What Causes Condensation in Crawlspaces and Basements?

In many parts of the country during the spring, summer and fall months, warm, moist air enters the vented crawlspace from the outside and condenses on the cooler surfaces of the walls, floor and ductwork. These cooler surfaces are created within the crawlspace or basement by it being partially or entirely underground and shaded – much like a cave!

DP_condensation_arrows• If the Dew Point (DP) temperature is ABOVE the surface temperature,
condensation will occur.
• If the Dew Point (DP) temperature is BELOW the surface temperature,
there will be no condensation.

  • High Humidity
  • Pest Infestations
  • Poor Indoor Air Quality
  • Mold Growth
  • Musty Odors
  • Damage to Property

How do I prevent condensation?

Santa_Fe_Advance2-1Santa Fe offers a full line of dehumidifiers to help prevent condensation in these spaces. Several of the units feature dual exhaust to provide optimal airflow. This airflow helps prevent spot condensate, and in combination with the dehumidification, protects crawlspaces and basements.
