Radon reduction techniques are used to stop radon entry and reduce indoor radon concentrations. IEMA recommends hiring a licensed mitigation professional to reduce your indoor radon concentrations, as you would hire a licensed plumber, pest control operator, asbestos contractor or other specialist.
Trained mitigators using specialized equipment can discover where radon is entering and advise homeowners on the best way to reduce radon concentrations. The most common technique used by radon reduction firms is called "subslab depressurization" (SSD) and does not require major renovations. Post-mitigation testing must be performed to determine the effectiveness of the mitigation system.
The cost of an active mitigation system is typically between $800 and $1,200 for installation, and the energy cost for running the fan will average around $100 per year.
