When to Wash Your Home in NZ (Seasonal Guide)
New Zealand’s weather patterns play a big role in how often you should wash your home.
Here’s a simple guide to help you choose the best time for exterior cleaning in 2025.
1. Best Time of Year: Late Spring to Early Autumn
The ideal window for house washing is October to April.
During this period:
- Surfaces dry faster
- Mould and algae are easier to remove

This is also the most popular time to prepare homes for summer gatherings or for sale.
2. Homes Near Trees or Damp Areas
If your home is:

- In a humid area
…you may need cleaning more often. These homes tend to build up:

Annual cleaning is recommended.
3. Coastal or High-Rain Areas
Properties in places like:
- Auckland
- Tauranga
- Mount Maunganui
- Hamilton’s river-adjacent suburbs
…often face salt spray, humidity, and consistent moisture.
These conditions accelerate algae and mould growth.
Recommended frequency:
Every 12–18 months for best results.
4. Preparing to Sell or Repaint
If you’re selling or refreshing your home:
- A house wash instantly boosts curb appeal
- Roof treatments help remove visible discolouration
- Clean surfaces help paint adhere better
Pre-sale house washing is one of the highest-ROI maintenance tasks in NZ.
5. After Storms or Heavy Rainfall
If branches, debris, or silt collect around your property, it’s worth checking:
- Gutters
- Roof areas
- Lower walls
- Hard surfaces
A quick clean helps prevent long-term staining and water damage.
