      Radon FAQ for Caledonia, WI

      What EPA Radon Zone is Caledonia in?
      Caledonia and the 53108 zip code are in Racine County, which has an EPA assigned Radon Zone of 2. A zone of 2 predicts an average indoor radon screening level between 2 and 4 pCi/L.
      Why are radon readings shown from areas near Caledonia?
      No homeowner radon tests have been submitted for Caledonia yet. Because radon is driven by regional soil and bedrock geology, readings from the closest cities—and the Racine County average—are the best available indicator of local conditions until Caledonia homeowners submit their own results. The EPA still recommends testing every individual home, since levels can vary significantly from house to house.
      How much does radon mitigation cost in Caledonia?
      Radon mitigation in Caledonia typically costs between $800 and $2,000. Most homes with standard basements can be mitigated with a sub-slab depressurization system in the $1,000–$1,500 range. Factors that can increase cost include complex foundations, crawl spaces, or very high radon levels.
      Should I test for radon if I'm buying a home in Caledonia?
      Yes. Radon testing should be part of every home purchase. A short-term radon test is typically included as part of the home inspection process and costs $150–$250. If elevated levels are found, you can negotiate mitigation as part of the sale.
