Radon crawl space cost varies widely depending on your location, the size of the crawl space, and the severity of the radon levels. For testing, expect around $150 to $300, while mitigation—like sealing cracks, installing a sub-slab depressurization system, or adding a vapor barrier—can run from $800 to $2,500 or more. It's one of those home improvements that feels expensive upfront but can be crucial for long-term health and peace of mind.
