A problem with my home A big problem I had was mold. It was the first summer since I moved in. I smelled something bad in my home and noticed it was from mold on balcony wall. During the rainy season, the wall was covered with mold. I searched solutions and tried to get a hold of the situation. First of all, I purchased a mold cleaner to remove it. It took several hours to clean everything up. However, it couldn't be a fundamental solution. It grows again in warm, damp air, So I ventilated the room regularly, even twice a day. In the summer, I left the window open to reduce temperature difference between indoors and outdoors. By doing this, I realized the importance of ventilation and now I pay extra attention to mold.
