The presence of asbestos, mould, or vermiculite poses a significant risk to your health. Professional decontamination is essential to ensure the safety of occupants and the value of your property.
DMG has the expertise and equipment necessary to carry out these complex decontamination projects.
How Can You Identify and Treat a Mould Problem That Requires Decontamination?
Mould can grow quickly in damp, poorly ventilated areas of your home. DMG offers mould decontamination services tailored to each situation, effectively eliminating the source of the problem and preventing its recurrence.

What Are the Risks Associated with Asbestos and Why Is Decontamination Essential?
Asbestos, once widely used in construction, is now recognised as a major health hazard. Inhaling asbestos fibres can cause serious illnesses, such as lung cancer.
Asbestos decontamination is therefore crucial to protect the health of your building's occupants.
