Named crew, WWC-checked, no subcontractors, holiday and term-time scheduling available.
Exterior Areas We Clean
The exterior of a Melbourne school campus encompasses a wide range of surface types, each with different contamination profiles and cleaning requirements. A north-facing rendered wall develops different biological growth to a south-facing brick wall; a synthetic sports court needs different treatment to a concrete path; a colorbond fence requires a different method to a brick boundary wall. The site visit maps every exterior zone and identifies the right method for each before any work is quoted or scheduled.
Building facades & walls
Painted render, brick, block and cladding surfaces across all building faces. Biological growth on south and shaded walls, pollution deposits on traffic-facing faces, spider webs and bird contamination at eave and downpipe areas. Method matched to the cladding type — pressure for bare masonry, soft-wash for painted and render surfaces.
Playgrounds & outdoor equipment
Playground hard surfaces, soft-fall surrounds and outdoor equipment structures. Algae accumulation in shaded play areas, rubber crumb tracked across concrete, bird contamination on equipment tops and flat roof play structures. Low-pressure methods used on synthetic and soft-fall surfaces to preserve material integrity.
Sports courts & hard areas
Basketball and multi-use courts, netball courts, tennis courts and hard-surface running areas. Court surfaces accumulate algae growth in shaded zones and wet-weather debris tracked from adjacent grass areas. High-pressure rotary cleaning removes contamination from court line markings and playing surfaces without damage to surface coatings or line paint.
Covered walkways & canopies
Covered walkway undersides, roof panels, gutters and support columns all accumulate cobwebs, bird droppings and algae growth that are visible to students and visitors walking beneath them. Covered walkway cleaning addresses the underside of the roof structure, the support columns and the connecting wall surfaces in a single visit — surfaces that are often overlooked in individual area cleans.
Fencing, signage & gates
Perimeter fencing, school signage panels, entry gate surrounds and shade sail structures. These are among the first surfaces seen by families arriving at the school and form the initial impression of the facility's maintenance standard. Powder-coated and painted metal fencing is cleaned at reduced pressure; shade sail fabric is cleaned with low-pressure chemical wash.
Car parks & external paths
External path networks, car park surfaces, bin enclosure surrounds and hard-stand areas adjacent to buildings. These zones carry concentrated traffic and accumulate oil deposits, tyre marks and general grime at a higher rate than playground surfaces. For a full breakdown of path and car park cleaning, see the pressure cleaning page.
Building Facade & Wall Cleaning
School building facades develop different contamination types depending on their orientation, cladding material and proximity to trees, soil and vehicle traffic. No single cleaning method is safe and effective across all facade types — selecting the wrong one strips paint from render, erodes mortar joints from brick or damages cladding panels. The method is determined at the site visit by the surface type and contamination present.
High-pressure cleaning — bare masonry & concrete block
Exposed brick, concrete block and unpainted masonry surfaces tolerate direct high-pressure cleaning well. Algae, moss, pollution deposits and biological staining are removed mechanically by the pressure stream without chemical pre-treatment in most cases. Where deep-rooted lichen or heavy biological growth is present on older brickwork, a chemical pre-soak is applied to the surface before pressure is introduced to reduce the pressure required and protect the mortar joints from abrasion.
Soft-wash — painted render, colorbond & cladding
Painted render, colorbond steel, fibre cement cladding and timber weatherboard surfaces cannot be pressure cleaned without risk of paint stripping, surface etching or panel delamination. Soft-wash applies a low-pressure biocide and surfactant solution to the surface, where it dwells and kills the biological growth at the root. The dead growth is then rinsed away at low pressure — typically 300 to 600 PSI, well below the threshold that damages coatings. The result lasts longer than pressure cleaning on these surfaces because the biological contamination is killed rather than physically scraped off, which delays regrowth significantly.
Water-fed pole — upper storey glass & eave areas
Upper-storey windows, eave undersides and high wall areas adjacent to roof junctions are cleaned using purified water-fed pole systems from ground level where the building height and configuration allows. This eliminates the need for elevated access equipment on the majority of school building facades during the exterior clean, reducing both cost and safety risk. For full details on window cleaning methodology, see the window cleaning page.
Playground & Outdoor Equipment Cleaning
School playgrounds present a particular cleaning challenge because of the mix of surface types within a small area — concrete, asphalt, rubber soft-fall tiles, synthetic turf, timber, metal and plastic equipment structures often sit within metres of each other. Applying the same pressure and method across all of them is not appropriate: soft-fall rubber tiles require a gentle low-pressure rinse, while adjacent concrete can tolerate high-pressure hot-water treatment. The equipment structures — slides, climbing frames, balance beams, benches and shade structures — are cleaned separately from the ground surfaces at the same visit using surface-appropriate methods.
Playground cleaning is most impactful when scheduled at the start of the school year in late January — after the summer break during which biological growth re-establishes on shaded surfaces — and again at the start of term three after Melbourne's wet winter. These two visits, aligned with natural regrowth cycles, maintain playground surfaces more efficiently than reactive cleaning after visible deterioration has set in.
Combine with gutter cleaning: Exterior cleaning visits are commonly combined with gutter cleaning in a single holiday booking — both services require similar site access, reducing the total cost compared to two separate visits. See gutter cleaning for details.
Graffiti Removal
Graffiti on school property — whether spray paint on a brick boundary wall, marker on a colorbond fence panel or sticker accumulation on signage — requires prompt removal. Visible graffiti that remains on a school building for more than a few days invites further tagging and creates the impression of poor facility oversight. Golden Star offers reactive graffiti removal as a standalone service with a fast-response turnaround, and graffiti removal can also be included as a scope item in a scheduled exterior clean for campuses with recurring incidents.
Paint graffiti removal
The substrate type is identified before any solvent is applied — incompatible solvents strip the underlying surface coating along with the graffiti on painted render or colorbond surfaces. Substrate-matched chemical removers are applied with controlled dwell time to loosen the graffiti paint before low-pressure rinsing. Multiple passes are standard for dark or metallic spray paints on porous masonry. Anti-graffiti protective coatings can be applied after removal to make future incidents easier to clean.
- Substrate-matched solvent selection
- Safe for painted render and colorbond
- Anti-graffiti coating available post-removal
- Fast-response scheduling available
Sticker & marker removal
Sticker accumulation on signage panels, fencing and door surfaces and marker graffiti on glazed tiles, glass and powder-coated metal are addressed with solvent-based removers appropriate for each surface. Sticker adhesive residue left after the sticker face is removed requires a separate adhesive solvent treatment — simply peeling or pressure cleaning over residue embeds it further into the surface texture and makes final removal harder. All solvent products used are disposed of in accordance with EPA Victoria requirements.
- Adhesive residue treatment included
- Safe on glazed tiles and glass
- Powder-coated metal safe
- EPA-compliant solvent disposal

Frequently Asked Questions
Twice per year — aligned with the summer and winter school holiday breaks — is the recommended minimum for most Melbourne schools. Schools with high tree coverage, south-facing rendered walls or significant bird activity may need quarterly treatment of specific surfaces. Graffiti removal is handled reactively rather than on a fixed schedule. The right frequency for each zone is confirmed at the site visit based on current surface condition, building orientation and seasonal exposure patterns.
Soft-wash uses a low-pressure chemical solution — rather than high-pressure water — to treat biological growth on building surfaces that cannot tolerate direct pressure cleaning. It is the correct method for painted render, colorbond cladding, timber weatherboards and older brick where surface coatings or mortar joints would be damaged by pressure. The chemical solution kills the biological growth at the root before a low-pressure rinse removes the loosened contamination. The result lasts longer than pressure cleaning on these surfaces because regrowth is significantly slower when the root structure has been chemically treated.
Yes. Ground-level facade washing, path and playground cleaning run during term time from outside the building without entering classrooms or disrupting lessons. Elevated facade work — upper-storey surfaces or high eave areas — is scheduled outside school hours or during Victorian school holidays. Graffiti removal is available at short notice on weekends or after hours year-round. All scheduling is coordinated with the school business manager to ensure no disruption to the teaching program.
A full exterior clean — facades, covered walkways, playground and court surfaces — for a standard Melbourne primary school typically starts from $600 to $1,500 depending on campus size and the surfaces involved. Individual area cleans are available and priced per visit after a site assessment. For a full breakdown, see the pricing page or contact us for a written quote after the free site visit.
