ᐅ Damaged New Interior Doors – Defect Resolution

Good evening everyone,

I had four new interior doors installed, including frames. Altogether, there are 15 dents or paint damages. One door has already been repaired once (a chip on the corner was repainted, and a 15cm (6 inch) by 15cm (6 inch) area was sanded and repainted, including some paint runs).
The craftsman refuses to replace the door panels (returning them to the supplier should not be a problem, right?). He wants to fix all the dents with a paint pen and claims that this is standard practice. Could someone tell me if this is really a common way to remedy defects, preferably with a reference? Additionally, he wants to do further work on the doors in his workshop. I would be very grateful for a quick response! Best regards

No, it isn’t. The guy is insured for that kind of work.
Removing and reinstalling is actually less work than taking it along and refurbishing it, at least the door panels. He can repair the frame and offer a discount.

Exactly, I would just throw him the rest afterwards.

I've never seen anything like this before. What kind of doors are these? Are they covered with such a thin laminate?
The lip edges are amazing.
And yes: I'm familiar with the practice of touching up tiny scratches on windows with a paint pen. This was done on our front door as well, but since it has a higher value, a professional painter from the company was called in. Afterwards, you couldn't see any damage at all.

First of all, thank you for the responses. I agree completely; he does not see it that way at all. I now suspect that at least partly no new materials were used, and that is why he is refusing to accept a return. Is there a standard, like a DIN or something similar, for "touching up" with a paint pen?
By the way, the doors were not cheap at all, so I am quite shocked because of the quality.

I would not accept this as new goods.
