5-Star Rated Exterior Cleaning
Effective removal of black whisky mould staining from render, roughcast, stonework and masonry.
At Nutech Cleaning, we have over 20 years of experience in whisky mould removal and exterior cleaning. Whisky mould, often seen as dark staining on exterior walls and other surfaces, can affect the appearance of a property and become difficult to remove without the right equipment and treatment. We use a range of professional cleaning methods to tackle whisky mould effectively, including pressure washing, steam cleaning and soft washing, selecting the most suitable approach for the surface and severity of the growth.
For the best results, we often recommend combining physical cleaning with a suitable biocidal treatment. This helps remove visible mould and organic growth while treating the remaining biological contamination. Following the cleaning process, we can apply a high-quality biocide to help kill residual growth and slow regrowth, keeping exterior surfaces cleaner for longer. This additional treatment is strongly recommended where appropriate to achieve a thorough, longer-lasting result.
Our whisky mould cleaning service is suitable for a variety of exterior surfaces, including roughcast, stonework, render and other masonry finishes. Every surface is different, so we assess the condition of the affected area before recommending the most appropriate cleaning method. Our aim is to remove unsightly staining effectively while taking care to use a suitable approach for the material being cleaned.

Whisky mould is a dark, sooty-looking growth that forms on exterior walls and other surfaces. It typically appears as black staining and can become difficult to remove without the right equipment and treatment.
We remove whisky mould from roughcast, render, stonework and other masonry finishes. We assess the surface first so the cleaning method suits the material.
We use pressure washing, steam cleaning or soft washing, selecting the most suitable approach for the surface and the severity of the growth.
Physical cleaning removes the visible staining, while a biocide treats the remaining biological contamination. This helps kill residual growth and slow regrowth.
Regrowth is possible, particularly in conditions that encourage it. Applying a high-quality biocide after cleaning helps slow regrowth and keeps surfaces cleaner for longer.
It depends on the surface and its condition. Where a gentler approach is needed, we use soft washing or steam cleaning instead.
Results depend on the surface, the severity of the growth and how long it has been there. We assess the affected area and explain what to expect before work begins.
