Specialists in the Exterior Cleaning of Buildings
Removal & Treatment of Red & Green Algae, Fungi and other contaminants on domestic and commercial properties
A newly rendered building looks great, unfortunately the reality is within a few years algae and/or fungi often appears on the surface of the render making the new render look old and dirty.
There is no need to paint the surface as this is costly and 99% of the time unnecessary. We can remove the algae and/or fungi from the surface usually without the need for cherry picker or scaffolding fees.
Upon cleansing, some faint grey marks can linger: If on a rain-washed surface, they tend to fade and disappear in the fullness of time: Up to 18 months.
In areas not rain washed, the marks have no mechanism to disappear, and a second visit may be necessary to remove lingering stains by brush, water, or an oxidising agent.
Our biocidal detergent is a high purity Quaternary ammonium registered with the Irish Pesticide Control Service and the British Health & Safety Executive.
