Black mould is the most toxic type of indoor mould and poses various health risks. It's recognizable by its greenish-black hue and a potent, musty smell in the affected area. Black mould is primarily caused by category 3 flooding involving 'black water' laden with contaminants. This could include sewage water, rainwater, or seawater. However, black mould can grow simply because of high moisture levels, similar to other kinds of mould.
Detection of black mould can sometimes pose challenges; therefore, it's advisable to leave it to the trained eye of professionals. Experienced black mould removal services handle toxic black mould, ensuring you remain protected from prolonged exposure.
