Hi sorry to bother u but my friend who lives on her own has just had cracks between cornices and walls repaired by a professional tradie a few months ago, and he said he used good quality filler which was moveable, she asked me why the cracks have opened again so soon which is rather disappointing to her, she is 77… This work was done just at the end of winter early spring. My reply to her was there must have been some great movement in her area such as a slight earthquake. etc I was wondering if this comment was correct or what would the reason be please … thanks for yr time Noelene
