From the ventilation blows into the apartment - what to do

We have a new building of 5 floors, a brick house.
The problem in the apartment is the following, more precisely in all apartments of the house - it blows from the ventilation to the apartment, but I suppose to pull it out. Accordingly, the apartment in the apartment is Dubar, it is very cold and humidity is high since we glued 2 ventilation ducts out of three with adhesive tape and paper.
He invited firemen, gave the conclusion that the pipes in the attic are poorly insulated, and so they say everything works correctly. I do not believe this, for the first time I encounter such oblique ventilation, plus as a consequence, water accumulates on the glass in a large room (two-room apartment 51 square) and flows down a liter per day onto the windowsill!
Specify what service you can invite, so that they give a real conclusion certificate, so that you can go to court, the developer says that everything is fine and we inspire ourselves.


The ventilation system is the property of all residents and it is logical that the management company must service it. This is officially stated in the statutory documents. More often than not, a constant pestering of the Criminal Code by their problem helps and the problem is solved. It is a long and painful journey, but the result is worth it.
If, nevertheless, nothing happens, try the option with independent expertise in the construction organization and the design company. And already with these results, try to go higher in the courts. Do not forget to save checks! If you win the court, you will be required to reimburse all the costs of the examination and costs.
