Moisture & Mold Prevention & Control Tips

1.
Act quickly if you see moisture or condensation accumulating on windows, walls, or pipes. Immediately dry the wet surface and reduce or eliminate the source of moisture or water. Condensation is usually a sign of high humidity.
2.
Indoor humidity should be kept below 60% of relative humidity. An ideal range would be between 30% - 50% of relative humidity, which can be measured by using a humidity or moisture meter. These meters are small, relatively inexpensive, and can be found at many different hardware stores.
3.
Ensure air conditioning drip pans are kept clean and the drain lines remain clear for proper flowage.
4.
Take necessary steps to ensure the ground slopes away from the building foundation in order to avoid collection of water around the outside edge of the foundation.
5.
Clean out roof gutters on a regular basis and repair if needed.
6.
Act quickly when water spills or leaks indoors. In most cases, mold spores will not grow or reproduce if wet or damp areas or items are completely dried after the first 24 – 48 hours.

Actions that will help to reduce humidity

Open windows or use exhaust fans whenever cooking, running the dishwasher, etc. Open the window or turn on the bathroom fan while showering.
De-humidifiers and air conditioners should be used whenever needed.
Appliances such as stoves, clothes dryers, and kerosene heaters should be vented to the outside whenever possible.

Actions that will help prevent condensation

Cold surfaces such as cold water pipes should be covered with insulation.
Increase airflow and ventilation by opening windows and doors, and use fans as needed.
Increase air temperature.
Reduce the humidity.

Hidden Mold

As mentioned in earlier sections, biocides are elements that have the ability to kill living organisms. Using biocides or other chemicals that destroy organisms is not recommended as a common practice for mold cleanup. Biocides should only be used in rare instances using professional judgement. If you do choose to use biocides or disinfectants as part of the mold cleanup process, be sure to ventilate the area and exhaust the air to the outside. Be very careful never to mix chlorine bleach solution (a biocide) with other cleaning solutions or detergents that contain ammonia, as the mixture produces toxic fumes.
You must take caution when investigating hidden mold problems, as this may be difficult and can involve disturbing potential locations of mold growth. An example of this would be removing wallpaper that leads to a massive release of mold spores due to mold growth on the underside of the paper. If you believe you may have a hidden mold problem, it is best to contact an experience professional before trying anything on your own.
Many times a building may smell moldy which causes you to be suspicious of hidden mold, but you cannot see the source. You may also suspect hidden mold if you are aware of previous water damage and residents are reporting health issues. Unfortunately mold can be hidden in many places, such as underneath wallpaper or paneling, the top side of ceiling tiles, the back side of dry wall, the underside of carpets and pads, etc. Some other possible sites of hidden mold may include areas inside the walls around condensing or leaking pipes, the surface of walls behind furniture where condensation forms, inside ductwork, and in roof materials above ceiling tiles where there may be roof leaks or inadequate insulation.
