We've all seen it, the ugly, insidious, black stain on a wall which is the trademark of black mould. It loves cold, dark, damp places and can often go undetected if it is somewhere out of sight. But, if you are suffering from health problems such as aches and pains, respiratory issues, allergies, brain fog to name a few, it might be worth checking your house/work for black mould. Frequent exposure to the mycotoxins released by mould can really damage your well being.
