I've had an extension done a year ago and the builder did a wonderful job, but now after the winter the drywall is pulling away from the brick wall and there is a slight crack. The brick wall has been plastered and painted as well, just for the record.
I can paint it over but the crack will reappear, so I'm thinking about something more elastic. What is the best way to fix this? Would silicone work? Or what about gloss paint, does that have enough elasticity in it?
This question is slightly different from this one which is more about a ceiling.
