Vapor barrier between floors?

My basement gets damp in the summer, and starts to smell mildewy. In one room on the first floor, the smell creeps up through the floorboards. To fix this, I put up insulation and a 4mil plastic vapor barrier on the bottom of the joists over this one area. Does this present any problems with the moisture? Should I do this everywhere in the basement?

Your not fixing the problem! The problem is the humidity in the basement. Buy a good dehumidifier and set it to 50%.

what he said.
All you did was conjfine the problem to the basement, the mold is still there and will eventually get worse, and worse.

plus the purpose of a vapor barrier is to keep the moisture in your LIVING Space from getting into a place it could condense when cold,not the other way around.

sounds like you definitely need a humidifier, and possibly some good ventilation.
