Hello,

is it normal or something you have to accept that the floors in the upper floor of a 12-year-old prefabricated house develop "dents"? When walking over them, I notice depressions, and the click vinyl flooring makes noises. In the dressing room, the wardrobes creak when I enter the room. Three rooms are affected.

Does anyone happen to have experience with this issue?

Best regards,
Oli

No, it is not normal for a floor covering to creak when you walk on it!
What is the subfloor made of?
Is it possibly a wooden construction?
I cannot imagine it being a mineral screed, as that does not settle over time in the walking area.
(Please provide a brief description of the subfloor)

Thank you for your response. They are cement-bonded particle boards that look like concrete slabs and were glued together at the joints, without underfloor heating (from Schwörerhaus). After 12 years, is there still any chance of remediation by the house company?

Of course, there is a wooden structure underneath since it is a prefabricated house.

Thank you for the quick response.
Just for your information: the term "prefabricated house" does not necessarily imply that the floor structure is made of wood!
Often, the floor slabs are made of precast concrete elements, which are later finished with installations, insulation material, and a mineral-based screed.
In your case, however, it is a wooden construction with fiber cement boards.
Your question about possible repairs shifts from a technical to a legal basis. Only a lawyer should provide an appropriate answer here; anything else would be mere speculation, including from me.
The same applies to the technical aspect, which I would have to personally inspect and open to give a clear statement.
Since fiber cement boards themselves are not prone to compression when walked on, it is quite likely that either the insulation layer beneath contributes due to its ductility, or the fiber cement boards, if mounted on wooden battens, did not have a suitable material thickness considering the support spacing. In that case, they bend (also due to material fatigue) under load, deflecting from the walking surface level.
This means that a proper answer regarding possible remedies can only be given after opening the floor structure and examining the causes.
