I have a conservatory with a dwarf wall. The wall sunk by around 10mm on one side and mostly in the corner towards where it is supposed to be tied into the house wall. The conservatory company underpinned the area around 18months ago. They finally came back today to have a look at the damage that has been caused. The dwarf wall has come away from the main wall, the window ledge has dropped but not as much as the wall so there is a gaping gap where the wall has separated from the window ledge of which you can see daylight through. The floor has also dropped. He has filled the great big gaps between the walls and under the window ledge and have said they will come back to pack the floor.
My concern is is this the correct procedure for this. The damage seems a little extreme for just filling or am I being a bit over dramatic. Do I need to get an independent surveyor in. I have no clue in building work so a little advice would be great.
