Encapsulation in home construction refers to sealing off areas like crawl spaces or attics with vapor barriers, insulation, and sometimes dehumidifiers to control moisture and improve energy efficiency. This process helps prevent issues like mold, wood rot, and pest infestations. In home inspections, encapsulation is checked for proper installation to ensure that the sealed space remains dry and well-ventilated, without trapping moisture or creating an environment conducive to mold growth. Proper encapsulation can significantly improve the home’s air quality and structural integrity.
