Interior window sills - What depth or overhang?

That's exactly what I suspect. It simply says window sills made of artificial stone in the construction service description.

You complain. If only stupid remarks come, you don’t pay for it. "We always do it that way"

Difficult, what does that belong to, cleaning?
Payments are made in installments anyway.

I would definitely complain about windows with Tussikrallen.

What are Tussikrallen?

So I am 25 years old and prefer the wide ones, I have also installed them myself. If it is not documented anywhere what should be installed, you can't do anything except hope for goodwill. I mean, he can't know whether you want narrow or long ones and since nothing was recorded, he might have assumed that you don't care. So the fact that he changes it on his own probably won't happen unless you pay for it.

Then I'll have myself admitted now. If I still have to hold on to that before, then I slowly don't know anymore. But I swear, if that's the case, then I'll personally tear those things out on Saturday, that's for sure.

Just a different question, how is the window even airtight? Isn't the connection tape for the interior plaster missing?
