Radon FAQ for Essex, MA

What EPA Radon Zone is Essex in?
Essex and the 01929 zip code are in Essex County, which has an EPA assigned Radon Zone of 1. A zone of 1 predicts an average indoor radon screening level greater than 4 pCi/L.
Why are radon readings shown from areas near Essex?
No homeowner radon tests have been submitted for Essex yet. Because radon is driven by regional soil and bedrock geology, readings from the closest cities—and the Essex County average—are the best available indicator of local conditions until Essex 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 Essex?
Radon mitigation in Essex 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 Essex?
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.
