Introduction: Why Crawlspace Encapsulation Matters
Many New Hampshire homes have crawl spaces under the main floor. While these spaces are often out of sight, they can be a major source of moisture, mold, radon, and structural damage. In towns like Exeter, Kingston, Hampton, Dover, Stratham, Portsmouth, and Brentwood, older homes are especially vulnerable due to seasonal soil shifts, frost heaves, and high groundwater levels.
Crawlspace encapsulation is a professional method of sealing and protecting the crawl space, turning it into a controlled, dry environment that safeguards your home and health.
What Crawlspace Encapsulation Involves
Encapsulation is more than just laying plastic on the ground. Professional systems include:
- Vapor Barrier Installation
- Heavy-duty plastic or specialized membrane is installed across the crawlspace floor and walls.
- Sealed at seams, corners, and around support posts to prevent moisture from seeping into the home.
- Proper Ventilation and Conditioning
- Crawlspaces may be ventilated or conditioned depending on home design.
- Ensures airflow without introducing radon or excess humidity, protecting wood framing and ductwork.
- Drainage Management
- Any water entering the crawlspace is channeled into a drainage system with a high-end sump pump and battery backup.
- Prevents pooling water that can lead to mold, mildew, or foundation damage.
Benefits of Crawlspace Encapsulation
- Moisture Control: Prevents water from the soil from reaching the wood framing or floors above.
- Radon Mitigation: Works with or enhances radon mitigation systems by sealing entry points.
- Energy Efficiency: Reduces heating and cooling loss through unconditioned crawlspaces.
- Improved Indoor Air Quality: Reduces mold spores and allergens entering living spaces.
- Structural Protection: Prevents wood rot and damage from repeated frost heaves or shifting soil.
Why Professional Installation Is Critical
Encapsulation is not a DIY project. Incorrect installation can:
- Trap moisture instead of removing it, creating mold.
- Block radon mitigation systems or ventilation airflow.
- Fail to seal all seams and openings, allowing groundwater intrusion.
