Radon mitigation quotes in Urbana
Urbana is the older half of the twin cities, with the county courthouse, a genuinely historic residential core, and a campus edge whose housing has been converted to rentals over generations.
Historic foundations plus long-unmeasured rental stock make Urbana the market where testing most often produces a surprise. Urbana owners hire independent, IEMA-licensed contractors.
Urbana and Champaign County
Urbana routes through our Champaign County territory alongside Champaign, Savoy, St. Joseph, and Ogden. Champaign County sits in EPA’s Zone 1 designation for central Illinois — a screening category for counties, never a forecast for a specific property.
If the result surfaced in a transaction
Urbana’s market includes university-employee sales, investor transactions near campus, and long-held family homes changing hands. Illinois disclosure duties attach identically to all of them: known radon information and the state pamphlet go to the buyer, and the fix is negotiated. Where no test has ever been run, there is nothing to disclose and your own measurement is the only real data.
Those duties are set in Illinois, not in Champaign 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 historic districts bring brick, block, and occasionally stone foundations with a century of additions — zone-by-zone design work rather than templated installs. Campus-adjacent conversions add partial basements and porch crawl spaces. East-side postwar and later construction is conventional, with poured or block basements and straightforward routing.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Champaign County soil and the same building era run through Champaign, St. Joseph and Savoy, which is why a reading in one of them is worth knowing about when you are interpreting yours. For the wider picture, radon across Champaign-Urbana sets out how results vary between communities here, and what a system costs in Champaign-Urbana covers the price drivers before you start collecting numbers.

Urbana questions, answered straight
Our 1900s house has a stone foundation and a dirt-floor section. Fixable?
Yes, with both conditions in the design. Exposed soil gets a sealed durable membrane with suction drawn beneath it; the masonry gets careful sealing of accessible openings, with suction points chosen after measuring how air moves under the slab. Confirm any quote names the dirt-floor area explicitly.
Is radon testing included in a home inspection?
No — it must be requested separately, and in Illinois a measurement performed for compensation must be done by an IEMA-OHS-licensed measurement professional. Buyers who assume it is bundled sometimes close without ever knowing the number. Ask for it during the inspection window.
Can a system be installed without a pipe on the front of a historic home?
Almost always. Contractors route on rear or side elevations, through the garage, or up an interior chase to the roof precisely because owners of older homes object to a visible run. Make routing part of the quote conversation — bidders who work historic property will have photos of discreet installs.
Where should the test device actually be placed?
On the lowest level you live in or reasonably could, at least 20 inches off the floor, several feet from exterior walls, and away from windows, vents, fireplaces, and anything blowing air. In an older Urbana house with a partial basement, that means a room you would furnish, not the corner beside the dryer. Kitchens, bathrooms, laundry rooms, and crawl spaces are excluded from valid placement because humidity and airflow there distort the result.
The kit says to keep the house closed. What does that actually require?
Windows and exterior doors stay shut apart from ordinary entry and exit, for 12 hours before a short-term test starts and for its full duration. Whole-house fans and window air conditioners stay off; the furnace and central air operate normally. In an Urbana spring or autumn, an open window is the single most common way a test gets invalidated — and in a transaction, a compromised measurement is one the other side can reasonably refuse.
