Prevent Mold from Developing

Q. We live in a 10-year old development.One of our neighbors is having a major mold problem. Our house doesn't smell moldy or anything. What can we do to stop that kind of probelm before it starts?

A. Although musty odors could indicate excess moisture or mold in your home, the lack of odor doesn't mean there may not be a problem down the road. Here are 10 recommendations to keep mold out of your life:
1) Watch for condensations, wet spots and leaks. Clean and dry within 48 hours, and be sure to repair the source of the moisture problem as soon as possible.
2) Prevent condensation by increasing the surface temperature or reducing the moisture level in the air. The former can be accomplished by adding insulation or finding ways to increase the circulation of heated air. To reduce the moisture level, repair leaks, increase ventilation and/or use a de-humidifier where necessary.
3) Keep heating, ventilation and air-conditioning drip pans clean. Make sure they're draining properly and unobstructed.
4) Vent moisture-generating appliances (such as dryers) to the outside.
5) Limit indoor humidity to below 50 percent relative humidity, ideally 30 percent to 50 percent. This means running the air conditioner or the dehumidifier during humid summer months. In winter, mold can grown on the interor surfaces of exterior walls. An air moisture level below 35 percent relative humidity at 70 degrees Farenheit can prevent this from happening.
6) Perform regular heating, venting and air conditioning inspections and maintenance per manufacturers' instructions on the units.
7) Provide proper drainage to the outside, and slope the ground away from the home's foundation.
8) Avoid storing organic materials such as paper; books and clothes in humid locations.
9) Use ventilation fans in the kitchen and bathrooms when humidity is high.
10) Exercise extra care in cleaning up after flooding or water damage. Be aware that some materials may have to be discarded and replaced after a major soaking.
