Excess Moisture: Causes and Cures

I came across this great article about excess moisture and the causes and cures and thought I would share it:

ause: Inefficient windows with extremely cold glass surfaces

Cure: Install energy-efficient windows and doors. High-performance windows, such as those made with Low E II coatings with Argon gas, make the most of the sun's heating rays during cold months and maintain a remarkable temperature difference between the indoor and outdoor panes of glass.

Cause: Inadequate ventilation of windows

Cure: Keep window coverings open during the day to allow air circulation and make sure patio doors have heat vents beneath them.

Cause: Moist air trapped in attic

Cure: Seal around indoor light fixtures to prevent warm, moist air from rising to the attic. Install soffit vents to prevent attic rot, making sure to keep vents clear of dirt and garden debris.

Cause: Radiator or kerosene heat

Cure: Use dryer sources of heat such as gas or electric furnaces.

Cause: Cooking and dishwashing

Cure: Vent stove range hoods and dishwashers to the outside. Cover pots while cooking.

Cause: Stale, damp air

Cure: Install an air-to-air heat exchanger to vent moist air outside. Some air quality systems recover up to 97% of the existing warmth and energy to heat incoming fresh air.

Cause: Showers and baths

Cure: Make sure bathroom exhaust fans are vented to the outside and use fans regularly.

Cause: Ironing, washing and drying laundry

Cure: Make sure the clothes dryer is vented to the outside and/or install an exhaust fan in the laundry room.

Cause: Dirt floor crawl spaces

Cure: Vent crawl space and/or cover dirt with plastic to create a vapor barrier that will prevent moisture in the soil from rising into the home.

Cause: Groundwater seeping through foundation

Cure: Install gutters, flashing and downspouts and grade dirt to channel water away from the home's foundation. (Minimum 6" slope over a 5' run.)

Cause: Indoor plants

Cure: Use small fans to circulate air.

Cause: Excessive humidifier use

Cure: Keep indoor air quality to optimum humidity levels. Hygrometers are available at most hardware stores, and can be used to measure home humidity levels.

Cause: Damp basement allows ground moisture into home

Cure: Running a dehumidifier in the basement can reduce musty odors and mold.

Cause: Unseasoned firewood

Cure: Minimize indoor firewood storage.

Cause: New wood, plaster, cement, and other building materials

Cure: Building materials contain a great deal of moisture. As soon as the heat in the home is turned on, this moisture will flow into the air and settle on windows and other cool surfaces. Plan for extra ventilation for the first few years in a new home or newly remodeled home.

Enjoy!
