Sealing the walls and floors of your crawl space can help prevent pollutants and soil gases, such as radon, from migrating into the house.
The EPA has stated that a typical home in the US has 0.5 to 1.5 Air Changes per Hour (ACH). The ACH is the rate in which outside air replaces indoor air by means of natural or mechanical ventilation. You may be asking where does the replacement air come from? The answer is your crawl space. Without a crawl space sealing service you run the risk of having contaminants rise with the warm air within your home.
This zone is problematic due to the “Stack Effect”, which is how a chimney works. It is the process of warm air rising in a home, potentially taking with it any contaminants that may be present.
Consequently, nature abhors a vacuum and the replacement air that is needed, most commonly enters at the lowest point of the home, the crawl space, continuing the contaminant cycle.
In addition to air quality there is potential for structural damage. If left unchecked, crawl space moisture can create a “Ripple Effect” systematically damaging your home due to wood rot and decay.
These few examples offer a potential breeding ground for moisture induced hazards such as mold, fungi and allergens. Radon gas can also find it's way into your house through the crawl space.
Next Step Environmental Services can asses the situation and provide proper treatment to your crawl space and moisture related issues with our crawl space sealing services which include moisture barriers, sub membrane depressurization and crawl space encapsulation. When combined with radon mitigation, crawl space encapsulation can be an effective radon prevention method.
Addressing a crawl space problem can make your home more energy efficient, improve indoor air quality and prevent structural damage to your home.
