What's the Stack Effect and How Does it Impact Residents?

Thursday, August 26th, 2021 by Kristen Owenby

Mold doesn’t just lurk in crawlspaces; it has a direct impact on people living in a home. Due to the “stack effect,” air moves from below-grade spaces into the upper levels of the house—creating a vacuum in the crawlspace. Essentially, warm air passes upward and escapes through cracks, windows, vents, and other openings. As it does, air from the crawlspace rushes to take its place.

How does this impact residents?

If the crawlspace contains moisture, mold, and mildew, it could mean asthma, allergy, and respiratory problems. As the air in the crawlspace ascends, it carries mold, spores, dust, and other irritants with it.

Some homeowners think that crawlspace functionality is unimportant. However, crawlspace problems eventually impact the rest of the house. Mold irritates residents, rot eats away at wood, energy costs rise, and an entire house can sag due to crawlspace issues!
