Mold and mildew are likely to cause problems in a warm, humid climate. Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods. There are potential health effects and symptoms associated with mold exposures include allergic reactions, asthma and other respiratory complaints. The best way to to control indoor mold growth is to control moisture and eliminate or control sources of moisture and prevent condensation. Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation. In areas where there is a perpetual moisture problem, do not install carpeting by sinks, or on concrete floors with leaks or frequent condensation. If mold is already a problem in your home you can clean up the mold and fix the source of the water problem or leak to prevent mold growth. By by increasing ventilation reduce indoor humidity (to 30-60%) to decrease mold growth by venting bathrooms, dryers and other moisture-generating sources to the outside. Or by using air conditioners and de-humidifiers, and exhaust fans whenever cooking, dish washing and cleaning. Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth. Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are moldy, may need to be replaced. Pressure treated lumber uses a process that forces a water based preservative deep into the cellular structure of the wood providing long-term protection against rot, fungal decay and termite attack. There are also liquid products designed to control mold or fungus growing on the surface of paint, wood, tile, etc. A mold fogger saturates the indoor environment with the non-toxic mold-fighting very fine mist and coats all surfaces to eliminate existing mold and prevent mold regrowth. This is used in musty rooms to eliminate odors and is good for mold remediation and prevention in large or inaccessible spaces. Finish by cleaning up with a HEPA-filter vacuum and a HEPA-filter air cleaner, or at lease a dehumidifier. But fogging cannot, however, clear away actively growing sub-surface mold or prevent more mold from showing up when the cause of the problem hasn’t been solved. Even dead mold spores are allergens and potentially toxic. For just one room, rather than buying or renting a fogger and a dehumidifier, you may try using a canned mold bomb.
