TERRABONA
Service
Drone Façade Cleaning
Complex building envelopes cleaned by specialised drones, with compatibility assessment mandatory for every cladding material.
Overview
Modern façades combine materials with different durability, porosity and sensitivity to pressure and chemicals. TERRABONA applies drone cleaning only after a documented assessment of every material present on the elevation.
The service is intended for owners and asset managers who need a uniform result across large surfaces, with controlled disruption and complete documentation.

Technical parameters
Water and pressure
- Water quality selected per cladding material.
- Low pressure on sensitive panels and coated finishes.
- Adjustable flow for even coverage across large surfaces.
- Ground unit supply with continuous monitoring.
Cleaning agents
- Compatibility assessment mandatory for every façade material.
- Mild, biodegradable products where appropriate.
- Client-approved trial area before general application.
- Acidic or alkaline products excluded on incompatible materials.
Limits and weather
- Wind limits defined per height and building geometry.
- Local wind acceleration between buildings assessed.
- Operations suspended in adverse weather.
- Airspace and local flight regulations reviewed.
Access and zones
- Exclusion zones defined per elevation and per phase.
- Protection of entrances, terraces and parking areas.
- Ground equipment positions approved by the facility.
- Coordination with property security and technical services.
Environment
- Overspray control and protection of neighbouring properties.
- Runoff collection and disposal plan where required.
- Water use limited through targeted application.
- Products and quantities used are recorded.
Operational disruption
- Phased works so the property remains operational.
- Coordination with tenants and building users.
- Working hours set around noise and traffic constraints.
- Daily progress updates to the project owner.
Quality control
- Uniformity checked per panel and per zone.
- Aerial inspection carried out after cleaning.
- Areas with permanent staining or material degradation recorded.
- Completion pack with photographic evidence and methodology.
Maintenance
- Maintenance programme per material type and exposure.
- Soiling monitored to optimise frequency.
- Multi-year agreements for major properties.
- Aligned with the facility's planned maintenance calendar.
Information required for assessment
- Architectural drawings or material specifications
- Age and condition of the façade
- History of previous cleaning works
- Sensitive details and joints
- Neighbouring properties and public space
Frequently asked questions
Is every façade material suitable for drone cleaning?
No. Each material requires its own compatibility assessment before any work is carried out.
How is uneven appearance between materials handled?
Through different parameters per zone and client-approved trial areas.
Can permanent staining be removed?
Cleaning removes surface contamination. Permanent staining or material degradation is recorded and reported.
