Moisture control prevents mold and here are some useful tips to control and prevent mold in your home:

• Fix and clean roof gutters regularly.
• Keep the air conditioning drip pans clean and drain lines flowing properly.
• When there is water spills or leaks indoors, act very fast.
• When damp and wet objects or places are dried 24 to 48 hours after the spill or leaks, in many instances the molds will not progress.
• Always keep the indoor humidity low or for about below 60%, where 30% to 50% is an ideal relative humidity. Relative humidity is gauged with a moisture or humidity meter which is a tiny and cheap device where you can buy at many hardware stores between $10 and $50.
• Be sure that the ground slopes are away from the foundation of the building so that the water does not enter or collect around the foundation.
• If there is a condensation or moisture gathering on the windows, pipes, or walls, act on it quickly by drying the wet surface and lessen the moisture or the water source. Condensation is a sign of high humidity.

Here Are Things You Can Do to Reduce Humidity:

• Use air conditioner and/or de-humidifiers when it is needed only.
• Use exhaust fans or open the windows whenever you are cooking, run the bathroom fan or open the windows when you are taking a bath or showering, running the dishwasher, and the like.
• Open or put the appliances that create moisture including stoves, clothes dryers, and kerosene heaters outside if it can be done. These combustion appliances increase the humidity unless they are vented outside.

Things That Can Help Prevent Condensation

• Increase air temperature.
• Open the doors and/or windows, if it is possible, to improve ventilation or air movement and use fans when they are needed.
• Lessen the humidity.
• Cover cold surfaces like cold water pipes with insulation.
