Radon Mitigation in Hendersonville, Asheville, North Carolina

How Does It Work

Stack effect in the home draws air from beneath your home and up into your living space. Depressurizing the soil beneath the structure allows for the radon gas to be redirected with a vent system to the exterior of the home. A hole is drilled through the concrete slab to create a suction point (sometimes more than one suction point is needed). The PVC pipe is then installed through the house to above the roof, or through an exterior foundation wall of the home. This type of system is known as a sub-slab depressurization.

If your home has a crawl space, a piping system is installed on the crawl space floor in conjunction with a radon barrier, the radon gas is then vented through a PVC pipe that is connected to the crawl space system. The PVC pipe is installed through the house to above the roof, or through an exterior wall of the home. This type of system is known as sub-membrane depressurization.

The next step is installing the radon fan and extending the piping system to the exterior of the home. Proper sizing of the fan and piping system is important to effectively lower radon levels. Sizing of the system is determined by diagnostics testing of the slab or crawl space. If the system is routed to the attic, the fan will be installed in the attic or if through an exterior wall, the fan will be mounted on the exterior and a vent pipe will be extended to an approved location as required by system protocols.

Some newer homes have the radon piping system installed that runs through the home. The piping system is installed when the home is built. This type of system is known as a passive radon system. A passive system does not have a radon fan installed; it merely allows the radon gas to naturally vent to the exterior of the home.

Lastly, radon entry points are sealed. To resist gas entry, cracks are sealed using a urethane caulking compound. A final system checklist is then performed. The checklist makes sure the system adheres to US EPA Radon Mitigation Standards. Proper system labeling and proper fan installation is checked, as well as other key steps. Post mitigation testing is done within 30 days of the system installation to ensure the system is working effectively.
