What IEMA's radon test records show for Warrenville
IEMA publishes radon results reported by licensed measurement professionals. For test addresses in Warrenville, we counted 753 valid tests on homes without a mitigation system; 41% were at or above EPA's 4.0 pCi/L action level and 20% were at or above 8.0 pCi/L.
For comparison, 42% of tests were at or above 4.0 pCi/L across the 26 DuPage-area and nearby cities we pulled from the same data, so Warrenville is close to that average. These are mostly real-estate and homeowner-ordered tests, not a random sample, so they can't predict your house — neighbors on the same block can test very differently. The only way to know is to test your own home.
Housing in Warrenville and what it means for radon
About 13,553 people lived in Warrenville in the 2020 Census. The median home there was built around 1982, and the biggest share of its housing went up between 1970 and 1989 (19% before 1970, 47% from 1970–1989, 22% from 1990–2009, 13% since 2010). Roughly 43% of homes are detached single-family houses and 27% are townhouses or other attached single-family homes; about 75% of households own their home.
About 13% of Warrenville homes were built since 2010. Illinois' Radon Resistant Construction Act has required a passive radon pipe in new homes since June 1, 2013, so a newer house may already have a capped vent pipe. If it tests high, a licensed mitigator can often add a fan to that pipe instead of building a whole new system — usually the cheapest fix.
Nearly half of Warrenville's homes (47%) date from 1970–1989, which includes a lot of split-levels and raised ranches. Those often combine a basement slab with a crawlspace or slab-on-grade section, and a good system design accounts for both.
About 27% of Warrenville homes are townhouses or other attached units. If you live in one, check your HOA rules on exterior pipes and fans before you get quotes, and ask whether neighbors have already installed systems.
Next steps in Warrenville
- If you haven't, run a short-term test in the lowest lived-in level (EPA guidance). For a home sale, use a licensed measurement professional.
- If you're at or above 4 pCi/L, get a quote from an IEMA-licensed mitigator — Illinois requires the license for paid mitigation work.
- After installation, retest to confirm the level dropped.
