Traditionally, homes are built with a ventilated crawlspace to allow “good” air in and “bad” air out. This is called cross ventilation – it seems like a good idea but after years of research, scientists have realized the theory of The Stack Effect. Warm and humid air enters your home at the crawlspace level and instead of moving out the other side of the crawlspace, it moves upwards the floor system and leaks into ventilated areas in the upper regions of the home. This is due to the fact that heat rises and also due to the pressure differences created by your mechanical heating and cooling system. When this air enters the crawlspace, it cools, causing the moisture it carries to condensate on wood, air ducts, and insulation. Let us seal your crawlspace to avoid all of these issues.
