Is this black mould?

[LifesTooShortYOLO]

Noticed this around our door frame today is it black mould? There is just a small area.
And if so is it dangerous?
How can I get rid of it?
Thanks

You need black mould remover and a damp cloth. Make sure the area is ventilated if you can.

If that is an external door, check the external sealant. I'm guessing it's failed so there is now a gap for moisture to get in. Fairly straightforward to remove the old sealant and replace

HG mould spray is fab. Figure out why it’s damp and sort that as well to prevent it coming back. Might just need better ventilation (a window opening more often) or like PP said some sealant.
