"Bulging" window frames in new buildings - experiences?

Good morning everyone!

We are currently preparing for the handover of the house and are therefore looking for all large and small defects that we want to address or refuse to accept.

One thing is causing us great concern: the windows. As you can see, the groove in the lower part of the frame (inside) is curved upwards in an arc shape on almost all windows.

I have never seen anything like this and cannot classify it at the moment. Does anyone have experience with this and understand what it means?

Thanks for your help!

Best regards

Hello,

apparently the glass strips were cut 1-2mm too long here. Therefore, they bend upwards. The same can also happen on the sides and at the top, by the way. Either the glass strips are pressed back in during acceptance or they have to be shortened afterwards.

However, I cannot tell you how this will affect the acceptance.

Your answer relieves me. My initial research led me to heat damage, which would be plausible since it has been very sunny and hot in the last few days. That could mean a complete replacement of the windows, if I understood correctly.

Hello,

from the pictures, it doesn't look to me as if the entire frames of the windows have warped. Have you checked with a long spirit level whether there is also a bulge forming in the frame profile?

I still suspect that the glazing beads were made carelessly / too long. Nothing dramatic, which can't be adjusted with a good miter saw with a sharp blade or a file.

No, I haven't checked anything yet. I first noticed the bends yesterday while going through it and now I'm trying to form an opinion.

Next time I will check and also document exactly at which windows these "damages" are present.

Handover is in the first week of September...

Thanks for the help!

do you have an independent building surveyor with you, whom you can already go through everything with beforehand. He has experience with inspections and construction companies. You alone are just cannon fodder for them and will be coaxed, lied to, and talked down to about the state of the art until you sign off without any defects.
