Your radon test came back high. Here’s the calm version of what happens next.
An elevated result is a solvable, priceable problem — not an emergency. Radon Connect explains what your number means, then introduces you to up to three independent, Illinois-licensed mitigation contractors who quote your home for free. We never do the work ourselves, so our only job is telling it to you straight.

What your number actually means
Radon is measured in picocuries per liter (pCi/L). EPA recommends taking action at 4 pCi/L or higher and suggests considering action between 2 and 4. Those are health-based recommendations — useful, national, and worth taking seriously.

When mitigation makes sense
| Your situation | The straight answer |
|---|---|
| Tested at 4 pCi/L or higher | EPA recommends acting. Mitigation is the established fix — get quotes, compare designs, hire a licensed contractor, verify with a retest. |
| Between 2 and 4, inside a home sale | Frequently negotiated anyway, because a written quote is cheaper than an argument. Whether to act in this band is a judgment call, and it’s genuinely yours. |
| Between 2 and 4, staying put | Consider a long-term test for a better average. Households that use the basement heavily often act in this band; others watch and retest. |
| Below 2, or not tested yet | No result here calls for mitigation. Test (or retest in a couple of years) before spending money — and be suspicious of anyone who says otherwise. |
What mitigation involves
The standard fix is active sub-slab depressurization: a licensed contractor cores a small opening in the slab, runs a sealed pipe to above the roofline, and a continuously running fan pulls soil gas out from under the house before it can enter. Installation is typically a single working day, finished with a manometer you can glance at and a follow-up test that proves the number dropped.
What it tends to cost
In this region, straightforward single-point systems are commonly quoted in the low four figures, with multi-zone foundations, long routing runs, and older structures quoting higher — and activating a builder-installed passive pipe often quoting lower. Exact numbers are the contractors’ to give; that’s why quotes are the product here.
On a real-estate clock?
Most Chicagoland radon results surface during a purchase inspection, which means the decision usually has a contractual deadline measured in days. The sequence that keeps deals together: confirm the result, get a written mitigation quote, and negotiate a fix or a credit from a real number instead of a feared one. Illinois requires sellers to disclose known radon information — the remedy itself is negotiated, not imposed.
How Radon Connect works
- You tell us the situation. Test result, timeline, property basics, and the ZIP — which we resolve against our coverage instantly and honestly.
- We introduce up to three licensed contractors. Independent businesses, each holding the IEMA-OHS license Illinois requires. They contact you directly with their own quotes.
- You compare and choose — or don’t. No fees, no obligation, and no pressure from us in either direction: we have no stake in which quote wins.
Radon Connect does not employ radon technicians, does not sell or install mitigation equipment, and has no financial stake in whether any individual home is mitigated. Our role ends when we introduce you to independent licensed contractors; every estimate, contract, and warranty is between you and the contractor you choose.
Where we work today
Coverage is deliberate and ZIP-exact: six county territories across suburban Chicagoland. If your ZIP isn’t supported, the quote form says so plainly instead of pretending.
24 published city guides across 6 county territories. Additional markets — Denver, Minneapolis–St. Paul, Pittsburgh, Indianapolis, Columbus — are planned and will launch with the same honest-coverage rules.
Quick answers
Is this service really free?
For homeowners, yes — completely. We may be compensated by the independent contractors we refer requests to, and we disclose that everywhere rather than burying it. You pay nothing to us, ever, and quotes carry no obligation.
Do you install the systems?
No — and that is the point of the model. Radon mitigation in Illinois is performed by IEMA-OHS-licensed contractors. We introduce you to independent licensed businesses and step aside; every quote, contract, and warranty is directly between you and the contractor you choose.
A contractor quoted me without a site visit. Is that normal?
Common and legitimate for straightforward homes — many systems are quoted from the test report, photos, and foundation details, with the design confirmed on installation day. Complex foundations (older homes, multiple zones) more often justify a walkthrough. Either way, insist the quote itemize suction points, routing, fan, warranty, and the verification retest.
What if my ZIP isn’t covered?
The form will tell you immediately and honestly. We record unsupported requests only as expansion interest — never routed anywhere — and we point you to IEMA-OHS’s statewide listings of licensed professionals so you still have a real path forward.
