When it comes to cleaning delicate stonework and historic façades, traditional high-pressure methods can do more harm than good. At Shire Stone Care, we use DOFF cleaning, a specialist low-pressure steam cleaning system that safely removes dirt, pollutants, and biological growth while protecting the integrity of the stone and surrounding materials.
Whether you’re looking to refresh heritage stone, restore a period building, or maintain an industrial façade, our DOFF cleaning services deliver exceptional results with minimal impact.
DOFF cleaning is a gentle, steam-based cleaning method specifically designed for porous surfaces like limestone, sandstone, terracotta, and other heritage stone materials. Unlike abrasive pressure-washing, DOFF uses controlled, low-pressure steam, often below the boiling point, which removes grime, soot, algae, and biological contaminants without damaging the surface or structure of the stone.
This method is widely accepted across conservation and restoration circles — particularly for historic buildings, listed properties, churches, and architecturally sensitive structures — because it preserves original textures and avoids surface erosion.
Heritage and stone façades face a unique combination of challenges, including:
Traditional high-pressure cleaning can force water into the stone’s pores, leading to long-term moisture damage and accelerated deterioration. DOFF cleaning avoids these issues by using steam at a low, safe pressure that lifts away contaminants without forcing water deep into the masonry.
At Shire Stone Care, our DOFF cleaning process follows a carefully designed workflow to ensure both effectiveness and protection:
Before any work begins, our team conducts a full site survey to understand the stone type, level of soiling, and any structural sensitivities. This allows us to tailor the DOFF process for maximum benefit.
We assess the condition of joints, mortar, and surrounding materials to ensure they are not adversely affected during cleaning. If needed, sensitive areas are protected before work commences.
Using the DOFF system, we apply low-pressure steam to the façade. The steam gently dissolves and lifts away soot, grime, biological deposits, and pollutants from the surface without abrasion.
After the steam cleaning phase, we conduct a controlled rinse — if required — and perform a final inspection to verify cleanliness and surface integrity. All wastewater and residue are managed responsibly.
