Common problems
- The plaster sounds hollow and crumbles, but it is unclear how much of it has to come off
- The old tiles are laid on thick mortar, and an uneven base appears underneath
- There are pipes and cables in the wall with no plan showing where they run
- Rough work cracks tiles and plaster in neighbouring rooms or in the neighbours' homes
- It is unclear whether the wall that is in the way is load-bearing
