Why It’s White
White mold’s unusual appearance is caused by a lack of spore pigmentation. This is often a result of the type of materials where the mold grows. Unlike most fungal outbreaks, white mold doesn’t darken as it matures. Lab testing usually indicates a white mold sample to be cladosporium or aspergillus. It’s hard to tell the difference between this mold and ordinary mildew. White mold on walls looks very similar to the less harmful mildew which only grows on surfaces. Unlike mildew, white mold permeates porous materials ruining wood, sheetrock and even furniture.Confusion in the Basement
Chicago homeowners often confuse white mold in basements with crystalline efflorescence. Both growths thrive in damp environments, but efflorescence is actually a type of salt deposit left behind when moisture wicks through concrete. It doesn’t affect sheetrock or wood. Two simple tests can determine whether you’re looking at white mold on concrete or efflorescence salt deposits. 1. Lightly mist the area. If it’s efflorescence, the growth appears to dissolve. 2. Pull a small amount from the wall, and squeeze it. Efflorescence breaks into a fine powder. If a sample fails these tests, you’re dealing with a white mold outbreak that can quickly spread to things stored in the basement. Chances are good that it’s already growing inside walls and threatening the entire house.White Mold Health Risks
Is white mold dangerous? We’re often asked that question by concerned homeowners, and the answer is yes. Like all molds, its airborne spores can penetrate the eyes, lungs, and skin. If you or someone in the family suffers from allergies, white mold can make symptoms worse. Exposure to mold can aggravate existing conditions like asthma or cystic fibrosis. It can result in fungal sinus infections and bronchopulmonary problems. Even if you’re in good health, white mold in your home can cause itchy, watery eyes, persistent coughs and bouts of sneezing.What You Can Do
