Cold from Damaged plasterboard wall corner

[Alex elephant]

Hi guys
We recently removed l skirting board for a new laminate floor, I have yet to add new skirting but I have noticed draughts coming from the chipped plasterboard on wall corners, in some places exposing the metal mesh underneath, please note picture b

what’s the best way to try and insulate the cold air that’s coming out and also for me to try and fix the plasterboard myself if possible

thank you guys!!

Not sure there would be much you could do, there doesn’t appear to be any large holes to block up.

I would just ensure the skirting is fixed firmly in place and the gaps caulked. Use filler for any remaining plaster damage that may be visible.
