Drone Water Blasting

Instant Cleaning with Drone Water Blasting

For walls and surfaces that need more than a treatment, our latest service combines drone technology with a high-pressure water blaster.

 

The water blaster remains safely on the ground, while the drone lifts the hose and nozzle for direct, high-pressure cleaning from above.


This service can be used on its own or in combination with chemical treatments for long-lasting results.

Perfect for:

  • Heavy moss, mould, and grime removal
  • Fast turnarounds where immediate results are needed
  • Hard-to-reach areas that are unsafe for ladders or scaffolds
  • Sensitive areas that can not be walked on without damage
