Mold in walls can have several negative effects on indoor air quality and the health of the people living in the space. Here are five common negative effects of mold in walls:
Respiratory problems: Mold produces spores and other chemicals that can trigger respiratory problems in people, especially those with asthma or allergies. Prolonged exposure to mold can aggravate respiratory symptoms and lead to respiratory infections such as sinusitis and pneumonia.
Allergies: Mold spores can trigger an allergic response in some people, which can cause symptoms such as itchy eyes, runny nose, sneezing, rashes and difficulty breathing.
Unpleasant odors: Mold produces an unpleasant, musty odor that can be difficult to remove. Even after the mold is removed, the odor may linger in the room, which can be unpleasant and even annoying to some people.
Structural damage: If mold is allowed to grow unchecked on walls, it can damage the structure of the wall and weaken it over time. This can result in the need for costly repairs and in some cases, replacement of the entire wall.
Aesthetic problems: Mold on walls can make walls look stained and unattractive. Even after the mold is removed, stains or discoloration may remain on the wall, which can be difficult to remove. This can diminish the aesthetic and monetary value of the property.
