Mitigating your home for radon gas


What are my options for radon mitigation, and where can I see them in action?

We recommend working with a certified radon mitigation professional to find the most effective radon mitigation. The professional will take into consideration your home design and radon levels. Radon mitigation may include active soil depressurization, sealed sump pit covers, sealed floor cracks, sealed polyethlene membrane over exposed soil, or other forms of mitigation. Many of these mitigation options are on display at EcoSuperior's radon demonstration area, which is located at our office and open during normal operating hours, Monday-Friday 8:30-4:30.

Who can fix a home with high radon levels?
