House & Garden
Mold usually occurs in places that are moist or clammy, where a rather low temperature prevails and where the heating and ventilation is insufficient. Mold can also be caused by leaky walls. If you are worried that the roof or the façade are leaking, do not hesitate and contact an expert right away in order to prevent further damage. If you have rented the place, contact the property management so they can take care of the situation.
