Do dehumidifiers bring moisture in through the concrete walls in a basement?
My husband and I are debating over if a dehumidifier will do harm/good in our basement. We are in Pittsburgh, PA and have a lot of rain and humidity. We just refinished our basement and have a full bathroom (with no ventilation) and part of the basement stands a laundry room with outside concrete walls as well as drywall. I smell a bit of a musty smell when going downstairs; however, there is no mold/mildew on the walls that can be seen. I want to use a dehumidifier but my husband believes that the dehumidifier is bringing in the air from outside through the concrete walls. There is also a sump pump present in the laundry room. Please advise to whom is correct.
