Mold vs. Mildew Mold
The following actions can help prevent mold and mildew growth: Keeping humidity levels low, between 30- 50% Using dehumidifiers, fans and opening windows, especially during humid months Fixing leaky roofs, windows and pipes Ventilating bathrooms, laundry rooms, kitchens, basements and other damp areas Drying water-damaged areas within 24 – 48 hours Regularly inspecting building exterior for signs of leaks and other issues like cracked masonry, window frames and deteriorating flashing Testing for Mold and Mildew Research by the National Institute of Occupational Safety and Health (NIOSH) suggests that finding and correcting sources of dampness is often more effective at preventing health problems than counting indoor microbes. NIOSH developed a tool to help assess damp building areas and prioritize the remediation of problem areas. However, there are some simple ways to tell if a stain is dirt or a sign of a bigger mold problem: It has a strong, musty smell A drop of bleach lightens its color within 1-2 minutes It’s growing on warping, cracking or peeling material A source of moisture without much light is nearby
Fuzzy, raised appearance Darker shades of black, green or red Often confused for dirt Produces allergens that can trigger allergic reactions and asthma attacks Produces potent toxins and/or irritants Mildew White/gray appearance in early stages Turns brown Flat, powdery Small dots Causes minor respiratory issues Tips to Prevent Mold and Mildew Controlling moisture levels is the best way to prevent mold and mildew growth. Moisture meters can help detect moisture hotspots in ceilings, floors and walls. Mildew is a surface fungus that can be cleaned with a disinfectant cleaner, bleach and a scrub brush. Mold is often a sign of a larger issue that may require professional treatment. Unlike mildew that grows on the surface, mold penetrates the objects it lives on and eats away at their cellular integrity. It’s best to invest in prevention up front to help control mold and mildew instead of scrambling to remediate them.
