Why Choose Us

Professional Softwashing in Melbourne

Softwashing is the correct cleaning method for Melbourne's painted weatherboard homes, rendered walls, Hebel cladding, and textured exterior surfaces — where high-pressure blasting suited to concrete would strip paint, fracture render, and drive water behind the building envelope. The softwash process applies a controlled biocide solution at low pressure, allowing it to dwell and kill mould, lichen, and algae at the biological root rather than simply blasting off visible growth that regrows within months.

Most exterior staining on Melbourne properties is biological in origin — green algae driven by shade and moisture, black algae on north-facing render in humid conditions, and pink or orange lichen on rendered garden walls. These growth types have root systems that penetrate the surface layer. High-pressure washing removes the visible portion but leaves the root to regrow rapidly. The Squeegee Squad's softwash chemistry targets the root system, delivering results that typically last twelve to twenty-four months before retreatment.

Our chemistry selection accounts for your substrate. Render, painted timber, fibre cement, and brick each have different porosity and pH sensitivity. We use biodegradable surfactant-based solutions at concentrations appropriate to the growth type and surface — always below the threshold that would affect established landscaping, provided pre-wet and rinse protocols are followed. Garden beds, pot plants, and lawn areas adjacent to treated walls are pre-wet before application and rinsed thoroughly afterwards.

Softwashing is particularly popular across Melbourne's coastal suburbs — Bayside, the Mornington Peninsula, and the outer south-east — where salt-laden onshore winds deposit a mineral film on exterior surfaces that accelerates biological growth. Eastern suburbs properties under heavy tree canopy, particularly in the Nillumbik Green Wedge, also see rapid mould return without a biocide component in the cleaning treatment.

What You Get

What's Included

Every softwashing booking includes professional equipment, insured crews, and a satisfaction guarantee.

Substrate Assessment

Render, timber, brick, and cladding each receive a tailored treatment plan matched to growth type and surface sensitivity.

Low-Pressure Application

Biocide applied evenly at safe working pressure — no aggressive blasting on fragile or painted surfaces.

Garden & Surface Protection

Plants pre-wet and rinsed. Windows sealed where needed. Runoff directed away from sensitive landscaping throughout the visit.

How It Works

Our Process

  1. Exterior Survey

    We identify substrate, growth type, drainage, and access before quoting treatment strength and coverage.

  2. Prep & Protect

    Windows sealed or covered where needed. Adjacent gardens pre-wet and paths protected before any solution is applied.

  3. Treat & Dwell

    Solution applied evenly and allowed to work. Growth dies off over the following days for a deep biological clean.

  4. Gentle Rinse & Inspect

    Low-pressure rinse removes dead material. Final walk-around confirms even coverage and clean sightlines on all elevations.

Who We Serve

Residential & Commercial Softwashing

Residential

For residential properties, softwashing is most often applied to all exterior elevations in a single visit, working systematically from eaves to ground level. Weatherboard homes see the most dramatic visual improvement — green staining lifts from painted boards and window surrounds to reveal the original colour beneath. Rendered homes and Hebel panel cladding benefit from the gentleness of softwashing, since these materials can be permanently damaged by high-pressure water infiltration behind panel joints and around window flashings.

Commercial

Commercial softwashing covers apartment building facades, retail strip cladding, school building exteriors, and aged-care facility rendered walls — surfaces that need to remain clean for regulatory compliance and professional presentation but cannot sustain the vibration and surface stress of pressure washing. We provide before-and-after documentation for body corporate records and can schedule repeat treatment programs aligned to strata maintenance plans. Large facade cleans may require a boom lift — these are quoted separately after a site inspection.

Frequently Asked Questions

What is the difference between softwashing and pressure washing?
Pressure washing uses force to blast dirt away — ideal for hard surfaces like concrete and brick. Softwashing uses low pressure and biocide chemistry to kill organic growth at the root — the essential method for painted, rendered, and timber exteriors that high PSI would damage or delaminate.
Is softwashing safe for painted weatherboard homes?
Yes. It is the recommended method for older weatherboard homes in Melbourne's eastern suburbs where high pressure would strip paint, raise grain, and force moisture into gaps. We test a small inconspicuous area first if paint is already chalking or failing before proceeding to the full elevations.
How long do softwash results last?
Most treated surfaces stay clean for twelve to twenty-four months depending on shade, tree canopy, and proximity to the coast. Heavily shaded south-facing walls in dense tree cover may need annual treatment. Coastal properties in Bayside and the peninsula typically need retreatment every twelve to eighteen months.
Can softwashing be combined with roof or gutter cleaning?
Absolutely. Many Melbourne property owners book roof treatment, gutter clearing, and exterior softwashing together for a complete exterior refresh. We package these services for efficiency and typically apply a combined booking discount — ask when you enquire.
Will the softwash chemicals affect my garden or plants?
We pre-wet all adjacent garden beds and lawn areas before applying treatment and rinse them thoroughly afterwards. Our formulations are biodegradable and diluted to concentrations that comply with environmental safety guidelines. Established plants with healthy root systems are not adversely affected by the brief exposure from treatment runoff at working concentrations.
