1950 cinder block house with new double pane windows, concrete foundation, gas wall heaters, and two osculating attic vents on top of the roof. The landlord says to cover them up during winter months and uncover them during the summer the walls sweat, the windows sweat, carpet sweat, creating mold the house never really gets warm. What can I do to prevent all the moisture and mold. 916-904-2581 stuccoit1@yahoo.com
