DOFF / steam cleaning
Specialised equipment is required to properly clean masonry and remove paint without damaging the masonry below. Sandblasting and other similar methods are well known to be damaging to the fabric of the building.

Gentle methods, approved in conservation
We exclusively employ gentle methods that have received widespread approval in the conservation industry.
We have our own in-house DOFF III and have access to other models and methods, so we can choose what's most suitable for your project.
Problems it solves
- Inappropriate paint trapping moisture in the walls
- Biological matter, soot and carbon staining
- Unsightly and illegal graffiti
Paint removal
Inappropriate paint can trap moisture in the walls, leading to visible damp problems internally.
Masonry cleaning
The DOFF and Thermatech effectively remove biological matter, soot and carbon staining.
Graffiti removal
Unsightly and illegal graffiti can be removed safely without damaging the masonry.
How the work proceeds
- Tell us about the masonry and what is on it
- Arrange a test panel with our DOFF system
- Clean or strip the full area with the pressure and heat carefully controlled
Materials
The process requires an understanding of the substrate (masonry) and of what paint has been used and how to effectively break it down, with or without the use of paint softeners. The careful control of pressure and heat allows the masonry to be cleaned without damaging it. Sandblasting, pressure washing and even hand cleaning can often damage historic masonry.
