The tiles in the hallway and kitchen are glued to particle board, with regular floorboard underneath. We want to put new tiles in both rooms. If we level the floor and put new tile on it, we will end up too high and the doors won't fit anymore. Also, we will have a 3 cm difference with the other rooms. I tried knocking down the tiles, but only a few corners are chipped off, and the particle board is also damaged. I would also like to remove the board.
What would you do? Take it apart piece by piece?
