Not one we deal with am afraid , as others have said the correct cause of the problem is the most important. Most of the work i deal with is a result of trees on clayey soils and drainage problems , or poor construction. Not sure of the area, so couldn't advise on the local strata , neil forrow am sure could help.
However it is not uncommon to come across propertys whic have been incorrectly diagnosed and repaired by others in the industry. Have all the cracks been repaired? If not do they look fresh, ie sharp edges, or old contain debris , warn edges etc. Where are they located on the building? Are there any monitoring records?
