Christchurch’s Seasonal Weather Threats to Homes
| Season | Typical Weather | Threat to Homes |
|---|---|---|
| Winter | Frost, rain, snow | Moss, mould, freezing damage |
| Spring | Rain, strong winds | Algae growth, debris buildup |
| Summer | High UV exposure | Paint fading, cladding drying |
| Autumn | Windstorms, heavy rain | Blocked gutters, wall staining |
✅ Each season creates unique exterior challenges — and builds up damage unless properly maintained.
What Happens When You Don’t Wash Your House Regularly?
1. Moss, Mould, and Algae Take Over
In humid winters and springs:
- Algae stains walls green and black
- Moss traps moisture on timber and plaster
- Mould spores threaten indoor air quality
✅ Regular soft washing removes spores before they penetrate surfaces.
2. Paint Breaks Down Under UV Attack
In hot Christchurch summers:
- Dirt layers amplify sun exposure
- Paintwork cracks, fades, and peels
- Timber and plaster dry out and crack
✅ Clean, dirt-free surfaces reflect UV better, preserving paint life longer.
3. Water Damage Around Windows and Trim
Storm seasons dump:
- Heavy rain
- Flying debris
- Contaminants into corners and joins
Result:
Water sneaks past dirty, compromised seals into walls.
✅ Washing clears buildup and highlights any early seal failures for fast repair.
4. Increased Pest Problems
Moss, mould, and algae create perfect homes for:
- Termites
- Ants
- Cockroaches
- Spiders
✅ Keeping your home’s exterior clean keeps pests out — naturally.
Why Soft Washing is Essential in Christchurch
✅ High-pressure water damages:
- Timber weatherboards
- Plaster systems (EIFS)
- Brick pointing and mortar
✅ Soft washing uses:
