Condensation in Basement under porch


Part of our basement goes under the front porch.
The front porch is a concreate slab. This is a new
home. We didn't see any condensation problems this
fall. We are seeing condensation problems this winter.
We are getting condensation on the ceiling
(porch concreate slab) of the basement that lies
under the front porch. We live in Kentucky.
The tempature has been 52-55 degrees in the basement
(un-heated) while the outside tempature has been
10-35 degrees. What can we do to prevent/control
the condensation probelem?

Condensation on concrete ceiling in basement

Condensation usually forms when warm, humid, moist air hits a cool surface. This is the same thing that happens on the outside of your glass of ice tea. Although your basement may appear dry, there is much humidity in the air. It takes several months for all the concrete and wood in a new home to completely cure. Running a dehumidifier will help reduce humidity, which should be kept somewhere around 50%. You can purchase a humidistat to keep an eye on the level. Running fans will help move the air and improve air circulation and help prevent mold/mildew. Watch for signs of mold/mildew. Disinfect affected areas with 50/50 bleach/water solution.
