For a week or so we have been wandering around down in the basement closing up and sealing off spots where there’s Cold Air Penetration. We’ve looked at the tub, basement drain, crevice along the top of the foundation, hole where the water line enters, and so on. So today let’s go upstairs to the first floor and see what is going on there.
Down in the basement we are fighting Cold Air Penetration. Up in the house we are fighting The Path that warm air takes as it tries to escape from your house.
