What is Crawl Space Encapsulation?
Crawl space encapsulation protects the area from humid air and ground moisture. Crawl spaces are notorious for moisture-related issues, particularly in areas with high humidity and frequent rainfall.
The concept is to seal the crawl space with a heavy-duty plastic vapor barrier placed on the floor. Foundation vents and walls are sealed. Finally, a crawl space dehumidifier is installed to regulate the moisture levels.
What are the Signs of Problems in the Crawl Space?
1. Signs of Crawl Space Issues
Some indications of problems are evident from inside your first floor living areas, such as:
- cold floor
- high humidity
- condensation around door frames
- musty smell
- uneven floors
- higher energy bills
2. Inspect the Crawl Space
Upon noticing several of these clues, you might want to examine the crawl space. Look for:
- mold
- rotted wood
- pest infestations
- cracks along walls
- damaged, hanging or fallen insulation
- condensation on equipment

Our Crawl Space Encapsulation Process
For encapsulation to work correctly, it must be installed properly. If any aspect of the encapsulation is done incorrectly, it won't achieve the goal of keeping your crawl space clean and dry. And failure to follow best practices could even create a hazard in your home!
- The crawl space must be sealable. All openings will be covered with a plastic vapor barrier, spray foam or foam board.
- The space must be cleaned and cleared. Inspect for mold and repair damage before encapsulation.
- Prepare for possible flooding with a water drainage system. It can be a simple gravel-filled French drain or a sump pump.
- Use the right product. Fiberglass insulation, for instance, works poorly in crawl spaces.
- Check that your gas-burning appliances and fireplace are NOT venting into the crawl space.
As you can see, the process has many steps, and each one requires specific tools and materials, as well as expertise. Trust the professionals at Croach® to update your home's foundation with crawl space encapsulation.
