Moisture control is an important step in preventing damage from insects, mold and fungus in your home. The installation of a moisture barrier and proper foundation ventilation are important to controlling moisture, and preserving the wood foundation and subflooring of your home.
A moisture barrier in the crawlspace will cause soil moisture to condense on the underside of the barrier and return to the soil. This reduces condensation on floor joists, subflooring and other structural timbers that could lead to attack by wood-destroying insects.
Venting your crawlspace is another great way to control moisture in your home ultimately preventing an environment for mold, fungi, and insects that destroy wood framing. Foundation vents, are as their name implies, installed along the foundation of your home. These louvered metal vents allow air to circulate throughout a basement or crawl space and prevent dangerous moisture from building up beneath the house.
