Our System
Our ventilation system is engineered to increase air circulation and assist with exhausting air contaminants from the crawlspace. By increasing and purging the crawlspace with outside air, the potential for surface condensation, mold growth, wood rot, infestation of wood destroying organisms, accumulation of radon gas and other odors will be greatly reduced.
The system is specially designed to create a crossflow environment by moving or sweeping air across the crawlspace and exhausting the air from the subarea.
If you are familiar with the current building codes for subarea ventilation, you will notice that our design far exceeds these building codes.
We use two types of fans for this process, an isolation/intake fan and an exhaust fan.
Musty Odors
Musty odors are associated with damp soil (organic material) within an area that is poorly ventilated.
Other nuisance odors can be from previous sewage spills, sewer gases, animal excretions or even dead animals.
Radon Gases
According to the EPA radon is estimated to cause many thousands of deaths each year. The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths.
Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Generally radon will accumulate in the lowest area in the home (i.e. basement or crawlspace). Therefore, by utilizing our Crossflow system, radon accumulation will be greatly reduced.
Humidity/Moisture
Clay content in the soil can readily absorb moisture, but gives it up grudgingly keeping the crawlspace area moist. The moisture can be controlled by fixing leaks, seepage and increasing air circulation.
Vapor barrier is also a way to prevent moisture from entering the crawlspace. It does double duty by preventing the soil from absorbing moisture into the air and by blocking the release of ground moisture into the crawlspace.
