Façade Cleaning Services

Preserving History with Precision

Biocide Softwashing:
The Gold Standard For Heritage Building Care

In the realm of façade cleaning, especially for esteemed heritage buildings, our Biocide Softwashing system stands out as the pinnacle of precision and care. But what exactly is Biocide Softwashing?

All cleaning techniques fall into one of two categories. Abrasive or Non-abrasive.
Abrasive methods remove the symptoms.

Non-abrasive methods treat the cause.

Hennessy-Ward Biocide Softwashing goes right to the cause of the problem, ensuring that the building remains untouched by abrasive forces. This method delicately yet effectively kills the cause of dirt, algae, moss, and other contaminants, and works with nature to return the façade to its original beauty, without risking any damage.

This is more than just a cleaning technique; it’s a commitment to preserving the authenticity and integrity of historical structures – Guaranteed.

The use of any aggressive method or chemical to remove layers of fungus and biomass will result in damage, no matter how gently it is done or what fancy name it is called.

Biocide Softwashing is the clear choice for restoration professionals. It’s a harmonious blend of gentle care and robust cleaning, ensuring that history stands tall, pristine, and undamaged.

This is achieved because we understand what is causing the problem. The use of abrasive methods will not only damage delicate surfaces but will only remove the symptom.
