High deposit request and uncertainties, Aalborg

From the document I received I see that the majority of costs come from waxing the floors, painting the walls and ceilings - written under "MALER". However, a landlord visited the apartment one day before we moved out to assess what condition the apartment is in, stating that it won't need painting. We have only been in the apartment for half a year, we have taken good care of it and we cleaned it extensively upon moving out. It is inadequate that we have to pay for all the unnecessary renovations such as painting the ceilings in the whole apartment - the ceilings were completely untouched additionally walls weren´t painted or penetrated by any nail.

Also, in the document, there is the expenses for cleaning, written under "Rengøring", which is not documented with specific prices, 18000 Dkk. As I mentioned before, we have cleaned the apartment in great detail before moving out, so how is it possible we have to pay for additional cleaning ? Furthermore, the craftsmen were changing one of the windows in the apartment just in the week after we moved out, therefore we don't even know whether they didn't influence the final condition of the apartment as well, which is very likely when there is construction work done on the building.

Another cost was 1000 DK for taking out two pieces of furniture, which I didn't manage to get rid off before moving out.Is the price of 1000 DK standardized for furniture removal or why does it seem so unreasonably high?
The price we paid for the deposit when we moved in was 4000 Dkk, now the landlord is asking for additional 3600 dkk for totally unknown unnecessary services, like mentioned cleaning, floor waxing, walls painting.

Please recommend some steps I can execute in order to avoid unnecessary expences. Have a nice day Thank you.
