In short
We remove algae, moss, mould, soot and flash rust without damaging the façade, using surface-protecting methods for listed and delicate buildings.
Algae, moss, mould, soot, bird droppings and flash rust not only spoil the appearance of a façade; over time they damage the material. Brocken selects the most suitable method according to the façade material (brick, natural stone, render, concrete, metal) and the type of contamination.
Methods
- Hot water and low pressure: rendered and painted surfaces
- JOS low-pressure rotation and Sponge-Jet: historic buildings, natural stone
- Wet abrasive blasting: clinker and concrete façades
- Ultra-high-pressure water jetting: heavily soiled concrete and steel
Complementary services
- Anti-algae and anti-mould treatment
