Hamilton’s mix of rainfall, humidity, and pollen-rich air creates the perfect environment for exterior grime to thrive. Homeowners across Flagstaff, Hillcrest, and Glenview are seeing it firsthand — black mould on weatherboards, algae on soffits, and dust caked onto windowsills.
If your exterior is starting to look tired, it’s time to call in the soft washing experts at Metro Water Blasting.
What’s Coating Your Hamilton Home?
In just a few months, Hamilton’s environment can create serious buildup on your exterior:
- Algae and lichen feeding on shaded or damp cladding
- Black mould appearing on southern walls and trims
- Pollen and dust accumulating on gutters and window sills
- Spiderwebs and insect stains around eaves and lights
- Oxidation causing surface dullness on lighter exteriors
Not only do these affect appearance — they speed up paint degradation and create potential health risks.
Soft Wash vs. High Pressure: What’s the Difference?
High-pressure water blasting may seem like a quick fix, but it can:
- Crack weatherboard
- Strip paint and plaster
- Force water behind cladding
- Shorten the life of your exterior
That’s why we use low-pressure soft wash technology:
- Gently lifts grime and growth
- Uses biodegradable detergent
- Targets mould at the root
- Safe on timber, brick, Colorsteel, concrete, and plaster
Suburb-Based Cleaning Across Hamilton
We tailor every wash to the specific environment of each Hamilton suburb.
Flagstaff, Rototuna & Huntington
Modern homes with flat cladding and sharp trims need low-pressure detail work. We treat webs, oxidation, and pollen buildup without damage.
Hillcrest, Claudelands & Silverdale
Tree-heavy, shaded zones = high mould and mildew risk. We increase treatment dwell times and gently rinse paint to preserve it.
Nawton, Dinsdale & Grandview Heights
These exposed areas attract traffic grime and dust. We focus on surface restoration and edge detailing.
Glenview, Melville & Deanwell
In the south, homes are often mossy or green-streaked. We soak, rinse, and remove organic matter safely and thoroughly.

Hamilton Homeowner Feedback
“Metro came to clean our place in Claudelands. There was so much mould on the back wall I thought we’d need to repaint. Turns out we just needed a proper soft wash. Amazing difference!”
