Symptoms of Mold in Home Air

Feeling Unwell

• A good rule for checking for mold in the air is based on how you are feeling. When toxic mold is present, there are typically symptoms ranging from minor allergic reactions to severe burning of the mucus membranes. Symptoms can be highly individualized, dependent on immune system strength and tolerance to allergens. When air quality is affected by mold, residents may experience respiratory distress, nausea and headaches advancing to coughing up blood, neurological problems and even anaphylaxis. Most symptoms clear up when mold is removed from the environment, clearing the air in its departure, but some symptoms can remain, causing life-long health issues. Any evidence of mold should be taken seriously and removed as quickly as possible. In some cases, professional mold experts should be contacted to ensure complete and thorough removal.

Physical Evidence

• While you can't see the actual mold spores floating around the room, there may still be evidence of its presence. Mold requires a moist environment with organic matter on which to feed. Molds can thrive on virtually any surface, eating wood, paper and other popular wall surfaces. Stains on a wall, sitting water or moisture that does not go away indicate the potential for mold. Kitchens, particularly under the sink, bathrooms and basements are the most common areas where mold thrives. If possible, do not use an area in question for a day to allow it to completely dry out compared to typical daily use. Look for areas that are still damp and be aware of smells. When actual mold cannot be seen, these are good indicators that mold is lurking behind the walls, cabinets or beneath the floor.

Odors

• Mold has a distinct dank and musty odor. Some molds, particularly black mold, are even said to smell of urine. However, mold growing behind walls, floors and cabinets may not release a strong enough scent for detection. Any smells in areas of high moisture should be watched carefully. Air vents are another area where mold can lurk, so new smells coming from the air conditioning or swamp cooler should be evaluated. Mold does well in warm, humid environments, so dryer, cooler air is important in remedying a mold problem.
