Balcony door and window sills - defects in new construction

Definitely do not accept it like that! As described above, consult an expert for advice. Don't let yourself get discouraged

Engage experts and have the issues rectified where possible! Have you withheld security deposits?

My concern is basically not that the defects will not be repaired somehow, but that the quickest and easiest way will be taken in the repairs, and not the right one.

Therefore, also my questions regarding the seal and the window sills. If the defects are to be repaired next week, I wanted to know if the work was done properly.

@11ant surely knows something about the window.

I am a big fan of Austrian humor and therefore absolutely sure: this botch job has nothing to do with that.

My concern is basically not that the defects will not be somehow repaired, but that the quickest and easiest way will be taken during the repair and not the right one.

The (only!) right way here is: get rid of the junk! - this is irreparably defective goods, and furthermore installed without the slightest trace of expertise. Mind you, not inferior in the sense of discount quality – I couldn’t tell from the pictures here – but junk in the sense of incompetently processed and massively damaged.

If you already botch something like this, replacing a three-wing element with a two-wing and a separate single-wing element, it should at least be “professionally joined” with a coupling profile.

First of all, such a coupling profile might not even exist for the profile system used here (perhaps also discount junk?), and secondly it consumes a few centimeters in width which would then have to be deducted from the other elements. So that would already rule out making such a repair, because at least one of the elements would have to be replaced for that reason alone. NO seal can even remotely replace such a profile.

Furthermore, I have the impression that blunt tools were used for cutting here or the miter saw is misaligned, because the only proper gap dimension on a miter is "zero".

Basically, silicone or acrylic is only intended for joints if the installer knows the fundamental difference between a joint and a tolerance excess. That is by no means the case here (I’m missing the Mady who converts that quickly into Schillings *smile*).

I can’t imagine anything under a window sill at 170 cm height, but in my opinion the illustrated execution of a window sill clearly belongs on the outside: it usually doesn’t rain inside, so a drip edge that directs rain away from the plaster facade is unnecessary inside. I claim that in this respect AT and DE are the same when it comes to cultural idiosyncrasies.

I am almost certain that the window dealer in this case usually deals in something completely different.

Here even the most crooked pearls of the window INSTALLERS guild I have encountered so far have been far surpassed. Respect.

Wow. Even worse rubbish than feared. Botched is then still a praise.

Thank you very much for the detailed answer!

The apartments were not cheap (all cost between 3,900 and 5,000 per square meter), reputable construction company and all the materials used are good (so not discount store quality). And then the installation is botched like this.

Viennese humor is somewhat macabre... so it doesn’t get lost even in such situations.

The windows and terrace doors are from Internorm, so not discount store quality. I also took a couple of photos. The seals leak both at the top and the bottom.

In your opinion, are the terrace doors two elements that cannot be airtight as installed?

Two window sills are at a height of 170cm, since the windows on the ground floor face the sidewalk. I don’t know why the window sill on the inside has a drip edge. Maybe the developer prepared for the possibility that it will soon rain inside... not unlikely considering all the defects.
