Window cleaning, or window washing, is the cleaning of architectural glass used for structural, lighting, or decorative purposes. It can be done manually, using a variety of tools for cleaning and access. For windows that are more difficult to reach the use of specialist access equipment will be necessary. Examples include rope access, travelling ladders and gantries on the premises exterior or suspended access equipment (SAE) e.g cradles and Building Maintenance Units. Each method of window cleaning will be discussed below.
Rope access is a form of work positioning, initially developed from techniques used in climbing and caving, which applies practical ropework to allow workers to access difficult-to-reach locations without the use of scaffolding, cradles or an aerial work platform. Rope access technicians descend, ascend, and traverse ropes for access and work while suspended by their harness. Sometimes a work seat may be used. The support of the rope is intended to eliminate the likelihood of a fall altogether, but a back-up fall arrest system is used in case of the unlikely failure of the primary means of support. This redundancy system is usually achieved by using two ropes – a working line and a safety line.
The most common applications for modern rope access include inspection, surveying, maintenance, and construction on bridges, dams, wind turbines, towers, buildings, and industrial plants. While inspection is the most common application, painting, welding, cutting and heavy material handling can be accomplished by rope access professionals using specialised procedures.
The Industrial Rope Access Trade Association (IRATA International) has in place a continuously evolving regime with procedures that members are required to follow, which are monitored for compliance to ensure a safe system of work is established and maintained.

Advantages of Rope Access Window Cleaning
The advantage of using rope access methods lies mainly in the speed with which workers can get to or from difficult locations and then carry out their work, often with minimal impact on other operations. Another major benefit is that the combination of the total man-hours and the level of risk for a particular task (man-at-risk hours) is often reduced when compared with other means of access and their associated risks and costs.
The industry adheres to safety characteristics including:
- When working a rope access the technician always has at least 2 attachments, each having an independent anchorage point.
- When the worker is supported by ropes, each of the worker’s ropes will have a fail-safe descent mechanism.
- All secondary tools and equipment (e.g. drills, sealant) are attached by lanyards to the worker’s harness to avoid danger to people below.
- A minimum of two trained technicians are required for any job, each with the ability to rescue the other if needed.
- All technicians are independently assessed.
- All equipment is regularly inspected and maintained.
- No slippage.
- No permanent structures to be installed to support the rope access systems.
- Lesser manpower needed to install the rope access systems.
- Carefully refined codes of practice and working systems are used.
Trade associations such as IRATA and SPRAT have mandatory policies where member companies must submit all accident, incident and near miss occurrences to permit evaluation and comparison of information from an entire industry. This highlights any trends in incidents and assists in the evolution of equipment and procedures allowing continuing improvement to work practices. The above techniques along with the trade association’s organic approach has meant very few accidents since the beginning of this activity around the 1980s.
