Hello,

after the final inspection, we unfortunately noticed some unevenness in the parquet flooring in our new build, especially between rooms and at the transitions. We suspect there might be slight height differences in the screed, probably around a maximum of 1cm (0.4 inches).

What is the usual approach for this? Removing the parquet, grinding down the screed, and reinstalling sounds inconvenient since we are already living here.

1) At what point is this considered a defect that justifies a price reduction?

2) How much of a reduction could be realistically expected?

Good luck

Hello,

How long have you been living there, and since when have you noticed the unevenness?

Right now, as the weather gets warmer, the parquet is "expanding." This means it sometimes becomes wavy. A variation of 1 cm (0.4 inches) is absolutely within the normal range.

@HilfeHilfe, we have been living here since March. We noticed the unevenness shortly after moving in. I therefore rule out temperature as the cause, especially since it varies more from room to room than from hallway to hallway. For example, from the corridor to the bedroom. So more like a difference in "level"...

What I mean is, if the parquet installer had carefully inspected the subfloor beforehand, they could have leveled the screed a bit more.

I think 1 cm (0.4 inches) is the standard tolerance according to DIN.

How are you planning to measure it again now?

Measuring is difficult. Most likely, you need to place a horizontal "ceiling" above and then determine the distances.

Yes, but how do you arrive at 1 cm (0.4 inches)???
