Everytime it rains I notice a rotting smell (like mouldy food) rising from the cellar of my house. It's a mid-terrace so the cellar is not used but I'm not sure what the smell is or how to resolve, it rises throughout the whole downstairs of the property.
I've had a quick look and it does look as if there is some type of fungus or mould growing on the interior walls. Not sure whether I need to get the professionals in or can tackle the problem myself.
Would appreciate any help in diagnosing the issue or finding a company that can.
