Is Bathroom Mold a Health Risk or Indoor Air Quality Problem?
Allergenic bathroom mold: Our photo at left shows the most common place to find mold in a bathroom, on the tile grout or caulk. Usually this mold is a member of the Cladosporium sp. group, often C. sphaerospermum – among the most common molds found, and possibly allergenic. The total area of mold in this case is trivial and unlikely to be harmful to anyone. It is primarily a cosmetic issue. A close up of this bathroom mold on tile grout is shown at below (left). There is no need to perform a mold test to identify small areas of mold such as those shown here. Just remove the mold and correct the conditions that contribute to mold growth. Whenever cleaning mold, especially when opening a wall or ceiling cavity where you have found leak damage, remain alert for the discovery of a large moldy area (more than 30 sq.ft.). If a large area of mold is discovered, stop work, seal off the work area, and consult a professional. See MOLD TEST REASONS for details.
