Humidity (Moisture) in Basements

Humidity (Moisture) in Basements

Humidity in basements is a very common problem.  The danger arises as a result of not being handled in the right manner.  Moisture problems can not only become annoying but pose a serious threat to one’s health.  That’s why it is of utmost importance to deal with any moisture problems before finishing a basement.

Knowing where the water is coming is the critical first step when trying to solve any humidity problems.  There are three sources of moisture to watch out for:

  • Water from rain or groundwater
  • Humid air that enters the basement externally and condenses on cooler surfaces
  • Moisture from internal sources such as humidifiers, unvented clothes dryer, bathrooms, and moisture from concrete after construction

 

Signs to Look For

  • Water leaking out of walls
  • Standing water on floors
  • Damp, humid air
  • Odor, mold, and mildew
  • Deterioration of carpet or wood
  • Dampness on concrete block walls

Typical Causes of Basement Humidity Problems

Inadequate Grading – Becomes a factor if the ground around a foundation is level or slopes toward the house. This can result in water to be directed into the basement.

Defective/Missing Gutters & Downspouts – Causes rainwater to be directed toward the perimeter of the foundation.

Improperly Designed Window WellsWindow wells are like a drain right next to the basement wall.  A  sign of poor design is if it directs water toward your home rather than away.

Ineffective Drain Tile & Sump Pit – These systems sometimes do not work for a variety of reasons:

  • Broken drain tiles
  • Clogging of the pipe with silt or debris
  • Broken connection to the sump.
  • The sump pit usually contains a pump designed to lift the water to the ground surface outside the foundation wall.  This pump can fail.

Structural cracks – Concrete and concrete block foundations usually develop some cracks.  Another cause can be soil settling.

 

Know the signs and ensure that basement humidity is not a threat to you or your family.
