5 More Questions Answered

How do I know if my humidity gauge is accurate?

Dampen a towel (not dripping wet, but good and damp), then wrap the hygrometer in the towel for 30 to 45 minutes. Then unwrap it and read the humidity (quickly). If your hygrometer is perfectly calibrated (few are) it will be reading exactly 100% humidity.

Why is my crawl space so humid?

Some people find this hard to believe, but when you bring outdoor air into the crawl space, the relative humidity actually increases. ... Cool air cannot hold as much moisture as warm air, so the air that enters is now closer to its saturation point (which we call the dew point).

Can crawl space humidity be too low?

We speak of lowering relative humidity, but it can actually become too low. For example, if the moisture in your wood is lower than 5%, the wood will begin to dry out which isn't good either.

How do you know if your house has high humidity?

How to gauge if your indoor humidity is too low or too high?
  • Place two or three ice cubes into a glass, add water and stir.
  • Wait three to four minutes.
  • If moisture does not form on the outside of the glass, the air is too dry; you may need a humidifier. If water has condensed on the outside of glass, the level of relative humidity is high.
  • Will mold die if it dries out?

    Mold does not dry out and die but remains inactive for a while if moisture is not available. This means that it can still grow back and multiply when it is exposed to any sources of moisture. Professional mold remediation and moisture control help to keep mold at bay.
