Look for signs of moisture caused by leaking pipes or water damage while conducting a visual inspection of your home. Brown stains on walls, baseboards or ceilings can signal a hidden mold problem.
Shine a beam of light along the wall to determine if mold is present. Observing the wall at an angle, rather than straight on, makes it easier detect mold growth.
Smell your home. A musty or earthy odor can be an indication that mold is present even when you can’t see it.
Pull up a small edge of carpet to expose carpet strips in areas of the home that have been affected by water. Rusty carpet strip tacks can be a sign of wet conditions caused by water or condensation.
Check under and around drawers in bathrooms where there has been excessive moisture as well as under and around furniture that has been exposed to water, moisture or dampness. Mold growth can also be found in places with poor ventilation, such as near a clothes dryer or in a bathroom.
Visually inspect wallpaper around windows for water stains where there is frequent moisture. If you suspect mold is present, pull back a small section of wallpaper to determine if there is mold growth on the backside of the wallpaper or on the wall.
