Silica, Dust, and ACM remediation

Like pests or biological growth (such as mould), air pollution and dust pose a risk to objects both indoors and outdoors. O’Sullivan Conservation and its team of qualified and well-trained staff are experienced with a wide variety of cleaning and prevention procedures designed to minimise the impact of dust and other air pollutants on objects of personal, cultural, and heritage significance. In-house services are also available for the removal of suspected Asbestos-Containing Material (ACM), which has the potential to harm individuals as well as objects.
