Hello
In our house, 60 m² (650 sq ft) of tiles were replaced two years ago. Tiles were glued directly onto existing tiles, with a primer applied to the old tiles and tile adhesive applied after it dried. The installation looked really good; only in one or two places was there a slight edge, meaning one tile was slightly raised. Now, after two years, several edges are visible, and the tiles seem to be shifting. Is this even possible? It shouldn’t have been like this from the start; otherwise, we would have noticed it.
The company has been closed for 1.5 years, the master craftsman is retired, and there was no successor.

Tap to check if it sounds hollow; otherwise, lift it and see what’s going on.

Hello questioner.
What "tomtom79" suggested is definitely worth trying.
You could gently tap the tiles with the back of a knife; this will help you hear whether, and if so to what extent, the tile is hollow underneath.
If the original tile installation, which according to your information was done only 2 years ago, was an official contract (not just "help from a neighbor"), then the warranty period should not be affected by the business closure. Certainly, this is a legal matter that I cannot answer as a non-lawyer. However, I would be quite surprised if valid claims could not be enforced by having a third party fix the issue and shifting the costs to the former company owner (who remains liable).
Best regards, KlaRa
