Mold in the apartment
Causes and Formation of Mold
Molds need above all moisture and nutrients in order to grow. Due to structural conditions or incorrect ventilation behavior, the relative humidity in the apartment can be high. If there is insufficient moisture diffusion to the outside, mold finds the best conditions. Particularly in winter, certain living spaces such as bedrooms and bathrooms or kitchens are more at risk than other rooms. Further information can be found in the guide to the causes of mold.

In addition to structural defects or third-party negligence, mold can in many cases be attributed to incorrect heating and ventilation in the apartment.
