The guys have just left and they have made a big difference. The big cracks in the wall plaster have closed up (a few v new small ones have appeared, as Lee warned me about) and importantly, all the doors now open and close. We can now do a bit of plastering and painting knowing that the walls are stable. We will also have to replace our shower screen door because it is now out of square. I think the guys repacked about 6 stumps.
