Finding a reliable exterior cleaning company isn’t just about price — it’s about trust, experience, and understanding how local environments affect your home. Across New Zealand, different regions face very different exterior cleaning challenges, from coastal salt spray and high humidity to inland dust, wind exposure, and heavy rainfall.
At Metro Water Blasting, we provide professional house washing, soft washing, water blasting, roof cleaning, gutter cleaning, deck cleaning, driveway cleaning, and exterior maintenance services across multiple locations nationwide. Each region we service has its own climate conditions, housing styles, and maintenance needs — and our approach is tailored accordingly.
This guide explains how exterior cleaning requirements vary across New Zealand, what services homeowners commonly need in each region, and how to get a fast, no-obligation quote for your property.
Why Location Matters for Exterior Cleaning
No two regions in New Zealand are the same. Exterior surfaces react differently depending on:
- Coastal exposure
- Humidity levels
- Wind patterns
- Tree coverage
- Rainfall frequency
- Housing density
- Age of homes and cladding types
A professional exterior cleaning service must adapt methods for each location to avoid damage and deliver long-lasting results.
Exterior Cleaning Services Available Nationwide
Across all regions, we offer a complete range of exterior cleaning services, including:
- House washing and soft washing
- Roof cleaning and roof moss treatment
- Gutter cleaning and downpipe flushing
- Water blasting for driveways, paths, and patios
- Deck cleaning (timber and composite)
- Fence cleaning
- Exterior mould and algae removal
- Full exterior cleaning packages
Each service is delivered using the correct pressure, safe detergents, and proven methods for the specific surface and environment.
Exterior Cleaning in Coastal & High-Humidity Regions
Homes near the coast or in high-humidity regions experience faster exterior deterioration due to salt spray, moisture retention, and biological growth.
Common Issues in Coastal Areas
- Salt residue on cladding and windows
- Accelerated paint fading
- Corrosion on metal surfaces
- Algae growth on shaded walls
- Slippery concrete and paths
Recommended Services
- Annual house washing (soft wash)
- Regular gutter cleaning
- Roof treatments to control moss and lichen
- Driveway and pathway water blasting
Routine cleaning in these regions prevents early repainting and long-term damage.
Exterior Cleaning in Wind-Exposed Regions
Wind-exposed areas push contaminants deeper into surfaces. Dirt, salt, pollen, and pollution don’t just settle — they are forced into cladding, roof lines, and window seals.
Common Issues
- Stubborn grime on walls
- Salt staining around windows
- Faster mould regrowth
- Debris buildup in gutters and valleys
Recommended Services
- Soft washing with proper dwell time
- Roof treatments rather than aggressive washing
- Frequent gutter maintenance
- Exterior trim and soffit cleaning
Using the wrong pressure in windy regions often leads to water intrusion, so correct methods are essential.
Exterior Cleaning in Inland & Rural Regions
Inland areas and regions surrounded by farmland or open land face different challenges.
Common Issues
- Dust and fine debris buildup
- Pollen accumulation
- Algae on shaded walls
- Dirty driveways and patios
Recommended Services
- Annual house washing
- Water blasting for concrete surfaces
- Deck and fence cleaning
- Gutter cleaning to remove organic debris
Dust and pollen embed into textured surfaces if not cleaned regularly.
Exterior Cleaning for Older Homes
Many regions include older housing stock with:
- Weatherboard cladding
- Aged paint systems
- Older gutters and downpipes
- Timber decks and fencing
These homes require gentler cleaning methods and experienced handling.
Best Practices
- Low-pressure soft washing only
- Avoiding high-pressure roof cleaning
- Careful deck and timber washing
- Preventative maintenance scheduling
Older homes benefit greatly from consistent exterior care.
Exterior Cleaning for Modern Homes
Newer homes often feature:
- Fibre cement or plaster cladding
- Modern paint coatings
- Aluminium joinery
- Decorative concrete and paving
While durable, these materials still need maintenance.
Common Issues
- Pollution film buildup
- Algae in shaded areas
- Driveway staining
- Gutter overflow from roof debris
Professional cleaning protects warranties and preserves appearance.
Why Bundled Exterior Cleaning Services Make Sense
Many homeowners across all regions choose to bundle services to save time and money.
Popular Combinations
- House washing + gutter cleaning
- House washing + driveway water blasting
- Roof treatment + gutter clean
- Full exterior clean (roof, house, gutters, concrete)
Bundling reduces labour duplication and ensures the entire property is maintained consistently.
How Often Should Exterior Cleaning Be Done?
While frequency varies by location, general guidelines apply nationwide:
- House washing: once per year
- Gutter cleaning: every 6–12 months
- Roof treatment: every 2–3 years
- Driveway & path cleaning: every 12–24 months
- Deck cleaning: every 12–18 months
Homes in coastal, shaded, or tree-heavy areas may require more frequent service.
Why Professional Exterior Cleaning Is Worth It
Professional exterior cleaning provides:
- Correct pressure for each surface
- Safe detergents and treatments
- Longer-lasting results
- Reduced risk of damage
- Improved curb appeal
- Protection of paint and cladding
- Prevention of costly repairs
DIY cleaning often causes surface damage, uneven results, and faster regrowth.
Signs Your Property Needs Exterior Cleaning
Look for:
- Green or black staining on walls
- Slippery driveways or paths
- Overflowing gutters
- Moss or lichen on the roof
- Dirty window frames
- Faded or dull exterior surfaces
- Cobweb buildup
If you notice any of these, it’s time to book a professional clean.
