- Eliminates Dirty and Potentially Poisonous Air
The EPA says that up to 60% of all air in the 1st floor of your home comes from the crawl space. Without sealing your crawl space, this “dirty” air is allowed to permeate the rest of the house because of a condition called ‘vapor transmission’.
- Controls Humidity Levels in the Entire House
When hot, humid air is allowed to enter your crawl space through the foundation vents. This same air is allowed through the rest of the house! The American Lung Association, American Medical Association, and the EPA recommend maintaining relative humidity levels in the 30% – 50% range.
- Creates a Dry and Clean Climate in Your Home
A dry and clean climate will no longer support mold growth. Excess moisture encourages mold growth on wood and any other organic material that is in the crawl space. Encapsulation will seal the area with non-organic material, reducing the surface areas where mold can grow.
- Elimination of Stale and Moldy Odors
Caused by crawl space moisture.
- Discourages Insect and Rodent Infestation
Insects and rodents prefer a damp environment to nest. Encapsulation will prevent moisture build up causing those damp conditions.
- Home Energy/Utility Savings
Some homes see a decrease of energy costs up to 15% per year from encapsulating their crawl space. The efficiency of your HVAC system is reduced because of open foundation vents found in most homes. Cold air in the winter and hot air in the summer travels into the home, thus making your HVAC system work harder and longer to keep your home warm or cool. The U.S. Department of Energy adds “If you properly insulate your crawl space – in addition to air sealing and controlling moisture, you will save on energy costs and increase your home’s comfort (A Consumer’s Guide to Energy Efficiency and Renewable Energy – Crawl Space Insulation).
- Preserves the Wood and therefore the Structural Integrity of Your House
The ground below most homes contains large amounts of moisture which enters an exposed crawl space as water vapor and, in some cases, may even become puddled water. When you combine that moisture with the dark and dank conditions of a crawlspace, you have a noxious, destructive environment where mold thrives and spreads at an alarming rate across any organic material. Aside from the fact that moist wood is like a dessert tray to termites, rot and decay set in and can eventually destroy the structural integrity of your home which could cost thousands upon thousands to repair.
