window Cleaning Frequency by Property Type
🏠 Residential Homes
Recommended: Every 3–6 months
For most homes in Perth, cleaning your windows every 3 to 6 months is ideal. Properties near construction zones or major roads—such as those in Morley or Malaga—may require more frequent cleaning due to higher dust levels.
Homes by the coast may need more attention as well. Salt buildup on glass can cause long-term damage if left unchecked.

🏢 Commercial Buildings
Recommended: Monthly or Bi-Monthly
Offices, retail stores, and showrooms often have higher visibility needs. Clean windows are crucial for maintaining a professional image and welcoming space for clients. Commercial properties in high-traffic suburbs like Belmont and Osborne Park benefit from regular monthly cleans to stay presentable and clear of pollutants.
We offer routine plans via our Commercial Window Cleaning Perth service.
🏢 High-Rise Apartments or Offices
Recommended: Every 2–4 months
Tall buildings are more exposed to windborne dirt and debris. Windows higher up collect fine dust quickly, even though they’re harder to reach. That’s why our High-Rise Window Cleaning Perth service ensures all levels—no matter the height—are safely and efficiently cleaned.
🧼 Internal Windows
Recommended: Every 3–4 months
While internal windows are less exposed to the elements, they can still collect fingerprints, cooking residue, and indoor pollutants. Areas such as kitchens and bathrooms benefit from more frequent cleaning to reduce moisture and prevent buildup.

🪟 External Windows
Recommended: Every 2–3 months
External windows take the brunt of Perth’s natural elements. Dust, insects, pollen, and salt quickly accumulate—especially in suburbs like Landsdale or Canning Vale. Keeping your external glass clean maintains visibility and protects your frames and seals from corrosion.
Our External Window Cleaning Perth solution is ideal for homes and businesses alike.
Factors That Affect Window Cleaning Frequency
- Location: Homes near busy roads or coastal suburbs get dirtier faster.
- Weather: Seasonal storms, bushfires, and wind increase debris buildup.
- Trees & Gardens: Properties with overhanging branches or lush gardens collect pollen, leaves, and sap.
- Pets & Children: Frequent fingerprints, nose smudges, and splashes make interior glass dirtier, faster.
- Construction Nearby: Dust and debris travel far and coat glass surfaces quickly.
Tips to Extend Cleanliness Between Services
- Wipe off fingerprints as they appear
- Trim back foliage and overhanging trees
- Install fly screens or window shields
