Air draft from basement
Is it normal to have a draft of air coming from your basement to the
main floor? You can feel it easily coming from under the basement
door on the main floor level. The Basement windows and doors are
closed and when installed were sealed tight with foam. No draft is
getting in around them. Yet, the door on my main floor leading to the
basement has a fair amount of air draft coming in under the door. What
could be causing this?
