Varying Humidity Levels: remember that the humidity in some rooms, kitchens and bathrooms in particular, can be higher than in other areas of the home, thus encouraging condensation to form on the windows in these rooms.
Exposure: some windows in the home may be protected by other buildings, trees, etc., which form a windbreak while others are totally exposed to the wind and, therefore, colder.
Ventilation is the most effective means to remove moisture from your home. By exchanging some of the drier outdoor winter air for warm humid interior air, the moisture level inside the house will be reduced.
- Open a door or window for short periods to allow moisture to escape.
- Gas appliances produce moisture from combustion. Cooking adds even more moisture so be sure to run your kitchen fan while cooking. Vent the kitchen fan directly to the outside to achieve the desired effect.
- Showers are a high source of moisture. Keep bathroom doors shut and run the exhaust fan to eliminate moisture.
- Clothes dryers should be vented to the outside. Hanging up wet clothes to dry inside your home can add significant moisture to your home.
- Shut off the furnace humidifier and any other humidifying device in the home.
- If you have a fireplace, open the damper occasionally to allow moisture to escape.
- Free air circulation is important. Do not cover hot or cold air registers with furniture or appliances. Leave bedroom and bathroom doors open.
- Keep the temperature of all rooms at a minimum of 10 C (50 F), even if unoccupied. Condensation will occur in an unheated room.
- Wipe up any tracked in snow before it melts and evaporates.
