Hello,
we are somewhat concerned about our future parquet flooring and hope to find some help here.
In our apartment, a 2-layer engineered parquet will be installed. After seeing the installed parquet in another apartment, we are worried about the installation in our own.
The planned installation details are:
Material: Oak parquet (490*70mm (19*3 inches) with a thickness of 11mm (0.43 inches) and a wear layer of 3.5mm (0.14 inches))
Installation pattern: Herringbone
The issue is the uneven transitions between the individual planks in a row. In the other apartment, the height difference between the planks was very noticeable both visually and to the touch. It is estimated to be about the thickness of a credit card. Our concern is that this could cause people to trip (for example, with felt pads) or even injure themselves when walking barefoot.
On the manufacturer’s website (see above), it states “extremely precise fit” – so should this problem arise during installation?
The difficulty is that neither the construction and equipment description nor the apartment certificate define any criteria.
What tolerances would apply in this case?
Is it possible to request or agree on a higher-quality installation?
Can this issue be reduced afterwards? (Without a full sanding and refinishing.)

In our apartment, a 2-layer engineered oak parquet is going to be installed. After seeing the installed parquet in another apartment, we are worried about the installation in our own place.
The flooring to be installed is:
Material: oak parquet (490*70mm (19.3*2.8 inches) with 11mm (0.43 inches) thickness and a 3.5mm (0.14 inches) wear layer)
Installation pattern: herringbone
The issue is the transitions between the individual planks in each row. In the other apartment, the height differences between the planks were clearly visible and noticeable. We estimate it to be about the thickness of a credit card. Our concern is that this might cause people to catch (for example on felt pads) or even injure themselves when walking barefoot.

The difficulty is that neither the building and equipment description nor the apartment documentation defines any tolerances.

Is it possible to demand or agree on a better installation?
Can the problem be reduced afterward? (Without completely sanding down.)Are you sure the height difference remained even after the final sanding?Surely the specialist for this trade @KlaRa can provide answers...

Are you sure that the height difference still existed after the final sanding?This is prefinished parquet flooring, where the finish is already applied to the strips. It is simply installed (glued down) and then it’s done. Otherwise, prefinished parquet can be sanded once or twice, but that isn’t done after installation — only after extended use.
We have installed engineered hardwood flooring several times before, and it always fit perfectly, meaning it was just as level as you would expect from laminate. I would never tolerate such unevenness; in that case, I would rather choose a different manufacturer. If the flooring is lacquered, it must be perfectly flat, otherwise moisture can seep into the unprotected edges. Only with traditional hardwood flooring are such edges normal, as the floor is sanded after installation.

small update:
Today, we were able to inspect a few boxes of the materials and found that everything fits together very precisely. The rods all matched well, with only very small gaps between them.
Some rods were slightly bent (2 to 3 mm on 50 cm (20 inches)), but this should be resolved during gluing.
Otherwise, I suspect that the work in the other apartment was poorly done or inferior materials were used.
So, we’ll wait and see how it looks in our apartment after installation.
