Condensation in new homes

Condensation, or the appearance of moisture that occurs when warm moist air comes into contact with a colder surface, is most prevalent in new homes, especially during the first year.  This is caused by the large quantities of water used to build the new home, from the concrete foundations to the paint on the walls. As this water evaporates, and the drying out process occurs, the moisture takes the form of condensation on interior windows.  Proper ventilation is the safe and steady way to reduce indoor humidity, condensation, and mildew.

  • Ensure that the clothes dryer is properly vented to the outside and that the vent is clear.
  • Kitchen, bath, and utility exhaust fans should be used to carry moist air outside.
  • Adjust the registers to maintain even temperatures throughout the home.
