Crawl Space Encapsulation – Seal Out Moisture, Mold, and Energy Loss
Your crawl space shouldn’t be damp, musty, or forgotten — it’s a critical part of your home’s health and comfort. With professional crawl space encapsulation, Force Basements seals your crawl space to block moisture/critters, improve air quality, reduce energy costs, and protect your foundation from long-term damage.
If you’ve noticed musty odors, high humidity, or cold floors above your crawl space, it’s time to consider full encapsulation.
How Force Basements Handles Crawl Space Encapsulation
We follow a comprehensive process to ensure your crawl space encapsulation system performs long-term and adds lasting value to your home.
1. Crawl Space Inspection
We assess your crawl space for standing water, mold, wood rot, pest activity, insulation quality, and ventilation issues.
2. Cleanout & Prep
We remove debris, old insulation, and damaged materials. We level the space and prepare it for sealing.
3. Vapor Barrier Installation
We install a thick, reinforced vapor barrier across the entire floor and up the walls, sealing it around piers and seams for complete coverage.
4. Seal Vents & Gaps
We block exterior vents and air leaks to stop outside air and moisture from entering the crawl space.
5. Install Dehumidifier or Drainage (if needed)
To control humidity long-term, we may add:
6. Optional Insulation & Structural Support
We finish the space with Crawl Space Insulation or Crawl Space Stabilizers if needed for energy efficiency or sagging floor correction.

FAQs About Crawl Space Encapsulation
What’s the difference between vapor barrier and encapsulation?
A vapor barrier covers only the floor. Encapsulation seals the entire crawl space — floor, walls, and vents — for full moisture protection.
Does encapsulation stop mold?
Yes — by controlling humidity, it prevents mold growth. Any existing mold should be removed first before sealing the space.
Is crawl space encapsulation worth it?
Absolutely. It protects your home’s structure, improves comfort and air quality, and often pays for itself in energy savings.
