Our house has several ties and historical cracks, and so we had a survey done before buying it to ensure these were historical. Reassured, we made the purchase. Alas, part of an end wall has noticeably become bowed over the past decade, and we discovered to our horror that an internal cellar wall (holding up a wall above and a chimney) has collapsed at some point since last Christmas. There are small cracks in a wall above the collapsed wall, and a bedroom door in that wall no longer closes! I think we might have subsidence. Does anyone have any experience of this? How is it officially diagnosed (hanging on to some hope that the insurance might cover remedial work before the house falls down)? Does anyone know anybody in northern Aveyron who may be able to advise us?
