Cleaning inaccessible areas of buildings: a solution that finally reaches everywhere
Why part of the facade always gets "forgotten" in traditional cleaning, and how to fix it
Cleaning hard-to-reach areas is one of the most common challenges in building maintenance, and ironically these are the very areas where the most dirt builds up, because they are almost never cleaned properly. Upper corners, recesses between building wings, areas above sloping roofs or under projecting beams all tend to stay "out of the picture", even after a full facade clean.
Why do buildings have hard-to-reach areas at all?
Modern buildings often have complex geometry: internal corners, projecting balconies, ventilation recesses, spaces between two adjoining wings and roofs at different heights. Traditional cleaning methods, whether scaffolding, rope access or water-fed poles from the ground, simply aren't designed to reach all these angles safely or efficiently. The result is that the crew cleans what it can reach and skips the rest.
What's the problem with neglecting hard-to-reach areas?
Long-term neglect of inaccessible corners isn't just a cosmetic problem:
- Faster dirt build-up — shaded, inaccessible areas tend to develop mould and biological growth faster, precisely because they never get cleaned regularly
- Hidden structural damage — cracks or leaks in hidden areas are often only discovered once the damage is significant, similar to the recommendations of the Ministry of Construction and Housing on periodic inspections of the building envelope
- An uneven overall look — even if most of the facade is clean, one neglected corner stands out and spoils the overall impression
How does drone cleaning solve the problem of hard-to-reach areas?
True three-dimensional access — a drone isn't limited to a single working angle like scaffolding or rope access. It can manoeuvre around corners, under projections and between adjoining building wings, exactly the places that always stay "out of the picture".
Precise detection with real-time imaging — 4K + AI imaging technology pinpoints exactly where dirt is building up, even in areas that are hard to see with the naked eye from the ground.
Targeted spraying and rinsing — instead of skipping a problem area, the spray system treats it directly, including a final rinse with purified water that prevents water spots even at the most awkward angles.
No risk to the crew — inaccessible areas are often also the most dangerous to climb to. Cleaning from the air removes that risk completely.
Which areas usually count as "hard to reach"?
Internal corners between building wings, ventilation recesses and niches, areas under beams and architectural projections, sloping and intermediate roofs, and narrow gaps between neighbouring buildings.
Who should pay particular attention to this?
Buildings with complex or non-standard architecture, historic or older buildings with extensions added over the years, and adjoining buildings where the gap between them is almost impossible to reach with ordinary cleaning equipment. You can read more about our full working method and how it handles complex buildings.
Summary
Cleaning hard-to-reach areas is exactly where traditional cleaning methods consistently fall short, not through a lack of professionalism but because of a real physical limitation of the equipment. Drone cleaning tackles the problem at its root, so there are no more "forgotten corners" on your building's facade.
