Controlling Indoor Moisture & Humidity



Humid air and damp surfaces in your home can lead to bad odours, mould and mildew, or even damage to paint, wallpaper or furniture. Your best bet for controlling moisture buildup is minimizing cool surfaces and reducing humidity.
 
Storm doors and windows minimize cool surfaces in the winter by separating the interior from the cold, outside air. Double and triple-pane windows also insulate interior glass from the cold. Opening drapes and blinds in the winter allows warmth to reach the interior glass. Some condensation may occur, but the improved circulation makes it less likely to accumulate. Gas and electric furnaces reduce humidity with dry heat. Keep registers open and unblocked to allow for good airflow, and have the systems inspected and serviced regularly to make sure they’re functioning properly. Caulking and weatherstripping prevent humid air from entering a home and also reduce the air exchange that allows moisture to move out of the house. Bathroom exhaust fans, dryer exhausts and ducted kitchen exhaust hoods that vent to the outside will remove moisture created by showering, bathing, drying clothes, washing dishes and cooking.
