Condesation in walk-in basement
I have a new construction shop built with a poured walk- in basement/garage beneath. The garage part has no outlet other than the garage door. After being closed up for several months, there was considerable condensation on the inside of the door and glass block windows.
I want to insulate the floor above and lay T&G strip flooring in the shop but I am concerned about the moisture below. I assume I need to vent the space below — any suggestions?
