Radon mitigation quotes in Aurora, Illinois

Aurora and Kane County

Aurora famously touches four counties — Kane at its core, DuPage and Will on the far east side, and Kendall to the southwest. That is trivia for most purposes and a genuine question when people fill out forms. Our answer is simple: all five Aurora ZIP codes (60502, 60503, 60504, 60505, 60506) route through our Kane territory, and because Illinois licenses radon professionals statewide through IEMA-OHS, the same contractors can work every corner of the city.

If the result surfaced in a transaction

Aurora’s transaction volume is high and varied — first-time purchases in the older wards, relocations into the far-east subdivisions, investor activity throughout. Illinois’ radon rules are the same across all of it: sellers disclose known radon information and hand over the state pamphlet, and the response to an elevated test is a negotiation, not a mandate. In the newer far-east neighborhoods, check for a builder-installed passive rough-in before pricing a full retrofit.

Those duties are set in Illinois, not in Kane County — Illinois radon disclosure rules has the statute and the agency behind it, and the Illinois home-sale playbook covers the part no statute decides: who pays.

The housing you’re mitigating

The city’s older stock brings stone and block foundations, additions, and the occasional Michigan basement — projects where contractor experience shows. The post-1990s stock on the far east side is mostly poured foundations with deep basements, often the most straightforward single-suction-point installs. Between them sit decades of ranches and split-levels where design is zone-by-zone. In short: Aurora quotes vary because Aurora houses vary, which is the argument for collecting more than one.

If that describes your house, the next question is usually what the work costs and whether you need it at all. Our guide to what mitigation costs across Suburban Chicagoland sets out the local price drivers, and how mitigation is actually done in Suburban Chicagoland covers the system types that suit these foundations. If you have not yet confirmed the reading, start with the difference between testing and mitigation — they are separate jobs, often done by separately credentialed people.

Two general guides sit behind those local pages: how much radon mitigation costs — commonly quoted ranges by home type and the six factors that move a quote — and how a mitigation system works, which explains the suction point, pipe, fan and manometer a Aurora quote should itemise.

Neighbouring towns share Kane’s geology and its housing eras more than they share a postcode, so a result two streets over in the next municipality is often more informative than one across the city. Radon across Kane County covers what the county line does and does not change — and it changes less than people expect, because Illinois licenses radon work statewide rather than county by county.

Who is licensed to do this work near Aurora

Illinois does not leave this to guesswork, and neither should you. IEMA-OHS licenses radon mitigation professionals for the whole state and publishes the active list itself — no account, no fee, no intermediary. It is the same list a search engine returns above the review sites, and it is the only list of Kane County mitigation supply that nobody paid to appear on.

• Search IEMA’s active licensee register — filter by licence type: mitigation and by service county or city to see who covers Aurora.
• IEMA’s printable mitigation licensee list for Kane County — the whole county on one page, useful if you want to work down it methodically.

Source: IEMA-OHS Radon Tracking System. Register locations last confirmed 2026-08-18. The register is live and the state’s; anything reprinted from it on this site carries the date it was last checked, and the register wins wherever the two disagree.

What a listing does and does not tell you

• It shows who currently holds an Illinois mitigation licence — not who is good, insured, available, or priced fairly.
• A licence covers a person or business, not a specific job. Confirm the licence you were quoted by is the one doing your work.
• Measurement and mitigation are separate Illinois licences. The list linked here is the mitigation list.
• Nobody on it has any relationship with Radon Connect. We do not place, rank, endorse, or receive anything from the businesses Illinois licenses.

So the register narrows the field; it does not pick for you. Ask every business you shortlist for its licence number and check it yourself — that habit is your protection, and how Illinois radon licensing works, and how to verify a number walks through it. When the quotes arrive, compare them on the eight lines that actually differ rather than the total at the bottom.

Prefer not to work the list yourself? Tell us the reading and the postcode and we will check coverage before asking for a single contact detail — start a request, and the confirmation tells you exactly what happened to it, including when the answer is that nobody covers you yet.

Deciding well in Aurora

• Identify your foundation era before reading quotes — historic, mid-century, or modern poured — because it predicts the design more than the ZIP does.
• In far-east Aurora homes built since the mid-2000s, look for a capped passive radon pipe before assuming a full system is needed.
• Verify each bidder’s IEMA-OHS license and ask what post-mitigation number their design targets.

A reading in the next town is often more informative than one across Aurora, because Kane’s housing eras and soil do not stop at a municipal line — radon in Naperville, radon in Oswego and radon in Batavia cover the neighbouring picture, and what a system costs across Suburban Chicagoland sets out the price drivers before you start collecting numbers.
