If a vapor barrier is not installed in crawl spaces during California’s seasonal changes, moisture from coastal humidity, seasonal rains, and groundwater can build up under the home. This often leads to mold and mildew growth, wood rot, and eventual structural damage. Damp crawl spaces also attract pests such as rodents and insects, while the rising moisture and spores negatively affect indoor air quality, worsening allergies and respiratory issues. Over time, the extra humidity forces HVAC systems to work harder, driving up energy bills. In addition, visible signs of moisture damage or mold can reduce property value and make a home harder to sell.
