When it comes to cleaning your home’s exterior, not all water blasting is created equal.
Many Auckland homeowners make the mistake of thinking “more pressure = better clean.”
In reality, high-pressure water blasting can seriously damage your home’s exterior — stripping paint, cracking plaster, and even forcing water behind your walls.

At Metro Water Blasting, we specialise in soft house washing Auckland services — a safer, scientifically better way to clean and protect your biggest investment.

Let’s dive into the science behind soft washing — and why it’s the smart choice for Auckland properties.

Auckland’s Harsh Environment and Your Home Exterior

Environmental Factor Threat to Your Home
Salt-laden coastal winds Corrode paint and expose surfaces
High UV exposure Cracks, dries, and fades exterior coatings
Heavy seasonal rain Traps moisture under dirty surfaces
Humid summers Accelerate mould and algae growth

✅ Proper cleaning isn’t optional — it’s essential maintenance for Auckland homes.

Why High-Pressure Washing Damages Auckland Homes

Surface High-Pressure Risk
Painted Weatherboard Paint stripping, water forced into seams
Brick and Mortar Cracked pointing, loosened bricks
Plaster/Render Hairline cracking, water ingress behind walls
Timber Cladding Grain splintering, rot acceleration
Joinery and Flashings Forced water breaches causing leaks

✅ High-pressure blasts attack the surface — soft washing treats the dirt, not the material.

How Soft Washing Works: The Science

Soft house washing uses:

  • Low-pressure water (lower than a garden tap)
  • Specially formulated biodegradable detergents that:
    • Break down organic growth (moss, algae, mould)
    • Loosen dirt, dust, and salt particles
    • Kill spores that would regrow

✅ Water acts as a rinsing agent, not a hammer.

✅ Chemical reactions do the heavy lifting — not brute force.

Science Fact: Surface Tension Matters

High-pressure jets increase surface tension, forcing water into cracks, holes, and seams.
Soft washing keeps water on the surface only, preserving:

  • Sealants
  • Paint
  • Structural integrity

✅ Protects your home from future rot, leaks, and repaint costs.

Real Damage We See from High-Pressure House Washing in Auckland

  • Flaking paint on homes under 10 years old
  • Water seeping into walls causing internal mould
  • Broken window seals leading to condensation issues
  • Faded and patchy paint jobs after one wrong clean
  • Erosion of soft mortar between bricks

✅ Most high-pressure mistakes cost homeowners $5,000–$20,000+ to fix.

Which Surfaces Need Soft Washing?

✅ Weatherboard cladding (painted or natural timber)
✅ Plaster and EIFS (solid or textured)
✅ Brickwork
✅ Concrete block exteriors
✅ Aluminium and timber joinery
✅ Outdoor furniture and fences

Bonus: Soft Washing Kills Harmful Organisms at the Root

Unlike high-pressure cleaning (which often just blasts dirt away temporarily),
soft washing uses biodegradable treatments that:

  • Penetrate biofilms
  • Kill algae, moss, and lichen at root level
  • Prevent fast regrowth

✅ Your home stays clean longer — and healthier.

Soft House Washing vs. High-Pressure: A Clear Winner

Factor Soft Washing High-Pressure
Surface Safety ✅ Safe for all surfaces ❌ Risk of damage
Organic Kill ✅ Yes (algae, moss, mould) ❌ No (only removes surface dirt)
Paint Protection ✅ Maintains paint life ❌ Strips or fades paint
Waterproofing Integrity ✅ Maintains seals ❌ Breaches seals
Cost of Repair ✅ None ❌ Expensive repairs likely

✅ Soft washing wins for long-term property protection.

How Often Should You Soft Wash Your Auckland Home?

Location Type Cleaning Frequency
Coastal homes (e.g., Mission Bay, Takapuna) Every 12 months
Urban/suburban homes (e.g., Epsom, Mount Roskill) Every 12–18 months
Heavily shaded homes (moss prone) Every 9–12 months

✅ Soft washing schedules preserve curb appeal and prevent expensive repainting.
