Very messy parquet laying work - Is rework not possible?

If that's true, then one is unlikely to have any success in receiving a "dislike" compensation here. It shows again how far the execution "rules of technology" is from a "nice" execution. From 1950, basically.

So, as always, communicate what you don't want and what you want/how it should look. A mindset of "I thought that..." remains and is always a pain in the ass. In my experience, it causes communication problems and laziness to want to make it nicer as a craftsman.

Yes, I still see the responsibility partly with the craftsman. If we had not been asked yesterday "how would you like the joints - or preferably no joints?", then I would have had no idea that I had to address/decide that. Our installer also said that creating it without joints is a bit more laborious. And he said that this is not advisable if there are strong differences in room temperature or humidity, since wood naturally works. But he also said that they had already done the seamless version in many houses, and so far nothing had ever happened.

If you get a craftsman who simply does it according to the state of the art, no matter how it looks, that may be legally sound but certainly not in the customer's interest. As a customer, I would also be dissatisfied there. And for the craftsman, that leaves the unpleasant impression that he only does the bare minimum without much regard for how his "work" looks in the end.

Do you install it floating or glued? If glued, I would align it with the joints of the screed. Anything else would seem suspicious to me.

You can't say that in general. It also strongly depends on the type of parquet and surface treatment. I would never have oiled solid wood parquet installed on large areas without sufficiently large expansion joints, as it simply swells and shrinks. However, there is also parquet with an MDF core layer, which is more dimensionally stable. Varnish also slows down the absorption of moisture. (And I would never have it installed floating again. Currently, we are even considering having the parquet completely reinstalled because the springy floor in the dining room and hallway on the upper floor annoys us so much.)

We are getting JOKA Landhausdiele Country E7113, glued over the entire surface.
I rely on the assessment of the floor installer. Our contractor has never disappointed us so far, and the floor installer does the entire interior work including floors. Therefore, I trust that if he says it can be done that way. =)

You can only chuckle every time about the apparently freehand cut floorboards on "Picture3" made with a jigsaw. Don't they have a miter saw with them? Strange.

That's exactly how it looks. At the beginning, we had pictures here where I would have turned a blind eye. The bad spots only appear gradually.

What you see in the last two pictures is really total botching and must not happen when working with proper tools (miter saw, hand/table circular saw).

what exactly is included in the price of 25,000,-? My parquet installer laid/glued 150sqm of parquet including baseboards and including stair covering (same parquet). Without expansion joints at the room transitions and with Schlüter strips to the tiles. He charged 4,900,- euros for that :oops: It was three years ago, but the price of 25,000,- shocks me a bit...
