What Is Causing These Problems in My Home?

While various factors can impact your crawl space and home, the biggest culprit has to do with the way your home was constructed. The practice of building homes with crawl spaces typically has called for having open vents to be code compliant. The idea was to allow better airflow under the house and air drying. However, experience shows this is an outdated practice that is more harmful to homes than it is useful. Open crawl space vents let outside air, water, and pests inside to cause a host of other problems that affect not only the crawl space but the rest of the house. This is because of the stack effect.
