What is radon mitigation, and how does it work?

Radon mitigation is the process of reducing and mitigating high levels of radon gas in a home or building to ensure a safe and healthy indoor environment. The goal of radon mitigation is to prevent radon from entering or accumulate within living spaces. The specific techniques employed for mitigation may vary depending on the structure and radon levels. However, common methods include sub-slab depressurization, which involves installing a vent pipe and fan system to draw radon gas from beneath the foundation and vent it safely outside. Other methods include sub-membrane depressurization for crawl spaces, sealing cracks and gaps in the foundation, and improving ventilation. Radon mitigation professionals conduct a thorough assessment to determine the most effective approach for each specific situation. Regular post-mitigation testing is recommended to verify that radon levels have been successfully reduced to acceptable levels.
