DOFF steam cleaning · London
DOFF steam cleaning. Stone facades cleaned from the ropes.
Superheated steam at low pressure lifts dirt and staining from stone and brick without the damage high-pressure washing can do. Delivered by rope access, with no scaffold on the facade.
What we do
Gentle on stone, tough on dirt
DOFF is a superheated steam cleaning system. It uses very hot water at low pressure, so it cleans stone, brick and detailed masonry without blasting the surface.
That makes it well suited to period and prestigious buildings. We combine it with rope access, so the facade is cleaned drop by drop from the roof without scaffolding the building, and we manage the street below so the public can pass safely. See our Hyde Park Corner case study.

FAQs
DOFF cleaning: common questions
What is DOFF cleaning?
DOFF is a steam cleaning system that uses superheated water at low pressure. It removes dirt, staining and biological growth from stone and brick without the damage that high-pressure washing can cause.
Is DOFF suitable for old or listed buildings?
It is widely used on historic stonework because it is gentle on the surface. On a listed building you should check with the conservation officer first, and we are happy to provide method details to support that.
Do you need scaffolding?
Usually not. We clean by rope access from the roof, which keeps the facade and the street clear.
Which areas do you cover?
London, Kent and the South East.
