Air in your home flows from the bottom to the top. Based on the principal that warm air rises, as the air in your home is heated, it moves up though your house. Once the air makes it way up to the roof, it will normally be vented out though the soffits or ridge vent.
So where does all this air come from? Surprisingly the majority is not from windows and doors but instead from your crawl space! In older, more "leaky homes", air can fully pass through your house at a rate of two changes per hour.
Building professionals say that up to 50% of the air you breathe on the first floor of your home is air that came directly from your crawl space. Therefore, whatever is in your crawl space air is in your house and you are breathing it.

Moisture in your crawl space can lead to:
With a Foundation Systems encapsulation system you will not only stop crawl space leaks, and control moisture but also gain back a little peace of mind.
Keeping your budget in mind, FSM offers three different types of encapsulation and vapor barrier systems. Depending on what crawl space waterproofing outcome/benefits you are looking to achieve, we will have the solution for you.

Traditionally crawl spaces had vents that were supposed to relieve excess moisture from the air keeping the crawl space dry. Experts now know that this does not work, but instead allows much more variation in humidity creating much more moisture. Check out the graph below or learn more about venting in our resource center showing how important it is to close the vents and completely seal the crawl space.

Most crawl space issues are related to the ventilation system used in older construction methods. To learn more about the old technique, and why it should never be used please check out this informational article from Advanced Energy. And don't forget to have your crawl space insulated by Foundation Systems of Michigan.
