In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home's suction on the soil and by diluting the radon beneath the home.

Can radon always be mitigated?

There is not a radon clean-up solution because radon gas continuously seeps into homes from the soil below. You have to stop the flow. Mitigation systems become permanent components of the home and have to be running all of the time to keep radon out.

How do I get rid of radon in my home?

There's no single method that fits all radon removal system needs. Common techniques include: Sub-slab depressurization, where suction pipes are inserted through the floor or concrete slab into the concrete slab below the home. A radon vent fan then draws out the radon gas and releases it into the air outside.
