DOFF System

Our DOFF cleaning system is a Historic England-approved method designed specifically for cleaning traditional buildings without causing damage. Using high-temperature steam at low pressure, the DOFF system effectively cleans the porous structure of historic masonry, removing dirt, biological growth, and pollutants while preserving the integrity of the material. 

This gentle yet powerful system is also ideal for removing non-breathable plastic paints, which can trap moisture and contribute to damp issues in traditional buildings. See our gallery to view past projects, and contact us to learn how we can help restore your property with this specialist technique.
