Basement Humidity

When there are cracks or crevices in the base of your home, excess humidity and moisture will easily be able to get inside and cause problems. Humidity is a measure of the amount of moisture in the air. Whenever there are openings in the wall or floor, it is going to naturally seep inside. You may not notice that there's a problem at first as it often takes prolonged exposure before damages become obvious.

Warning Signs of a Problem

  • Home doesn't feel comfortable, even when the thermostat is set on the right temperature
  • Skin feels clammy or moist
  • Home smells musty (indication of mold growth)
  • Certain spots on the first floor of the home no longer feel level (indication of wood rot and deterioration)
  • Personal belongings in the basement are damaged
  • Wooden furniture appears to be rotting or warping


To take care of the problem, a dehumidifier can be installed to control the amount of moisture in the air. We install easy-to-use and simple-to-maintain units that will do their job without any prompting from you. This means that you won't need to worry about switching any levers or pushing any buttons to get them working. They will keep the relative humidity levels inside of the home at a safe and comfortable level.

What Causes Humidity and Dampness in Basements

Basement humidity and dampness are usually caused by two factors. The first factor is the basement itself. If you have a leaky basement whether from cracks in your basement walls and floors or from water seepage this can raise the realative level of humidity of your basement. The second factor is the temperature of your basement. Because basements are located beneath the soil line of your home, they will inherently have a lower temperature. This can lead to higher levels of humidity due to the inability of the air to hold the moisture. Both of these factors combined are the main causes of humidity and potentially mold growth in your basement.

Recommended Basement Humidity Levels

Studys have shown that as much as 50% of the air in a home comes from either the basement or crawl space. The air contained in your basement or crawl space is often higher in moisture content, or humidity, and carries with it many allergens and odors. Experts at the Enviromental Protection Agency and other sources recommend maintaining a relative basement or crawl space humidity level in the 30%-50% range. Anything above a 50% humidity level for an extended period of time can cause mold, mildew, and bacteria to grow in your basement.
