Crawl Space Radon Mitigation

Crawl spaces can allow soil gas to enter a building through exposed soil, foundation openings, drains, cracks, and other pathways. Testing and mitigation should account for the specific crawl-space construction.

Testing Crawl-Space Homes

The testing location and method should reflect how the crawl space and living areas are used and the purpose of the measurement.

Crawl-Space Mitigation

Possible approaches include active soil-depressurization systems and other building-specific methods. The correct design depends on whether the crawl space has exposed soil, a slab, a sealed floor, or other construction.

Existing Systems

If a crawl-space mitigation system already exists, service may include inspection, fan replacement, repairs, and post-repair testing.
