Trusted by Sydney Schools for Over a Decade
Keeping a school safe, clean and well-maintained is about more than appearances
— it’s about protecting students, staff and visitors, and looking after the long-term condition of your buildings and grounds. Outdoor Cleaning Specialists (OCS) has been delivering exterior cleaning and maintenance services to Sydney schools since 2007, and we understand the unique demands of working on active school sites.
From heritage buildings to modern multi-storey campuses, we help schools across Sydney stay safe, presentable and compliant — with minimal disruption to the school day.
WHY CHOOSE OCS
A documented management system, not just a crew with equipment
Many exterior cleaning contractors operate informally. OCS maintains a full documentation suite covering safety, environmental management, and standard contract terms — the same rigour expected of a head contractor, scaled to a specialist trade, and backed by Cm3 pre-qualification.
✅ Cm3 certified, meeting the pre-qualification standard used by government agencies, councils, and major property portfolios.
✅ A WHS Management Plan maintained against current NSW legislation, with SWMS for all high-risk work (rope access, EWP, electrical, falls from height).
✅An Environmental Management Plan aligned with AS/NZS ISO 14001:2016, covering stormwater, chemical management, and heritage/cultural site protocols.
✅ A Standard Clauses Library of pre-approved contract wording covering general terms, site access, service-specific risk disclosures, and site-type-specific obligations.
✅ Demonstrated capacity to deliver large-scale programs — 12,000 m² sites completed within a one-week schedule, and multi-point high-level facade programs across major hospitality sites — without compromising method or finish.
Our School Cleaning Services
OCS provides specialist exterior cleaning for schools across Sydney, including roof and gutter cleaning, building and facade washing, and hard surface cleaning. We work around school hours, pupil-free days and holidays, so your grounds stay safe and presentable without disrupting staff or students.
School Roof & Gutter Cleaning
Blocked gutters and dirty roofs are more than an eyesore. They’re a safety and maintenance risk. Overflowing gutters can damage classrooms, walkways and building facades. Debris build-up also raises fire risk in warmer months.
We clean roofs and gutters on school buildings of every type, including multi-storey blocks and hard-to-access rooflines. Our team uses fully equipped access gear, so we never rely on the building itself for support. Wherever possible, we schedule work around school hours, pupil-free days or holiday periods.
School Building & Facade Washing
First impressions matter — to prospective families, your community, and the people who spend their days on site. Our soft-wash and pressure-wash cleaning removes grime, mould, algae and pollution staining from exterior walls, cladding, awnings and signage. We restore your school’s presentation without damaging surfaces or finishes.
We’ve cleaned everything from heritage sandstone buildings to large modern facades, using the right pressure, technique and cleaning agents for each surface.
Hard Surface Cleaning for Schools
Walkways, quadrangles, courtyards, undercover areas and outdoor sports surfaces take a daily beating from foot traffic, weather and organic growth. Slippery, grimy surfaces are also a genuine safety concern for students. Our hard surface cleaning removes built-up grime, moss, mould and staining from pavers, concrete, asphalt and tiled areas — improving both the look and the safety of your grounds.
