Green (weeds) growing around gable end window


I have green weed/moss/micro shrubs growing in the joints of the the gable end brick work. The affected area surrounds a window and is about 4-5 meters of the ground. Does a weed-killer need to be used, or just grind and repoint?

I am assuming this is the reason I have damp wall (black dots) patches on the internal plasterboard in the loft wall?

Any advice would be appreciated.

Kind Regards,

I would suggest a repoint of the brickwork after raking out the joint and treating with a weed killer then a sulphide treatment.
The dampness on the inside will need completely dried out and checked for rot.

Without actually seeing the job it is hard to say at this point. Would suggest to ask at least two builders for the opinion and to find out what will be the best option for this problem.
