What facade cleaning with rope access means
In short: the method uses two independent ropes and a certified technician who descends along the facade and cleans the surface manually or with professional equipment, without installing scaffolding.
Definition of rope access
Rope access is work at height using two independent ropes – a working rope and a safety rope. This principle stands behind every EdgeRope service, from facade cleaning to high-level installations and inspections. You can learn more about our approach on the page for rope access and work at height.
When the method performs better than scaffolding or a cherry picker
Scaffolding adds days for installation and rental costs, while a cherry picker cannot always reach inner courtyards, narrow streets and complex building shapes. Our rope access technicians can position themselves quickly, without closing pavements or stopping movement around the building. For one-off or scheduled facade cleaning, this is often faster and more cost-efficient.
Why summer is a suitable season for facade cleaning
In short: warm and dry months provide faster drying, more stable rope conditions and the opportunity to plan annual building maintenance before the autumn rains.
Weather conditions and result quality
Warm and dry weather speeds up drying and reduces water marks on glass. Stable rope conditions allow the team to cover a larger area per day, which can lower the cost per square metre for the client.
Planning annual maintenance
Dust, bird droppings and traffic soot build up throughout the year. A summer wash restores the appearance of the building, while preventive cleaning before winter helps keep the glazing in good condition. That is why we recommend planning the schedule for the warm months before available dates fill up.
Facade types and the right cleaning methods
In short: each type of cladding requires a different pressure level, detergent and technique, which is why the inspection before work defines the method and protects the surface from damage.
Glass and curtain wall facades
A curtain wall is an external envelope made of glass and aluminium, which does not carry the building’s structural load. It is cleaned with a mild detergent and a squeegee, while large areas can be washed with deionized water, which dries without visible marks.
Stone and tiled facades
Natural stone and ceramic tiles absorb moisture, so we work with controlled pressure and neutral detergents. The goal is to remove deposits without opening the joints or pushing dirt deeper into the material.
Etalbond and metal panels
Etalbond is an aluminium composite panel widely used on commercial buildings. The surface is sensitive to scratching, so cleaning is done with soft cloths, low pressure and detergents with balanced pH.
Cleaning technologies and detergents
In short: the choice between deionized water, pressure washing and manual cleaning depends on the type of dirt, the facade material and access to the surface.
Deionized water
Deionized water is purified from salts and minerals, which means it does not leave limescale marks after drying. It is preferred for glass surfaces because it delivers a clean result without heavy chemical use or additional wiping.
Pressure washing
For concrete, render and durable cladding, we use pressure washing equipment with adjustable pressure. The operator controls the force of the jet according to the material, removing soot, moss and mildew without damaging the surface.
Manual cleaning and special detergents
For local stains, graffiti or sticky deposits, the work is done manually with targeted cleaning products. This approach gives precision in areas where automated methods could spread contamination to adjacent sections.
Safety and IRATA standards
In short: professional cleaning at height follows the international IRATA code, which requires a trained team, double protection and a rescue plan prepared in advance.
International code of good practice
IRATA is the international association for industrial rope access. Its International Code of Practice, known as ICOP, defines technical and safety requirements and is a recognised benchmark for professional rope access work worldwide. The EdgeRope team includes technicians with IRATA certification and practical experience in rope access operations.
Certification levels
A level 1 technician performs routine tasks under supervision, level 2 can lead smaller teams, while level 3 designs safety systems and is responsible for the whole site. Supervision and team organisation are planned according to the complexity and risk of each specific project. You can learn more about the certified EdgeRope team and its field experience.
Risk assessment and rescue plan
Before each job, the team prepares a risk assessment and method statement. Equipment, ropes and harnesses are checked before, during and after the work, while a rescue scenario is prepared for the site in case of an incident. This documentation gives the building owner proof of a controlled and compliant process.
How a project works step by step
In short: each project goes through an inspection, a specific offer, work zone protection, execution and final quality control.
Inspection and offer
The inspection defines the building height, facade type, anchor points and level of dirt. Based on this, the client receives a specific offer, not an approximate price. You can request an on-site inspection at a convenient time.
Preparation and safety of the area
Before the descent begins, the team sets up anchor points, secures the area below and marks the working zone. This preparation protects both the technicians and the people around the building.
Execution and quality control
The technicians clean the facade section by section and check the result after each descent. Final inspection ensures an even finish without missed zones. You can see the type of projects and services we handle on the EdgeRope services page.
Prices and price-forming factors
In short: with rope access, the price is often calculated per square metre, but the exact value depends on height, access, dirt level and facade type, which is why EdgeRope provides a specific offer after inspection.
How the price is formed
For similar services on the market, the price is often calculated per square metre, but in rope access work, single numbers can be misleading. Height, descent length and the level of dirt can change the calculation significantly, so the reliable price comes after inspection, not over the phone.
Volume and discounts
A larger area and a regular maintenance contract can reduce the cost per square metre, because the team covers more during one site visit. A one-off cleaning of a small building will usually have a higher unit price than scheduled maintenance.
Scheduled maintenance
For office and commercial buildings, we offer scheduled facade cleaning contracts that define the timetable and price for the year ahead and are usually more cost-efficient than single call-outs. You can see how we work in practice through our client reviews.
Related work-at-height services
In short: a rope access team can combine facade cleaning with installations, inspections and removal of unstable elements, so the building receives complete maintenance from one contractor.
High-level installations and glazing
The same team installs and replaces windows, glass and cladding, paints steel and concrete structures, and services 5G cellular networks at height. When cleaning reveals damaged glass, a joint or a facade element, we can offer follow-up replacement or repair through the same team, without the need to look for a separate contractor.
Removal of unstable elements and structural inspections
Removal of unstable elements means the controlled removal of dangerous rock or facade parts that could endanger people below. During an inspection, we also check connections, joints and structural details, as well as personal protective equipment, so that problems can be identified before they become emergencies.
Why choose a certified team
With EdgeRope, you get clearer documentation, traceability of the work and a team that plans each step according to the risk of the site. Facade services, installations and inspections come from one contractor, which reduces coordination costs and gives you a clearer action plan.
Frequently asked questions
How often should an office building facade be cleaned?
Glass facades in urban environments are usually cleaned twice a year – once at the beginning of summer and once before winter. In heavily polluted locations with intense traffic, the frequency may increase to four times a year.
Is facade cleaning by rope access safe for pedestrians?
Yes, when the correct protocol is followed, the area below is secured and clearly marked. The team works with a two-rope system and a rescue plan prepared in advance, which makes the method controlled and structured.
Can work be carried out in rain or strong wind?
No, poor weather conditions stop the work for safety reasons. That is why dry summer months are preferred for planning larger projects.
What does the specific offer include?
The offer covers labour, equipment, detergents and securing of the working zone. After inspection, the client receives a specific offer according to the scope of work.
