Terrace roofing profile incorrect

mh, well the thing is imho anything but clear. Open defects must basically be reported immediately. That means practically within a maximum of 14 days. Sure, you can understand the approach of trusting the supplier and ordering glass based on their measurements. But it would have been clearly better to actually measure with a tape measure. I have no idea how a court would decide here. How 'obvious' is the absence of 10cm in profiles of almost 5m?

Our neighbor recently had such a kit of the truck with forklift delivered to the property. Everything was nicely sealed in foil in a 4-5 meter long box. I hardly believe that you could have recognized the 10 cm from the outside. You would have had to unpack everything and then pack it securely again afterwards. But do you do that if you don’t want to assemble it yet? The OP didn’t even notice it during assembly. So the defect couldn’t have been that obvious.

Well, that is clear. On the other hand, the supplier can't do anything about the fact that it was only assembled after a year. If something had been said right away, he would certainly have made improvements. Does the time elapsed now make a decisive difference? I don't know. A court could also take the position that re-measuring was part of the required diligence, especially with regard to the fact that it was not supposed to be assembled immediately.

As a private buyer, you are not obliged to complain immediately. This only applies to merchants. Since this concerns a material defect and not a malfunction, I would personally see the seller as responsible as a layperson.

Shortening VSG by 10 cm should be no problem for any good glazier, according to your description the cut edge is the short side.

Hello marko1673
I see it the same way.
I have already contacted the company that supplied the glass. Pick up, shorten, and bring it back. No problem at all. I just want to push these costs onto the supplier of the profiles. And that’s where it gets tricky. They are playing dumb at first. As soon as they realize that the dismantling is no longer possible, they will offer to exchange the wrong profiles for the correct ones.
It’s really a pity. The quality and prices of this company are top. Only the service is terrible. A bit more customer service and I would recommend the place unreservedly.
The question is, can I sue for the coverage of the glass cutting costs? A dismantling would cost over 10,000 euros. Cutting the glass costs between 300 and 400 euros.
