Hi

The house we're moving into has a crack running from the window fram
to the skirting in one of the bedrooms:-

The surveyor checked it out and said it was cosmetic and there is no
corresponding crack on the outside of the property.

I want to avoid reskimming this particular room as there is no other
damage. Could someone recommend the best way to do a neat job of
repairing this?

That isn't a plaster crack, it's in the brickwork, something below this
window has moved in the past or is still moving, has there been any widening
of doors or other structural work carried out below it?
