Hello. I've noticed some irregular diagonal cracks in a first floor chimney breast. It looks almost as if it is cracking down and outward. They seem to be extending but as there has been a picture there for several years it is difficult to say for sure. The ground floor chimney breast seems fine with no cracks. Is it serious, how would I get it sorted and will be it be expensive/disruptive/depressing?
Thank you
