Water stain on the wall. Suspected thermal bridge. How to proceed?

Here are some more posts from another thread that belong to the topic:

Thermal bridge? Sounds more like poor sealing - I don't think there's condensation there (but I am also an amateur). Is there anything in the contract about acceptance? I believe with the developer the transfer of ownership only occurs at handover, right? Then the first appointment would be voluntary. Defects that are hidden - and that certainly includes such errors (whether thermal bridge or sealing) are not considered accepted as far as I know even if not complained about.

But well, I am just an amateur.

If you suspect a defect, you should send the developer a formal notice of defects before acceptance. There are templates on the internet; if in doubt you really have to hire someone who knows about this. In short, you briefly describe the defect and demand that the developer fixes it. Do this by registered mail with return receipt (serves as proof later if needed).

That you are not allowed to bring anyone with you to the pre-inspection is not nice, but the developer has house rights. Whether it is still legal to refuse you the inspection I cannot say. If partial payments are due, you should also have the right to satisfy yourself of the construction status, of course you may hire a third party for this. ==> Consult a specialist lawyer for construction law.

Overall it all sounds very exhausting. Take the 1000 euros in hand, go to a specialist lawyer for construction law (with all contract documents) and get advice there (call in advance, ask about the costs for an initial consultation/contract consultation). The specialist lawyer can also recommend an expert who then reviews the construction description and conducts the preliminary inspection with you. You then do the acceptance together with the lawyer.

Do you have contact with other buyers? Is there already a property manager?

Make sure to get specialist legal advice before you possibly accept common property!

Was it really a water stain or perhaps just not fully dried plaster caused by a sinter layer?

A photo would have been nice.

Hello.
Attached is the photo. Not much can be seen here. On site, the stain was more visible.

That is not entirely correct. Based on the constructive component structure, it is only possible to show what was planned. What was actually executed is a completely different matter. If everything that was planned were always executed, fewer experts would be needed.

However, thermal bridges can only be meaningfully detected again in the cold season. Then, as an expert, you can also determine whether there is a defect based on the surface temperatures.

Hello. Thank you for the information. So would it be sufficient if I only complain about a possible thermal bridge etc. during the warranty period when the problem occurs? Or better yet, before acceptance based on suspicion? Thank you

I see little... well. So when drying the plaster we also had some slightly darker and other lighter spots - towards the end then really also pointwise.
