Specialist Stonework Cleaning Services
Preserving the beauty and integrity of historic statues and landmarks is a delicate process that requires the right expertise and tools. At The Balmore Group, we specialise in DOFF steam cleaning, an advanced, non-abrasive method designed to remove moss, algae, and carbon staining without damaging the surface of the stonework.
What is DOFF Steam Cleaning?
The DOFF system is a superheated water-based cleaning method that effectively removes organic matter and atmospheric pollutants while maintaining the delicate structure of historic and listed buildings. Unlike high-pressure cleaning methods that can erode stonework, the DOFF system uses low-pressure, high-temperature steam to clean surfaces without causing harm.
Benefits of DOFF Steam Cleaning for Historic Stonework
- Gentle Yet Effective – Removes biological growth, dirt, and pollutants without abrasive chemicals or high-pressure damage.
- Eco-Friendly – Uses only water, avoiding harsh chemicals that could harm the environment or the stone.
- Preserves Historic Integrity – Safe for use on sandstone, limestone, marble, and other delicate stone materials.
- Prevents Regrowth – The high temperatures kill spores, reducing the likelihood of future moss and algae growth.
- Removes Carbon Staining – Eliminates stubborn black stains caused by pollution and weathering, restoring the original appearance of the stone.
