Relative Humidity and Your Home
Unless you live in an arid climate, periods of high humidity create a myriad of problems for structures and people. Symptoms of high humidity would include:
- A musty odor in your home, and/or basement and crawl space
- Allergic reactions to mold and/or dust mites
- Visible mold growth in your home, basement, and/or crawl space
- Cupped wood floors
- Feeling “sticky” or “muggy”
- Visible condensation/water stains
- Peeling wallpaper/blistering paint
What Should My Relative Humidity Be?
Every homeowner should own a hygrometer that measures temperature and relative humidity (RH). The ideal relative humidity for health and comfort is about 40–50%. In the winter months, it may have to be lower than 40% RH to avoid condensation on the windows.
