The basement level of our house (1/2 below grade) is currently just vinyl tile on concrete slab. It's cold during the winter, so we would like to carpet it. We do not get water penetration through the floor, but during the humid days of summer, there is frequently condensation on the floor (especially under furniture) where the very humid air contacts the cool floor.
What are our options for carpeting? Could we just lay down a carpet pad and carpet directly on the concrete / vinyl tile? Is it necessary to put down a sub-floor?
We were originally going to just do the pad and carpet, but I'm concerned about moisture / mold issues.
