For the long-term stability of your home's foundation, it's vital to prevent moisture from accumulating in your crawl space. When you prevent dampness from gathering in your crawl space, you also prevent it from seeping through to the dirt which surrounds your home's foundation. Gutters aim water away from your home's foundation, but a moist crawl space under your home can cause trouble. Crawl space encapsulation helps prevent moisture retention and makes your foundation more stable for years.
