What Causes
High Indoor Humidity Levels?
High
moisture levels are generated both indoors and outdoors. When moisture
levels are generated outdoors, they will eventually make their way indoors.
External Sources of Moisture.
Excess
moisture may enter a home externally several different ways. A leaking roof
will cause water to drip from above or water may enter a house through a
basement or crawlspaces. Moisture can enter a crawlspace / basement due to a
high water table, defective gutters, or through dampness in the soil.
Moisture may cause biological growth to proliferate indoors, often in
well-hidden spaces. This "hidden" growth will allow mold spores to be
released into living spaces by way of natural air currents.
Moisture problems that persist over extended periods of time will eventually
decay and lead to the rotting building materials, which will then threaten
the overall integrity of a home and the occupants overall health.
"The way to control indoor
mold growth is to control moisture.”
The U.S. Environmental Protection
Agency
Internal Sources of Moisture.
Moisture can be generated indoors from people and their daily activities
such as breathing and perspiration. Even an individual at rest will release
close to a quart of water per day.
Indoor sources
include:
Preventative procedures such as regularly
monitoring the RH levels and the use of a dehumidifier, especially in
"hidden" areas, will help catch moisture problems before mold growth becomes
extensive and damages the home, or even grows at all.
