There are several indicators that should prompt you to investigate for mold. The most reliable are persistent musty odor, visible discoloration on walls or ceilings, unexplained respiratory symptoms that improve when you leave the home, and any history of water damage or known moisture intrusion. In Las Vegas, where surface drying happens quickly, you may have mold growing inside wall cavities without any of the visible cues that are more obvious in humid climates.
Visible Warning Signs
Visible mold can appear in many colors and textures: black, green, gray, white, or brown, with surface textures ranging from fuzzy to flat. Common locations include the caulking around tubs and showers, grout lines in wet areas, the corners of exterior walls, ceilings below bathrooms or mechanical rooms, inside cabinets adjacent to plumbing, and on walls with a history of condensation. Discoloration that is not explained by dirt or dust should be investigated.
Hidden Mold Indicators
When mold is growing inside walls or under flooring, the visible cues may be absent. The indicators to watch for are musty odor that you cannot attribute to a visible source, wallpaper or paint that is bubbling or peeling without an obvious cause, warping or buckling of flooring, and cold or damp exterior walls. In Las Vegas, I also see mold signs that follow the HVAC system, where spores distributed through ductwork , see what causes mold indoors cause respiratory symptoms throughout the house rather than localized to one area.
When to Get Testing
If you have any of the indicators above, or if you had any water damage event , see does water damage always lead to mold that was not professionally dried with moisture verification, a mold inspection is appropriate.
