A textbook example of how these snags should be handled and how a company builds and keeps a good reputation.Thanks Oz, for the reply. The company foreman was out this morning and would not sign it off as satisfactory. They are going to remove that section of wet wall and plasterboard. Reposition sink 50mm to the left and raise to 850mm with new stud work at the required height or where required and then reinstate everything and I have been told I pay nothing until it is done to my satisfaction and it has been signed off by him. He has intimated that he he will be present to oversee all works.
