Crawl space foundation vents have long been a standard in home construction, often misunderstood by homeowners. Traditionally, these vents were meant to allow air circulation beneath your home, preventing moisture buildup that could lead to mold, mildew, or wood rot. However, as building science has evolved, so has our understanding of crawl space health.

Why Foundation Vents Are Becoming a Thing of the Past

In areas with high humidity and seasonal changes, the approach to crawl space ventilation is shifting. Modern building codes are moving away from foundation vents, as they often do more harm than good—letting in humid air that condenses and contributes to moisture problems rather than keeping the space dry.

Fortunately, NEPA Crawl Space offers a modern solution. Our crawl space vent sealing services use high-quality foam board and spray foam to prevent excess moisture and promote a dry, healthy crawl space environment. We also provide advanced crawl space dehumidifiers to further improve air quality and energy efficiency. Contact us today to learn more!
