Radon mitigation across suburban Cook County
Our Cook County territory is deliberately scoped: the suburban ring, not Chicago itself. It clusters where our contractor coverage is strongest today — the northwest suburbs around Arlington Heights, Palatine, and Schaumburg, and the southwest corridor around Orland Park and Tinley Park — plus a band of neighboring communities between them.
Suburban Cook brings Chicagoland’s widest housing variety per square mile: postwar ranches, tri-levels, mid-rise condos, and vast townhome communities. We introduce owners of all of it to up to three independent, IEMA-licensed mitigation contractors for free quotes.
Radon in Cook County, without the mythology
Attached and multifamily housing gives suburban Cook its distinctive radon texture: ground-contact units are where numbers matter most, per-unit systems are the norm in townhomes, and associations govern exterior routing. None of that changes the fundamentals — EPA’s action recommendation at 4 pCi/L, the 2–4 consideration band, IEMA-OHS statewide licensing — it just changes who signs which approval.
Transactions here
From competitive northwest-suburb bidding wars to southwest-corridor family moves, Illinois’ rules are constant: radon is a disclosure item; fixes are negotiated. Two suburban-Cook patterns worth naming: buyers who waived inspections to win a house should simply test right after closing, and condo buyers should read declarations early, because association consent — not technology — is usually the pacing item on attached-housing mitigation.

Cook County questions
Why doesn’t your Cook coverage include Chicago?
Because we won’t pretend coverage we haven’t built. Our current contractor routing serves the suburban ring; Chicago ZIPs entered in the quote form get a direct “not yet supported” answer rather than a fake match, and those entries help us prioritize expansion. A platform built on honest routing has to start by being honest about its edges.
In a townhome, who owns the radon problem — me or the association?
Functionally both, in different lanes. Your unit’s air and the system serving your unit are typically owner responsibility; anything mounted on or penetrating common elements needs association approval. The workable sequence: test your unit, collect quotes, submit the contractor’s routing drawings for approval, install, retest. Contractors who work Cook’s townhome communities run that sequence constantly.
Are the postwar suburbs harder to mitigate than newer areas?
Not harder — just less uniform. A 1950s ranch without a sump takes a slab-core suction point; a tri-level takes zone-by-zone design; a rebuilt infill home may only need its passive pipe activated. Quotes vary accordingly, which is the argument for comparing more than one on anything older than the 1990s.
