Can I Get Mold In The Summer?

7/11/2018 (Permalink)

In general, mold grows well within the same temperature range that makes us feel comfortable, about 60 to 80 degrees. When warm, moist air comes into contact with cold surfaces, it can create condensation, since the cooler air can't hold as much moisture. Sometimes, humidity or dampness, or water vapor in the air can supply enough moisture for mold growth. Indoor relative humidity should be kept below 60 percent.  Ideally humidity should be kept between 30 percent and 50 percent, if possible. 

 In the summer, air conditioning can de-humidify indoor space. However,  if the system is too large or too small for the space it serves, the cooling system can create high humidity by cooling without removing water vapor. A properly sized and maintained system will dehumidify and cool a building. Learn more about the role of heating, ventilation and air conditioning HVAC systems in indoor environmental quality.

When there are cold surfaces in a building, water vapor can condense on those surfaces, just as water condenses on the outside of a glass of ice water. Insulation of exterior walls can prevent condensation and mold growth during the winter.

You should always be mindful of indoor sources of water vapor that can be problematic. Clothes dryers must be vented to the outdoors. Unvented gas or kerosene space heaters can generate enormous amounts of water vapor, as well as other air contaminants, and should be used sparingly and never as a primary heat source. Always run the bathroom exhaust fan when showering or bathing, and make sure the vent is exhausted to outdoors. A properly vented kitchen exhaust fan can remove steam created during cooking.

If you find you have mold growth in your home give SERVPRO of LaGrange Park/North Riverside a call at 708-240-4873.  We will make it “Like it never even happened.”
