Got someone in to do our dining room floor, and were pretty pleased with the result. They managed to level it as best they could despite one side of the room being a few cm higher than the other. Unfortunately, in the process of digging up the concrete hearth (which they then boarded over), the fireplace fell off the wall. It was apparently just balanced on some bricks. So now we'll have to redo the fireplace as well. On the plus side, I get these cool snazzy booties to wear while the floor cures.
