Painters did not cover the windows - endless plastering work

My response referred primarily to YPG, which had no chance of reprimand.

we have now started cleaning, 2 hours per window... We'll be busy for weeks :-/

Why YOU? - I would drag them back to their disgraceful crime scene by the ears, and afterwards they might have to write a hundred times: Painter's tape is right next to the checkout at Bauhaus.

Complain and insist on removal.
Ours were also so dirty.
Did you build with GU?

No, everything is subcontracted separately. I'll give him a call. But that's how it is, boss is a friend of an acquaintance... You have to be a bit diplomatic about it.

Will still be similar, the cause must eliminate the damage. It’s not just the working hours, but who pays for scratches.

If the service or the painter was tendered or commissioned according to [VOB], he is, in my opinion, obliged to protect the other trades.
