Crawl Space Concerns in Illinois
The Midwest combines multiple crawl space risks: radon gas seeping through soil, clay soils that move seasonally, and extreme weather events. A properly encapsulated crawl space with radon mitigation addresses the most serious health and structural risks in this region.
Local Tip — Illinois
Radon is the #2 cause of lung cancer in the US, and Midwest homes are in a high-radon zone. If you are encapsulating your crawl space, add a radon mitigation system at the same time — bundling saves $500–$1,000 vs. separate installations.
