Millgrove Construction is a registered and approved DOFF cleaning contractor. We provide a stone, brick and roof cleaning service to both commercial and domestic customers throughout the UK.
DOFF cleans stonework, masonry and other surfaces using high temperature steam. Whilst the temperature in the system is high, the pressure on the surface being cleaned is very gentle and the volume of water is low. The surface is therefore not saturated and will be dry within minutes.
The system removes moss, algae, fungi and other biological matter and will also kill off spores. This means there’s then no need to use a chemical biocide during the removal process or as a protection against further biological activity.
