Radon mitigation works by reducing radon levels within a building, typically through a system called active soil depressurization (ASD). This involves installing a vent pipe system and fan to pull radon from beneath the house and vent it to the outside, where it dissipates harmlessly into the air. The exact design of the system depends on the structure of the home, the level of radon, and other specific conditions. Professionals may seal foundation cracks and install a collection system in basement floors or crawlspaces to effectively capture radon gas before it enters the home. These systems do not require major changes to a home and are relatively low-maintenance once installed. Additionally, some homes may employ other mitigation techniques, such as increasing ventilation with piping or an air-to-air heat exchanger to lower indoor radon levels. Once a system is installed, follow-up testing is recommended to ensure it is working effectively. Regular maintenance checks help sustain its long-term performance, ensuring your home remains radon-safe.
