DOFF Steam Cleaning

Cleaning, Conservation and Restoration

Specialist Cleaning for Delicate and Historic Surfaces

DOFF steam cleaning is a highly effective, non-abrasive cleaning method used to remove dirt, algae, moss and other biological matter from various surfaces without causing any damage to the substrate. The DOFF machine produces and delivers steam of up to 150°C at low pressure ensuring that the surface being cleaned is not saturated or damaged.

Unlike traditional high-pressure washing, which can erode or damage materials, DOFF cleaning is safe, effective, and eco-friendly, making it ideal for historic buildings, stonework, and delicate surfaces. Using only water, it eliminates the need for harsh chemicals.

We use the latest model, the DOFF III from the manufacturers, Stonehealth which uses an average of 5 litres of water per minute. Between faster drying times and lower water consumption, this unit operates at a higher standard of efficiency. Sensitive stone masonry often requires a gentle approach, so less water also means less saturation and protection for delicate stonework.

All of machines are compatible for Hydrotreated Vegetable Oil (HVO), a smoke-free and efficient fuel alternative, supporting our eco-conscious clients in making sustainable choices without compromising performance.

Historic & Listed Buildings

We work with a number of Heritage Consultants and Councils to apply for permits and permissions for larger jobs (Listed Building Consent, etc). We can manage this process from the outset of any cleaning project.

Respecting Historical Integrity:

When maintaining or restoring historic and listed buildings, it’s important to use methods that comply with conservation guidelines and regulations. DOFF steam cleaning is widely recognised by conservation professionals and heritage organisations as a suitable method for cleaning and restoring historic structures because it respects the building’s historical value and avoids altering or damaging the original materials.

Maintaining Original Appearance:

One of the primary goals in preserving historic and listed buildings is maintaining their original appearance and structural integrity. DOFF steam cleaning carefully removes surface contaminants without altering the building’s original character, ensuring that the building’s historical aesthetics are preserved for future generations.
