DOFF Cleaning

At Crown Services we specialise in providing professional DOFF cleaning services for buildings of all sizes and conditions. Our approach combines the precision of our specialist access skills with one of the most advanced cleaning systems available today, including the industry-leading DOFF cleaning system. The result is a safe, effective and environmentally friendly way to restore the appearance of your property while preserving its structural integrity.

We understand that some buildings present complex cleaning challenges due to height, surface type or delicate features. That’s why we combine the DOFF system with our rope access expertise, enabling us to carry out work even at significant heights without the need for excessive scaffolding or disruptive access platforms. As long as the site has a water supply, we are ready to go with our specialist DOFF steam cleaner equipment.

What is DOFF Cleaning?

The DOFF system is a steam-based cleaning process that uses super heated water vapour to remove dirt, grime and biological matter from a wide range of surfaces. Using a specialist DOFF cleaner, water is heated to a high temperature of up to 150°C and delivered through specialist nozzles. This allows us to achieve powerful DOFF steam cleaning results while keeping the temperature and pressure precisely controlled to suit the needs of the surface.

Unlike traditional pressure washing, the DOFF cleaning process uses minimal water and steam combined with gentle pressure, so there is no risk of thermal shock or deep saturation. This makes it the preferred choice for cleaning heritage, listed and historic buildings, particularly for DOFF cleaning for historic stonework, where the fabric of the structure must be protected at all times.

The Benefits of the DOFF Cleaning Process

DOFF cleaning delivers outstanding results while protecting the building’s materials. The heated water vapour effectively removes moss, algae, fungi and other biological matter that can cause long-term damage if left untreated. It is also powerful enough to strip away graffiti, paint, oil, grease and other stubborn contaminants, making it highly effective for DOFF cleaning paint removal and DOFF system paint removal.

At Crown Services we are committed to environmentally responsible practices. The DOFF cleaning system achieves its results without the use of harsh chemicals, relying instead on the cleaning power of water and steam. This means there is no risk of introducing harmful substances into the environment and no chemical residues left behind on your property.

The high temperature of the water vapour ensures that surfaces dry quickly, reducing disruption and the potential for trapped moisture. This is particularly important for porous materials like stone, brick and wood, where excessive water can lead to deterioration over time.

Suitable Surfaces and Applications

One of the reasons we use the DOFF system is its versatility. It can be applied to an extensive range of surfaces without causing damage, making it ideal for:

Historic and Listed Buildings – gentle enough to preserve delicate masonry while still removing years of dirt and grime, including specialist DOFF masonry cleaning.
Commercial and Public Buildings – restoring the appearance of brick, stone, concrete and cladding.
Graffiti and Paint Removal – eliminating unwanted markings and DOFF paint without damaging the underlying surface.
Biological Growth Removal – tackling moss, algae and fungi to protect structural integrity.
Industrial Applications – removing oil, grease and pollutants from warehouses, transport depots and other facilities.
Roof Cleaning – safe and effective DOFF roof cleaning for sensitive surfaces without causing damage.

How the DOFF Cleaning Process Works

The cleaning process begins with a detailed assessment of the building to determine the right temperature and pressure settings. The DOFF unit then heats water to a high temperature in a self-contained hot box before delivering it to the nozzle in the form of superheated water vapour.

This DOFF steam cleaning method gently lifts away contaminants without damaging the surface. Because the water and steam volume is low, surfaces dry within minutes, preventing long-term moisture issues. The process is highly effective at removing both surface dirt and deeper-seated biological matter, ensuring a thorough and lasting clean.

Protecting Your Building for the Future

Regular maintenance using the DOFF cleaning system not only restores the appearance of your property but also helps to preserve it for years to come. By removing harmful biological matter and pollutants, we prevent deterioration and extend the lifespan of building materials. This is especially important for heritage and listed buildings, where preservation is a legal and cultural responsibility.
