The Encapsulation Process Explained
Basement and crawl space encapsulation is a proactive solution to prevent moisture intrusion, which can damage your home’s foundation, belongings, and air quality. Heavy rain, poor drainage, or high humidity-common in Marin County and San Francisco-can seep into unprotected spaces, fostering mold, mildew, and structural issues.
Encapsulation involves:
- Inspection: Assess moisture levels, foundation condition, and HVAC integration using hygrometers and thermal imaging.
- Preparation: Remove debris, repair minor cracks, and install drainage systems like French drains or sump pumps.
- Vapor Barrier Installation: Apply 12-20 mil polyethylene sheeting to walls and floors, sealed with waterproof tape.
- Insulation: Add spray foam or rigid foam boards to walls or rim joists for thermal and moisture control.
- Dehumidification: Install certified dehumidifiers to maintain 40-60% humidity.
- Final Testing: Verify airtightness and drainage functionality with pressure tests.
This creates a watertight seal, reducing humidity to 40-60% (EPA-recommended levels) and preventing mold growth. In older homes with brick or stone foundations, encapsulation addresses cracks and mortar erosion, which worsen over time. By conditioning these spaces, encapsulation also improves HVAC efficiency, saving 10-15% on energy bills, per the Department of Energy.
