A streak-free façade is not a successful outcome if the work exposed cleaners, occupants or the public to an avoidable fall, slip or struck-by risk. This commercial window cleaning safety guide is designed for Australian facility and property managers who need clear standards for planning, procuring and monitoring safe work at their sites.
Commercial window cleaning can range from ground-level internal glass to multistorey façades, skylights, atriums and difficult access points above busy entrances. The safest method is not always the fastest or lowest-cost option. It depends on the building design, access provisions, surrounding activity, weather and the condition of the glass and façade.
Start with the hierarchy of controls
Working at height requires more than personal protective equipment. Under Australia’s work health and safety framework, duty holders must eliminate risks where reasonably practicable or minimise them using the highest level of control available. For window cleaning, that means considering whether the work can be completed from the ground before relying on harnesses, ropes or ladders.
A water-fed pole system can often clean external glazing from ground level and remove the need for elevated access. It is particularly effective for low-rise offices, retail sites, schools and strata buildings where the glass can be reached safely without obstructing operations. However, pole work still needs controls for pedestrian separation, hose management, overhead services and water runoff.
Where ground-based cleaning is not practical, the provider should select an appropriate access method. This may involve an elevated work platform, a building maintenance unit, fixed access equipment, scaffold or rope access. Each method brings different site requirements, costs and limitations. A narrow laneway, soft ground, underground services or restricted loading capacity may rule out an elevated work platform. A façade without certified anchor points may rule out rope access.
Ladders are not a general substitute for planned height access. They may be suitable for short, low-risk tasks where safer options are not reasonably practicable, but they provide limited stability and do not allow a cleaner to maintain safe contact while carrying equipment. For regular commercial cleaning, a ladder-based approach should be the exception, not the operating model.
Conduct a site-specific risk assessment
A generic safety document does not account for the realities of your building. Before work starts, the cleaning contractor should inspect the site and prepare a task-specific risk assessment and safe work method statement where required. Facility managers should expect these documents to reflect actual access routes, hazards, controls and emergency arrangements.
The assessment should address the work area from arrival through to pack-down. That includes vehicle access, equipment unloading, roof entry, plant locations, public walkways, loading docks, internal furnishings and tenant activity. A cleaner may be safe at the window itself but still face significant risk while moving a pole, hoses or equipment through a busy lobby.
Particular attention is needed around:
- overhead powerlines and electrical services
- fragile roofs, awnings, skylights and unprotected edges
- vehicle movements in car parks, docks and service lanes
- pedestrians beneath elevated work areas
- glass damage, loose façade components and deteriorated seals
- wet floors, hose trip hazards and water entering internal areas
The assessment should also account for site-specific sensitivities. Healthcare facilities, childcare centres and schools need carefully controlled work zones, cleaning products appropriate to the environment, and scheduling that reduces disruption to patients, children, staff and visitors. Retail and hospitality sites may require early-morning, overnight or low-traffic service windows to protect customers and maintain presentation.
Verify access systems before cleaning begins
Building owners and managers have a critical role in ensuring permanent façade access systems are suitable, maintained and available for use. This includes roof anchor points, static lines, davits, monorails, building maintenance units and designated access paths.
Do not assume an existing anchor point is compliant simply because it is installed on the roof. The system needs appropriate certification, inspection and maintenance records, and the cleaning team must confirm it is suitable for the proposed task. Access equipment should only be used within its rated capacity and according to manufacturer and system requirements.
A professional contractor will inspect the available access arrangement before committing to a cleaning method. If the system is not certified, has unclear records or cannot safely reach the required area, the contractor should stop and recommend an alternative. This can be inconvenient, but continuing on an unverified system creates an unacceptable exposure for everyone involved.
For elevated work platforms, check that the planned machine can reach the work area while operating on suitable ground. Consider slope, surface condition, overhead clearance, underground services, exclusion zones and the need for traffic management. If the work is beside a public footpath or roadway, permits and approved controls may be necessary before equipment arrives.
Manage people, weather and daily site conditions
Commercial window cleaning affects more than the cleaning crew. Water, falling debris, equipment movement and temporary barriers can affect tenants, visitors, contractors and members of the public. Clear exclusion zones are essential whenever work occurs overhead or from an elevated platform.
Barriers and signage need to be positioned where people will see and follow them, rather than placed after the hazard. A concierge, security team or site representative can help redirect visitors during busy periods. At industrial facilities, coordinate with operations so cleaning does not conflict with forklifts, deliveries or mobile plant.
Weather conditions can change the risk profile quickly. High winds can make elevated platform and rope-access work unsafe, while rain can create slippery surfaces and reduce visibility. Heat, lightning, poor light and sudden storms also require a clear stop-work process. The work plan should allow for postponement without pressuring workers to proceed in unsuitable conditions.
Cleaning chemicals and pure-water systems should be selected and used with care. Products must be suitable for the glass, frame material and surrounding surfaces. Safety data sheets should be available, and chemical storage must prevent spills in plant rooms, lifts, corridors or public areas. On internal works, protect floors and furnishings from water spotting and slip hazards with controlled application and prompt clean-up.
Check competence, not just paperwork
Insurance certificates and induction records matter, but they are only part of contractor verification. The window cleaning team should have demonstrable competence in the actual access method proposed for your site. Rope-access work, elevated work platform operation and specialised façade systems require relevant training, experience and supervision.
Ask how the crew will communicate while working, who supervises the job, and what happens if the lead operator is unavailable. Confirm that equipment inspections are current and that workers have suitable personal protective equipment for the task. For high-risk work, records should show more than a generic checklist completed at the depot.
A capable provider will also be transparent about limitations. If a section of glass cannot be safely reached, the correct response is to identify a safer method, a building modification or a planned access solution. Promising full results without a feasible access plan is a warning sign.
Plan for rescue and incident response
A harness is not a rescue plan. Any work involving fall-arrest equipment or rope access must have a documented, practical rescue arrangement. The team needs the equipment, trained personnel and response process to recover a worker promptly if a fall or suspension occurs.
Emergency planning should cover first aid, communications, site access for emergency services and notification procedures. On large sites, security and building management should know where elevated work is occurring and how to contact the supervisor. If the job changes during the day, such as moving to another elevation or roof zone, the work area and emergency information should change with it.
Near misses deserve attention even when no injury occurs. A dropped tool, failed barricade, unexpected wind gust or water leak may reveal a weakness in the system. Recording the event and correcting the control helps prevent a more serious incident on the next service visit.
Make safety part of the service standard
Window cleaning should be planned as part of the broader facility maintenance program, not treated as an isolated cosmetic task. Regular service schedules allow teams to understand the building, identify access concerns early and coordinate cleaning with maintenance, security and tenant requirements.
Perfect One Services applies a practical, site-led approach to commercial cleaning across complex facilities. The right cleaning method, competent people and clear controls protect workers while keeping your property clean, compliant and ready to represent your organisation well.
The best time to solve an access or safety issue is before the crew arrives at the glass. A well-planned service protects people first, then delivers the clear, professional presentation your property deserves.
