Drone Commercial Building Cleaning
Planned exterior drone cleaning for commercial property, designed around the building's operating pattern.
Overview
Commercial property is judged by tenants and visitors on its exterior presentation. TERRABONA delivers planned drone cleaning executed without interrupting commercial operation.
Planning covers phasing, tenant coordination and documentation that integrates into the property's maintenance records.

Technical parameters
Water and pressure
- Required water volume calculated per project phase.
- Pressure selected according to material and working height.
- Stable supply through the ground-support system.
- Backup supply for continuous operation on large projects.
Cleaning agents
- Compatibility assessed for every material on the structure.
- Products used only where technically justified.
- Owner or designer approval obtained where required.
- Application and concentrations fully documented.
Limits and weather
- Increased wind sensitivity at greater working heights.
- Real-time weather monitoring during the mission.
- Airspace assessment in dense urban environments.
- Flight restrictions near infrastructure, helipads or airports.
Access and zones
- Exclusion zones on pavements, roads and entrances.
- Coordination with authorities for temporary traffic measures where needed.
- Take-off and landing points with controlled access.
- Communication protocol between pilot, observer and ground team.
Environment
- Overspray drift modelled for the working height.
- Protection of public space and vehicles.
- Runoff plan for urban drainage systems.
- Chemical use minimised in public environments.
Operational disruption
- Works carried out in low-activity windows.
- Sectional coverage so entrances remain open.
- Occupants, visitors and neighbouring properties informed.
- Defined stop-and-resume procedure for interruptions.
Quality control
- Zone-by-zone inspection from the air and from ground level.
- Points requiring an alternative access method recorded.
- Before-and-after documentation per section of the structure.
- Final report covering conditions, equipment and outcomes.
Maintenance
- Periodic cleaning programme based on exposure.
- Surface condition monitored between cycles.
- Framework agreements for recurring works.
- Integrated into the property's annual maintenance plan.
Information required for assessment
- Number of buildings and total area
- Operating hours and peak periods
- Parking areas and entrances
- Tenant requirements
- Existing maintenance programme
Frequently asked questions
Does the building need to close?
Usually not. Works are phased so entrances and core functions remain available.
Can a multi-property portfolio be covered?
Yes, through a multi-site programme with consistent methodology and centralised documentation.
