Fences are one of the most exposed parts of any property — constantly facing rain, sun, dirt, and organic growth. Over time, this leads to green staining, mould buildup, and a dull, weathered appearance.
Across Auckland, fences in both residential and commercial properties quickly lose their original look due to moisture and environmental exposure.
A professional fence clean not only restores appearance but also helps protect and extend the lifespan of your timber or painted surfaces.
Why Fence Cleaning Is Important in Auckland
Auckland’s climate creates the perfect conditions for fence deterioration.
With:
- High humidity
- Frequent rainfall
- Shaded outdoor areas
- Organic debris from trees
…fences become a breeding ground for:
- Moss
- Mould
- Algae
This buildup doesn’t just affect how your fence looks — it can also cause long-term damage if not treated properly.
Common Problems We See on Auckland Fences
Green & Black Staining
Caused by algae and mould, this is one of the most common issues.
Weathering & Fading
Exposure to UV and rain causes timber to fade and lose colour.
Dirt & Grime Buildup
Dust, pollution, and organic debris settle into the surface over time.
Slippery or Slimy Surfaces
Especially on shaded fences — a sign of algae growth.
Types of Fences We Clean
Different fence materials require different cleaning methods.
Timber Fences (Pine, Treated Timber)
Characteristics:
- Soft surface
- Absorbs moisture
- Easily damaged by high pressure
Correct Cleaning Method:
- Low-pressure wash
- Soft treatment to kill mould and algae
Important:
Using too much pressure can:
- Damage timber fibres
- Cause splintering
- Leave uneven surfaces
Painted Fences
Characteristics:
- Protected surface (painted coating)
- Sensitive to high pressure
Correct Cleaning Method:
- Soft washing
- Gentle pressure only
Risk of Incorrect Cleaning:

Hardwood Fences
Characteristics:
- Denser material
- More durable
Cleaning Approach:
- Controlled pressure

Even hardwood can be damaged if excessive pressure is used.
What Pressure Should Be Used?
This is one of the biggest misconceptions in fence cleaning.
👉 More pressure does NOT mean better results.
General Guide:
- Timber fences → Low pressure only

- Hardwood fences → Moderate controlled pressure
The key is combining:
- Correct pressure
- Proper technique
- Effective cleaning solutions
