Unevenness in screed and parquet

Hello,

after the acceptance, we unfortunately noticed a few uneven spots in the parquet flooring in the new building, which are especially noticeable between rooms and at the transitions. We therefore suspect slight height differences in the screed, maybe about max. 1cm.

What do you do about that? Tearing out the parquet, grinding the screed, and starting over is a bad idea because we are already living in the place.

1) From when is this considered a defect that can justify a price reduction?

2) How much could realistically be reduced?

Best regards

Hello,

since when have you been living in it and since when have you noticed the unevenness?

Especially now that it is getting warmer, the parquet "expands." This means it also becomes wavy in places. 1 cm is absolutely within the acceptable range.

, we have been living here since March. We noticed the unevenness shortly after moving in. I therefore rule out temperature. Especially since it fluctuates more from room to room than from hallway to hallway. So, for example, from the hallway to the bedroom. More like a "level" issue...

What I mean is, if the parquet layer had taken a good look at the substrate beforehand, he could have ground the screed a bit more evenly.

I think 1 cm is the DIN tolerance

how can you measure it now?

Measuring afterwards is difficult. You probably have to lay a horizontal "ceiling" on top and then determine the distances.

yes, and how do you come to 1 cm???
