Could be guttering related, could be hose pipe related? Whether it is or isn't, get the gutter fixed.
It could just be a section of wall that doesn't get much sunlight or is in shadow from the hose holder thing and so moss will more likely grow there if it doesn't dry out. A wall with moss on it will possibly retain more moisture as that is was moss does. You can get rid of moss with vinegar.
I’ve just noticed this on my house. There’s no damp anywhere else, nothing appears to be leaking. The one thing I think it could be is there is a part of my guttering that has become I clipped and it drips a lot when it rains. Or could this be something more sinister???
