My basement is partially finished. I have a wood floor that is about 3 feet off the dirt underneath. There is a french drain around the perimiter with a sump pump that seems to work overtime, but it keeps the sump clear and is working fine. Under the flooring there is a fresh air intake and an exaust fan that runs various times thru the day.
With all that my basement still smells very musty, will installing a vent with a fan to circulate air help?
