It is not unusual to smell odors during the drying process. Increased heat and humidity can also lead to increased odors that may be coming from the drying building materials, or dormant spill and accident areas. Do not confuse these normal odors with the odor of mold. As the drying process continues and humidity levels drop, you’ll notice these odors disappearing on their own. Deodorizers are often used to minimize these effects as well.
