Radon mitigation quotes in Champaign
Champaign runs from the campus edge in 61820 west through decades of residential expansion in 61821 and 61822, which means its housing stock steps cleanly from pre-war homes near the university to modern subdivision construction on the far west side.
A radon result at or above 4 pCi/L is a solvable, priceable problem in any of them. We introduce Champaign homeowners to independent, IEMA-licensed mitigation contractors for free quotes; we never perform the work ourselves.
Champaign and Champaign County
Champaign anchors our Champaign County territory, which also routes Urbana, Savoy, Mahomet, Rantoul, St. Joseph, Tolono, and surrounding communities. Champaign County carries EPA’s Zone 1 designation. Illinois licenses radon professionals statewide through IEMA-OHS, so the license rather than the address is what you verify.
If the result surfaced in a transaction
The local market blends university-employee family moves with substantial investor activity near campus. Illinois requires sellers to disclose known radon information and provide the state pamphlet, leaving the remedy to negotiation. Buyers of campus-adjacent property should assume no test exists and order their own during the inspection window — radon is not part of a standard home inspection.
Deeper playbooks: radon in a home sale · what mitigation costs
The housing you’re mitigating
Campus-ring housing is largely pre-war on block and brick foundations, often subdivided into units, with partial basements and porch crawl spaces. Mid-century blocks bring ranches and split-levels. West-side construction from the 1990s onward is conventional poured-basement work with sump systems and attached garages that hide the pipe run entirely.

Champaign questions, answered straight
We are buying a campus-area house divided into units. How does testing work?
Test the ground-contact spaces — the garden level or first floor — because that is where radon concentrations are typically highest and where the number that matters lives. If mitigation is warranted, a licensed contractor usually designs one system for the building footprint rather than separate fixes per unit, then verifies with post-mitigation tests.
Our west-side house was built in 2009 and tested 5.1. How?
Radon comes from the soil beneath the slab, not from build quality, and tight modern envelopes hold entering soil gas rather than diluting it. The advantage newer homes often have is different: many carry a passive radon rough-in pipe, and activating one with a fan is a smaller project than a full retrofit. Check the attic before pricing anything.
What should a complete Champaign quote include?
Suction-point count and locations, the routing path, fan make and model with placement, sealing scope, a manometer, who handles electrical, warranty terms, the post-mitigation verification test, and the contractor’s IEMA-OHS license number. Missing items make a quote incomplete, not cheaper.
