Common Radon Mitigation Procedures

• Forces need to be redirected from the “stack effect.” The stack effect draws air from beneath your home and up into your living space. Depressurizing the soil beneath the structure allows the radon gas to be redirected.
• The radon gas is redirected. A hole is drilled into the slab, crawl space, or surrounding earth to create a suction point (sometimes, more than one suction point is needed). The radon gas is vented through a PVC pipe connected to the hole. The pipe can be installed through the house or outside. Some newer homes have radon control systems installed that run through the home.
• The radon gas is vented out, away from your home. The pipe is connected to a fan in the attic or to the top of the structure for proper ventilation.
• Radon entry points are sealed. To resist gas entry, cracks are sealed using a urethane caulking compound.
• A final system checklist is performed. The checklist makes sure the system adheres to US EPA Radon Mitigation Standards. Proper system labeling and proper fan installation are checked, as well as other key steps.
