DOFF cleaning, in Devon, Cornwall and surrounding counties, is a specialist steam-based method used to clean sensitive surfaces and historic buildings. It uses superheated water at temperatures up to 150°C combined with low pressure. This allows us to remove dirt, paint, algae and pollution without damaging the surface underneath.

Unlike high-pressure cleaning, DOFF cleaning gives full control over temperature and pressure. This makes it suitable for delicate materials such as timber, sandstone and soft masonry. The system removes moss, algae, lichen, fungi and graffiti effectively, often without the need for chemicals. As a result, it provides a safe and environmentally responsible cleaning solution.

DOFF cleaning is widely used for heritage and conservation projects. It delivers a deep clean while protecting the structure and long-term condition of the building. Because the system relies on heat rather than force, it works well on listed buildings, monuments and historic stonework.

This method is ideal for maintaining architectural features without causing damage. It also protects surrounding areas, making it safe for public spaces when carried out correctly. For this reason, conservation professionals often choose DOFF cleaning for sensitive restoration work.

At RM Builders & Contractors, trained operatives carry out all DOFF cleaning work. We follow strict safety procedures and adapt our approach to suit each surface. This ensures we achieve the best results while protecting the material.
