Fogging: If apartments are suddenly black again and again it happens that within a very short time, sometimes even overnight, the entire flat is coated by a soot-like film. Duke Realty gathered all the information. The real estate portal myimmo.de explains what it is this peculiar phenomenon of fogging and what tenants should pay attention. If ceilings, walls, floors, and curtains overnight by a soot-like lubricant film are covered, experts speak of fogging. In contrast to mold, no harmful damage emanating from this surface, however. The causes are still not fully known. However, there are some frequently recurring concepts: as fogging occurs mainly within the heating period and in about 70 percent of cases apartments are affected, in which women live. So far could not be clarified even still, why only certain buildings and homes of this problem are affected.

Because the phenomenon is not known, since the market offers eco-friendly products, Experts here see a possible cause. The organic plasticizer used in building materials such as plastic floors, colors, wallpaper, and adhesives, emit often over a long period. In the winter months, where increasingly heated and usually less aired, these fumes then settle on the cold walls of the apartment. The fogging is favoured probably also by heavy smoking and poor heating performance. The frequent use of perfumes, scented oils or incense as well as cleaning and care products seems to favor fogging. Who refers to an apartment for rent and contractually uses the leased property, can assume in the majority of cases, that the owner must bear the costs of renovation in fogging.
