Radon Mitigation in Raleigh, NC & Surrounding Areas in the Triangle

As there is no known "safe" level of radon, any amount of radon can present some risk. Because your risk of developing lung cancer due to radon exposure is a function of time and the amount of exposure, your risk will be reduced by lowering the level of radon in your home through radon mitigation.

The technique used to reduce radon levels in your home is based on the foundation type, not on the radon level. There are two primary radon mitigation techniques used to reduce indoor radon levels: active soil depressurization and ventilation.

Methods of Radon Reduction & Mitigation

Active Soil Depressurization

The vast majority (approximately 90%) of radon that enters a home is from the underlying soil. Pressure differentials cause radon-laden soil gases to be drawn through small openings in the foundation. By applying a vacuum to the underlying soil that is greater in strength than the vacuum applied to the soil naturally by the house, a radon mitigation system can use active soil depressurization to collect the radon from the soil before it has a chance to enter the indoor living space.

Additional ventilation may be the most appropriate radon mitigation method, especially if there are other indoor air quality concerns that could benefit from improved ventilation. This technique brings additional fresh air into the home to pressurize the interior space and to dilute indoor radon levels.

Because the ventilation techniques involve the HVAC system, they are performed by a licensed HVAC contractor (not a radon mitigation company). Check with your preferred HVAC company if they're familiar with these techniques.
