DOFF is a steam-based stone, brick and graffiti removal cleaning system. It’s unlike any other steam system and can achieve temperatures of 150°C at the nozzle end. The operator is able to vary the temperature and pressure to remove either many types of paint, biological matter or dirt build up from years of weathering.
During the restoration process, stonework or concrete may require cleaning in order to be fully restored to its former glory – this is the process of DOFF cleaning.
A lot of work goes into the restoration of historical buildings, to ensure that heritage sites maintain the same imposing outlook today as they had on the day they were first erected, a method we have used time and time again.
Historical building restoration not only preserves high-value buildings for the future, it also preserves our country’s past. As a country, we have such a long, rich and detailed history and these buildings reflect that. They are the visual representation of our history; a testament to the architectural prowess of our ancestors. For that reason, allowing these buildings to fall into disrepair is, ultimately, to disregard all of that history and the lessons we can learn from it.
