My grouting has gone black, is it safe?

Black mould is not uncommon in areas with a lot of moisture. It doesn’t pose a catastrophic risk, but care should certainly be taken to keep children and animals away from it. It’s nothing to panic about, but we’d recommend getting a professional to take a look as soon as possible. In most cases we are able to neutralise and completely remove black mould, as well as offering practical advice on how to stop it coming back.
