Softwash Auckland — Safe, Low-Pressure Cleaning for Roofs and Buildings

High-pressure washing can strip paint, crack tiles, and force water behind cladding. Softwash does the same job — and often a better one — without the damage risk. We use biodegradable cleaning agents at low pressure to safely remove mould, algae, lichen, and organic staining from roofs, cladding, and facades across Auckland.

What Softwash Treats

The right method for biological growth and organic staining

Auckland's wet climate makes biological growth almost unavoidable. Softwash is the safest and most effective way to address it — whether it's appeared on a roof, a wall, or a deck.

Mould and mildew

Black and green mould on cladding, soffits, and external paintwork. Softwash kills the spores, not just the surface staining.

Algae and green staining

Green algae on roofs, concrete, and timber surfaces. Biodegradable algaecide breaks it down and prevents rapid re-establishment.

Lichen on roofs

Lichen attaches its rhizines into roofing material, causing surface degradation. Softwash treatment loosens and removes it safely.

Salt and mineral deposits

Coastal Auckland properties develop salt crust on surfaces. Regular softwash prevents salt from degrading painted surfaces and seals.

Atmospheric soiling

General grey-black staining from urban pollution and exhaust on facades and window frames. Cleaned back to base colour.

Moss on paths and decking

Slippery moss on timber decking, concrete paths, and steps. Safe softwash application removes the growth without damage to the surface.

Surfaces we softwash

  • Colorsteel and metal roofing
  • Concrete and clay tile roofs
  • Painted weatherboard and Hardie cladding
  • Brick and plaster building facades
  • Timber decking and pergolas
  • Concrete driveways and paving
  • Vinyl and aluminium window joinery
  • Fences, retaining walls, and boundary structures

How the softwash process works

01

Surface assessment

We identify the growth type, surface material, and any sensitive areas (gutters, gardens, glazing) before we start.

02

Chemistry application

Biodegradable treatment is applied at low pressure. Dwell time allows the chemistry to penetrate and kill biological growth.

03

Rinse and inspect

A thorough low-pressure rinse removes all residue. We inspect the result and spot-treat any stubborn areas before leaving.

Auckland Context

Why Auckland buildings need regular softwashing

Auckland's subtropical climate — warm, humid, and wet for much of the year — creates ideal conditions for mould, algae, and lichen to establish quickly. North-facing surfaces and those shaded by trees or adjacent buildings are particularly prone.

Salt-laden sea air affects coastal Auckland suburbs from Devonport to Beachlands. The combination of salt and moisture degrades paint and seals, and provides a base layer for biological growth to take hold faster.

Residential and commercial softwash

We softwash both residential properties and commercial buildings across Auckland. For residential, that's typically the full exterior — roof, cladding, gutters, and driveway in one visit. For commercial, we work section by section to minimise disruption.

Safety-first access

All roof and elevated surface work uses appropriate access equipment and PPE. We carry full public liability insurance for every job.
