Why Exterior Stains Are Worse in Tauranga
- Coastal Salt Spray: Wind off the Bay of Plenty carries salt that clings to cladding and glass.
- High Humidity: Promotes rapid moss, mould, and algae growth.
- Seasonal Storms: Bring dust, dirt, and plant matter that stain walls and roofs.
- Strong UV Rays: Fade paintwork and dry out timber, making surfaces more porous and stain-prone.
A once-beautiful home can quickly look worn and neglected without regular professional exterior house cleaning Tauranga services.
Most Common Exterior Stains Tauranga Homeowners Face
1. Salt Residue Stains
Where It Happens:
- Coastal properties like Papamoa, Mount Maunganui, and Te Puna.
What It Looks Like:
- White, chalky streaks across windows, doors, and cladding.
How Soft House Washing Helps:
- Gently dissolves and washes away salt deposits without damaging paint or timber.
- Protects surfaces from accelerated corrosion.
2. Green Algae Growth
Where It Happens:
- Shaded sides of houses, under eaves, behind trees and fences.
What It Looks Like:
- Slimy green patches on cladding, decks, paths, and roofs.
How Soft Washing Removes It:
- Specialized eco-friendly cleaning agents kill algae spores.
- Low-pressure rinsing clears surfaces without stripping paint or breaking seals.
3. Black Mould and Mildew
Where It Happens:
- Around gutters, under soffits, on weatherboards, especially in humid areas.
What It Looks Like:
- Black or grey splotches that spread rapidly.
How Professional House Washing Works:
- Treatments neutralize mould at the root, preventing regrowth.
- Full surface cleaning restores original appearance safely.
✅ Regular soft house washing Tauranga prevents interior mould problems by keeping exteriors dry and clean.
4. Red Dust and Soil Splash Stains
Where It Happens:
- Homes near construction sites, rural properties, or on busy roads like Cameron Road.
What It Looks Like:
- Reddish-brown streaks low on walls, particularly near ground level.
How We Remove It:
- Pre-treatment soaks dust stains.
- Low-pressure soft washing lifts dirt without scarring surfaces.
5. UV Fading and Surface Dryness
Where It Happens:
- All across Tauranga, especially homes facing north or west.
What It Looks Like:
- Faded, dry, cracked, or powdery paint.
How Washing Helps:
- Washing removes loose debris and salty residue that accelerate UV damage.
- Prepares surfaces properly for repainting if needed, extending the life of existing coatings.
Why DIY House Washing Often Makes Stains Worse
Using a hardware store water blaster or garden hose can:
- Drive dirt deeper into porous surfaces
- Damage delicate paints and wood grains
- Miss critical areas like gable ends, rooflines, and window trims
- Spread algae and mould spores without killing them
✅ Professional soft house washing treats stains at the source and preserves your home’s integrity.
