Alternative?
Take many photos and document in writing that it was done properly.
There is indeed a smooth finish, even if it looks untidy.
In my opinion, it should also be continued on the outside to be able to glue the outer foil flatly.
This is done for an additional charge.
This amounts to about 400€.
There is a smooth finish, but it is done properly for 400€ more?
For the next crooked wall, you then have to pay fifty euros and if the screed is crooked it’s another 500€? Where is this going?
The construction manager has two options.
a) It’s okay as it is and nothing happens.
b) we fix it.
But to say at the beginning that everything is fine and now charge 400€ for correction? Sounds pretty shady to me.
