How to Prepare a Building for Rope Access Window Cleaning: A Checklist for Property Managers

The crew arrives at the agreed time. They go up to the roof and discover that the padlock key for the plant room is with the administrator, who is not working today. The security guard knows nothing about the work, so he asks for documents that no one has left with him. A tenant on the third floor has moved furniture close to the window because no one warned them in advance. A job that was supposed to take one day ends with the date being rescheduled and additional costs for both parties.

This article is a checklist for a property manager, administrator, or facility manager who wants to avoid similar situations. Preparing the building does not require a large amount of work, but it does require specific steps to be completed before the crew arrives.

Why Does Building Preparation Affect the Price and Completion Date?

The working time of a rope access crew is one of the main components of the assignment cost. Every hour spent waiting, looking for entrances, or solving logistical problems is time that could have been spent working. For one-day assignments, where the crew costs the same regardless of how many windows they clean, delays directly affect the scope of work completed or create the need for a return visit.

Good preparation shortens the completion time, reduces the risk of complaints, and limits inconvenience for residents or tenants. It is not a formality. It is part of efficient project delivery.

Checklist Before the Site Visit: Photographs, Drawings, Roof Access, and Technical Contact

Before the site visit or quotation confirmation takes place, it is worth collecting basic information about the building. This makes the conversation with the contractor specific and allows any technical questions to be resolved in advance.

What should you prepare before sending an enquiry?

•photographs of the façade from ground level, preferably showing all sides of the building;

•photographs of the roof, including a general view, edge condition, and visible safety anchor points or their absence;

•a floor plan or site plan, if available;

•information about the number of storeys and the type of glazing, such as opening windows, fixed windows, or a structural façade;

•the current condition of contamination, including whether it is standard dust or visible deposits or marks left after construction work;

•contact details for a technical person who can answer questions about roof installations.

This is the minimum that allows the contractor to initially assess the scope and select the method. If a site visit is required for complex buildings, it takes place at the quotation stage, before the contract is signed.

Safety Anchor Points and Roof Access: What Should the Property Manager Check?

The roof is the starting point for a crew working by rope access. Its condition and equipment directly affect whether the assignment can be carried out and how much it will cost.

Before the crew arrives, check:

•whether certified safety anchor points are installed on the roof, such as hooks, rope rails, or anchoring systems;

•when they were last inspected and whether they have valid inspection records;

•whether roof access is available, including keys, codes, and access cards;

•who has the keys to the plant room, technical shafts, and rooftop rooms;

•whether there are obstacles on the roof that may make movement difficult, such as installations, HVAC units, or masts.

If the building does not have certified safety anchor points, inform the contractor in advance. An alternative access method will need to be selected, or temporary anchoring systems will need to be installed. This affects both the quotation and the completion time. We have written more about technical safety requirements for work at height in our article on IRATA certification in work at height.

Communication With Tenants, Residents, and Building Security

External window cleaning is usually less disruptive than other building works, but it requires informing people who may be surprised by it. Lack of communication is one of the most common sources of complications.

What should be communicated, and when?

Security or reception: inform them at least two days in advance. Provide the contractor’s name, date, scope of work, and list of people entering the facility. Make sure that security will not block access to the roof or the building premises.

Tenants or residents: provide written information by email, lift notice, or noticeboard at least three to five days before the work. The message should include the date, working hours, and information that workers may appear outside the windows. For opening windows, ask people to move curtains, blinds, and objects away from the window area.

IT or data protection departments: in office buildings, some companies may have restrictions related to screen visibility or access to rooms. It is worth agreeing this in advance.

Car park manager: if the work will be carried out above an above-ground car park or parking spaces, several spaces may need to be temporarily taken out of use.

Securing the Area Below the Building: Pavements, Car Parks, Greenery, and Entrances

The area below the rope access technicians must be secured. Responsibility for fencing off the area and informing pedestrians lies with the contractor, but the property manager can significantly facilitate this process.

What needs to be agreed?

•whether the pavement next to the building is managed by the road authority or the city; if so, permission for temporary fencing may be required;

•which building entrances may be temporarily closed or restricted while the crew is working;

•whether there is greenery or a surface below the building that is susceptible to damage from equipment, such as hedges, lawns, or paving stones;

•whether there are cables, pipes, or above-ground installations nearby that may interfere with the work.

A standard protection zone is an area marked with tape or barriers, corresponding to the working height plus a safety margin. The contractor determines its width after assessing the building conditions. Your role as the property manager is to enable the zone to be set up and to inform users of the area.

Access to Water, Electricity, and Technical Rooms

Depending on the cleaning method, the crew may need access to utilities. Agreeing this in advance helps avoid downtime on the day of the work.

Water:

•when cleaning with demineralized water, the crew usually brings its own water or demineralization unit, but may need access to a valve or hydrant as a supplementary source;

•for standard cleaning, access to a garden hose or technical water valve on the roof or near the building may be needed;

•agree who can provide access and where the hydrant key is located.

Electricity:

•for larger assignments involving a unit or pressure equipment, a 230V or 400V socket near the work area may be required;

•if the crew needs electricity, this should be indicated at the quotation or order confirmation stage.

Technical rooms:

•plant rooms, ventilation shafts, and rooms with rooftop installations should be accessible; make sure that keys are available to the person appointed to coordinate the assignment.

What Does the Day of Rope Access Window Cleaning Look Like?

Knowing what a typical working day looks like makes coordination with tenants and security easier.

Morning, or start of work: the crew arrives at the building, checks the safety anchor points on the roof, and installs working and safety ropes. They mark out the protection zone at ground level. The crew coordinator contacts the person appointed by the property manager.

During the work: rope access technicians work in sections, moving down the façade from top to bottom. For multi-wing buildings, they work section by section. Working time depends on the surface area and the condition of the dirt. The crew provides progress updates and reports any difficulties, such as lack of access to a specific section.

After completion: ropes and equipment are dismantled, barriers are removed, and quality acceptance is carried out with the person appointed by the property manager. The contractor should provide information about any window or seal defects noticed during the work.

The Most Common Mistakes in Building Preparation

Based on completed assignments, the following are the mistakes that most often complicate project delivery:

•no information provided to security, resulting in the crew being treated as unknown persons and the need to call the property manager to confirm the assignment;

•blocked roof access, with the key held by a person who is unavailable or unaware of the assignment;

•no information provided to tenants, leading to complaints about the unexpected appearance of people outside windows and the need to interrupt work;

•an unsecured car park below the building, with cars parked under the work zone and the need for intervention by security or the police;

•outdated information about safety anchor points, where hooks are present on the roof but have no valid inspections, meaning the crew cannot use them;

•no appointed contact person on the day of work, with operational decisions made by phone by someone who is on leave or in a meeting.

Each of these mistakes can delay or interrupt the work. Avoiding them does not require a large amount of effort, only proper planning.

Ready-to-Copy Checklist Before Sending an Enquiry

The list below can be used as a control point before contacting the contractor and before the day of work.

Before Sending a Quotation Enquiry

•photographs of the façade from all sides;

•photographs of the roof and visible safety anchor points;

•information about the number of storeys and window types, such as opening windows, fixed windows, or façade glazing;

•description of the dirt condition, such as standard dirt, deposits, or post-construction contamination;

•contact details for a technical person familiar with rooftop installations;

•preferred date or time window for completion.

Before the Day of Work

•security informed, including contractor name, date, and list of people;

•roof and plant room keys available to the appointed person;

•tenants or residents informed in writing;

•area below the building prepared for possible fencing;

•access to water or electricity agreed, if needed;

•contact person available throughout the working day;

•users informed that parking spaces below the building may need to be vacated.

That is all. Preparing the building is not complicated, but it requires someone to take responsibility for it and do it in advance, not on the morning of the work.
