They only tiled half the ground floor (thank god) so there are plenty of tiles left to assess for bowing etc. We’ll be doing the other half, will be interesting to see whether or not we do a better job with zero experience and a
tile levelling system .
As I said, I don’t know WHY I paid this guy, I never do that, i just wasn’t thinking clearly and was so relieved to be on the Home run to moving out of a single bedroom upstairs and back into our house. It’s cramped with 4!
Another tiler is coming out tomorrow to assess and advise. Will ask him to look at the tiles as you have all suggested all possibilities for such a lax looking job.
