So, here’s an update as well.
I’ll just quote myself:
I will probably really take out the windows and do it with my father-in-law.
In the end, I’ll get all the windows in RC2 for the amount of the credit (which automatically means better sound insulation) with external roller shutters on the upper floor and venetian blinds on the ground floor.
The credit was surprisingly high and I was able to get significantly more content for almost the same price through my father-in-law’s former employer.
Now, a different question:
What do you have to pay attention to content-wise for the handover?
My father-in-law said that rough construction dimensions of the openings are mandatory, and smooth finish. Something else?
I’ve already clarified with the general contractor that there will be a construction break until the windows are in and that they will take it over again afterwards. From reading the forgotten connection I’m a bit cautious, so is there a DIN or something else that says which trade has to carry out which work?
Thanks and regards
