"About 38 percent of homes have mold and fungus growth due to elevated moisture." (The American Society of Home Inspectors).
Basements and concrete slabs are the largest sources of moisture in your home. The pores in concrete do not only let in moisture, but they actively draw it inside by capillary action. The average basement lets in 18 gallons of moisture each day, several times more than your bathrooms and kitchen combined!
Molds and dust mites aggravate or cause allergies and asthma, particularly, in children. The incidence of allergies and asthma has doubled in the last decade, which has been linked to the increase in air-borne molds in modern energy-efficient homes.
Your basement is not the healthiest room in the house so you need to be careful and actually do something about it when you start your new basement remodeling project. The only effective way to control biological air contaminants like molds, fungi, dust mites, and bacteria is to control the cause. Your goal: eliminate the sources of moisture and reduce humidity in your basement!
A wet cellar can dramatically reduce the value of your home. Studies show that most people won't even consider buying a home that has water leaks. Selling a home with water leaks can easily result in as much as a 25% reduction in the sale price, if it sells at all.
Even if you rarely have problems with dampness or flooding, it's best to solve the problem completely before doing any remodeling work. Permanent solutions can take time to implement. A good place to start is to talk to a waterproofing expert.
Proper insulation is critical to creating a comfortable, dry basement. Besides keeping out the cold, basement insulation prevents condensation. The ground stays cool year round. It, in turn, keeps basement walls cool. When the warmer air in the room comes in contact with all those cool walls, it has to give up some of its moisture in the form of condensation. In fact, condensation is the primary source of the moisture that causes mold and mildew problems in basements. Effective insulation separates the warm air of the room from the cool walls, thereby preventing the moisture problems that stem from condensation.
