Mould Removal & Soft Washing in Coffs Harbour
From
$300
Mould removal on a Coffs Harbour house exterior is done by soft washing rather than pressure cleaning, and starts from $300 for a single-storey home. Soft washing applies a biodegradable mould-killing solution at under 500 PSI, lets it dwell, then rinses gently. That kills mould, algae and lichen at the spore level so the growth does not return within weeks, which is what happens when high pressure strips only the visible surface layer. It is safe on painted weatherboard, render, fibre cement, Colorbond cladding, brick, and tile or Colorbond roofs. Coffs Harbour humidity averages 71% to 81% year-round at 18-27°C, so black streaking on render, eaves and fascia and green growth on shaded south-facing walls are near-universal from Woolgoolga to Nambucca Heads. Solutions are biodegradable and safe for gardens, pets and Coffs Coast waterways. Owner-operated by Matt Laing, fully insured, free on-site quotes. Call 0492 914 209.
Why Soft Washing Matters on the Coffs Coast
The Coffs Coast's subtropical climate — humidity averaging 70–80% and average temperatures 18–27°C — creates near-perfect conditions for mould, algae, and lichen growth on every exterior surface. Black streaking on render and eaves, green mould on south-facing weatherboard, and lichen patches on tile roofs are almost universal complaints in suburbs from Woolgoolga to Nambucca Heads. The problem with high-pressure cleaning these surfaces is that it only blasts off the visible growth — the spores remain in the porous substrate and regrow quickly. Soft washing applies a biodegradable cleaning solution that kills mould at the spore level, then rinses gently at controlled low pressure. Done correctly, soft washing is the only safe method for any painted, rendered, or coated exterior on the Coffs Coast — and the only treatment that actually holds up.

Buildings, Not Just Houses
Whole-building washes for commercial frontages, unit blocks and industrial cladding across the Coffs Coast.
Commercial Building Exteriors
Rendered and clad frontages, awnings, soffits and signage surrounds. Mould on a commercial frontage reads as neglect to a customer standing at the door, which is why this is usually booked on appearance rather than on maintenance schedule.
Strata Blocks & Unit Complexes
Whole-building washes for townhouse rows and unit blocks, including shared walls, stairwells and eaves. Doing a complex in one visit costs less per dwelling than owners arranging it individually, and it is the only way the finish matches across the building.
Industrial Cladding & Colorbond
Large Colorbond and fibre-cement elevations on warehouses and workshops. Low pressure is not a preference here — high pressure drives water behind sheeting and lifts the factory coating, and on a large elevation that damage is expensive to discover late.
Mould Remediation Across the Coast
Humidity between 71% and 81% year-round means mould on the Coffs Coast is a recurring condition, not a one-off event. Soft washing kills growth at the spore level so it regrows on a season's timescale rather than within weeks, which is what high-pressure blasting buys you.
Managed Property & Pre-Sale Programs
Agents and property managers running multiple listings, where a rendered wall gone green is the difference between a photograph that works and one that does not. Booked to a listing date, priced per property across a portfolio.

Frequently Asked Questions
Mould on a house exterior is removed by soft washing, not pressure cleaning. We apply a biodegradable mould-killing solution at low pressure (under 500 PSI), let it dwell so it kills the mould, algae and lichen at the spore level, then rinse gently. Because the spores are killed rather than just blasted off the surface, the growth doesn't return within weeks the way it does after a high-pressure-only clean. It's safe on painted weatherboard, render, fibre cement, Colorbond cladding, brick, and tile or Colorbond roofs — the delicate surfaces high pressure would damage.
Soft washing uses low-pressure water (under 500 PSI) combined with biodegradable cleaning solutions to safely clean delicate surfaces — painted weatherboard, render, Colorbond cladding, fibre cement, brick, and roof tiles. Pressure cleaning uses high pressure (2,000–4,000 PSI) that's only safe on hard surfaces like concrete and pavers. Soft washing kills mould and algae at the spore level so it doesn't grow straight back, which matters in the humid Coffs Coast climate.
No — that's the whole point. Pressure cleaning a painted weatherboard or rendered surface can blast paint flakes off, force water behind cladding, and erode soft render. Soft washing applies the cleaning solution at low pressure, lets it dwell, then rinses gently. Done correctly, it's the safest method for any delicate or coated surface, including tile and Colorbond roofs where high pressure can dislodge tiles or strip factory coatings.
Yes. We use only biodegradable cleaning solutions designed for soft washing — they break down naturally and won't harm gardens, lawns, pets, or run-off into Coffs Coast waterways. We also wet down surrounding garden beds before treatment as standard practice. This is one of the main reasons soft washing is the right method for residential properties: it gets a deep clean without the environmental hit of harsh industrial chemicals.
Yes — Laing Pressure Washing soft washes both residential and commercial buildings across the Coffs Coast.

Commercial soft washing is scheduled around tenants and trading hours, carried out to site safety requirements, and invoiced to the managing agent or body corporate directly. The biodegradable, low-pressure method is safe to use around occupied buildings and landscaping. Fully insured — call 0492 914 209 for a free quote.
