Radon mitigation quotes in Wheaton
Wheaton is DuPage County’s seat and one of its older residential cores, which means its housing runs the full span — nineteenth-century homes near downtown, mid-century blocks around the Metra line, and newer construction toward the edges. Radon does not follow that pattern: two houses of different ages on the same street can test completely differently, because what matters is the soil gas under each foundation and how each house breathes.
If a test has come back elevated, we can introduce you to up to three independent, IEMA-licensed mitigation contractors who quote Wheaton homes. We are not the contractor; we make the introduction, and the quotes are free.
Wheaton and DuPage County
Wheaton lies entirely within DuPage County and anchors our DuPage territory alongside Naperville, Glen Ellyn, Lombard, and Downers Grove. Both Wheaton ZIP codes, 60187 and 60189, route through this territory.
If the result surfaced in a transaction
As the county seat and a heavily commuter-driven market, Wheaton sees steady resale activity, and radon tests most often enter the picture through a buyer’s inspection. Illinois requires sellers to pass along the state radon pamphlet and disclose known elevated results — it does not dictate the remedy. Sellers who test before listing keep control of the timeline; sellers who learn of a result mid-contract are negotiating against the inspection clock.

The housing you’re mitigating
Older Wheaton homes bring older foundations — block, brick, occasionally rubble — and additions that mix basement sections with crawl spaces. Those homes are entirely mitigatable; the design just gets more deliberate. Contractors may seal and membrane a crawl space, add a second suction point where an addition sits on its own slab, or work from a sump pit where drain tile exists. Newer Wheaton homes on poured foundations are usually the simpler single-point projects.
Deciding well in Wheaton
- On a borderline pair of results (say 3.8 then 4.6), look at the average and the test conditions rather than re-rolling the dice until a number you like appears.
- For a house with an addition or crawl space, insist that quotes state how each foundation section will be treated.
- EPA’s guidance is to act at 4 pCi/L and consider acting between 2 and 4 — the right threshold inside that band is a household decision, not a legal one.

Wheaton questions, answered straight
My two tests disagree — 3.8, then 4.6. Which number is real?
Both, probably. Radon levels swing with weather, season, and how the house was operated during the test, so EPA treats short-term tests as snapshots. When two results straddle the action level, the average (4.2 here) is the more honest summary, and it sits in the range where EPA recommends action. A long-term test or a continuous monitor can settle it if nothing is forcing a decision now.
Our house near downtown is over a century old. Is mitigation still practical?
Yes — older foundations are routine work for experienced contractors, though the design is more custom. Expect the quote to address sealing accessible openings, possibly a crawl-space membrane, and suction-point placement suited to the foundation type. Get more than one licensed opinion; approaches to old foundations genuinely differ.
Do I need to worry about radon if the bedrooms are all upstairs?
Test where the house is actually lived in. Radon concentrations are typically highest in the lowest occupied level, which is why tests are usually run in the basement or first floor. If a basement rec room, office, or gym gets regular use, that level’s number matters regardless of where anyone sleeps.
Who pulls the permit if a system is installed?
The contractor handles permitting where the municipality requires it — that is part of the job, not something a homeowner needs to research first. What you should verify yourself is the contractor’s IEMA-OHS mitigation license, which is required statewide.
