We bought our property 4 years ago. The survey passed the property with flying colours, no issues. Within 2 years we had cracks appear in our back walls, internally and externally. We told our insurers and they suspected subsidence so the cracks were monitored for a year. In this time our soakaways and drains were renewed (to eliminate this as a cause), and a large neighbour's tree taken down (said to be the cause). The loss adjusters did not really know what the cause was when we asked for a difinitive cause, but said it had stopped moving.
We moved out for 3 months and the walls were re-built internally and ceilings and walls replastered to half the house, back windows and doors replaced. We moved back in.
Now, over the past year, the cracks have re-appeared in the new plaster. It looks like the insurance company, the loss adjuster and the builder did not get to the bottom of the cause. Some of the cracks are in the same place.
What happens when subsidence repairs fail? We have let our insurers know and also the loss adjusters and we are waiting to hear back at the moment. We just don't know what the next steps could be and are a bit worried.
