Hello everyone!
In my opinion, the plastering on our stairwell, as well as on some of our interior and exterior walls, is very poorly done (see pictures).
However, our construction company denies this.
Could you please give your assessment based on the pictures?
How would you handle this situation with the construction company?

Interior with rough wall texture, window on the left and open wooden shelf on the right.


White interior wall next to a window with a view outside to grass and trees.


Textured interior wall with uneven patches; window on the right shows garden and houses.

Which quality was agreed? Q2 or Q3?
Which quality level is it supposed to be? Q2 or Q3? What did you commission? @Sandra84?

The painter from the construction company came by and painted again. He left the house saying there’s nothing he can do if the plastering is so poorly done.

And these are brick walls. The plasterers are blaming the bricklayers.
Couldn’t the plasterer have just applied more plaster to even it out?
Why does the painter paint over it when he can see the base is in bad condition?

Well, now that the furniture is already arriving, it seems the problem is too late to fix. Did you inspect and pay for everything?

Given the extent of the issue, affecting all interior rooms and also the facade, I would have an independent expert come as soon as possible. They will tell you according to which DIN standard this is acceptable or incorrect. That way, you’ll have solid evidence to confront the contractor.

Whether Q2 or Q3, the DIN standards are so lax that there’s nothing you can do. I know what I’m talking about—I had the entire upper floor (it looked worse than yours) replastered at my own expense after moving in (had to).

Light from above is also grazing light. It either has to be completely diffuse or come from the front.
More than one centimeter (0.4 inches) difference would already be quite noticeable. There’s probably a standard for that, but I’m not sure which one.

Why is grazing light not allowed? I only notice such irregularities when light comes from the side. You can only check a car for dents if the lighting is right for it.

That’s just what the DIN standard says… It also specifies how uneven plaster can be – and that’s quite a bit. In our case, the walls were so crooked you couldn’t even fit baseboards properly… According to DIN: everything was fine

Yes, the tradespeople’s lobby probably benefited a lot from this.
That said, with a really powerful spotlight and if it’s dark, raking light is quite unforgiving. Even small surface irregularities become very noticeable. Maybe that’s why.
With glass, you usually have to stand quite far away, and minor scratches are only bothersome within the visible area; otherwise, longer ones are acceptable.
It’s even better for the masons. If I remember correctly, a wall is allowed to be off by 2-3cm (about 1 inch) per meter, so just 2-3%.
That’s why kitchens should never be ordered strictly according to the plan.
