Naperville sits across both DuPage and Will counties, and radon readings vary house to house even on the same street. EPA's guidance is the same everywhere: test, and if you're at or above 4 pCi/L, fix it. IEMA publishes test results by county and ZIP so you can see how common elevated readings are locally.

Naperville homes and radon
Naperville's newer subdivisions mostly have poured-concrete basements, which are usually simple to mitigate with one suction point. Older homes near downtown can have more foundation openings. Both get tested and fixed the same way: a licensed mitigator measures how air moves under the slab, installs a vent pipe and fan, and re-tests.
Testing during a home sale
Naperville's housing market moves fast and inspections often include a radon test. If yours came back high, request a quote with your closing date so the contractor can tell you whether they can install and re-test in time.
Check the license
Every mitigator we refer to must hold a current IEMA mitigation license. Look up any contractor on IEMA's county list before you sign.

Common questions
Is radon common in Naperville?
Radon varies home to home. IEMA publishes county and ZIP-level test data; the only way to know your home's level is to test it.
What number means I need a system?
EPA recommends mitigation at 4 pCi/L or higher and suggests considering it between 2 and 4 pCi/L.
My new house has a radon pipe already. Am I done?
Not necessarily. Passive pipes rely on natural airflow; test your home. If it's still high, a licensed contractor can often add a fan.
