Radon mitigation quotes in Colona
Colona sits at the eastern edge of the Quad Cities metro where the Rock River meets the Hennepin Canal, a Henry County city that blends older river-town housing with newer growth drawn by metro access.
Colona homeowners hire independent, IEMA-licensed mitigation contractors — the same firms serving the larger Quad Cities market minutes west.
Colona and Henry County
Colona anchors our Henry County territory alongside Geneseo, with additional coverage in Cambridge and Hillsdale. Henry County sits east of Rock Island County within the western-Illinois region EPA designates Zone 1 on its Map of Radon Zones.
If the result surfaced in a transaction
Colona transactions draw metro buyers looking for value and space, and radon testing is standard Quad Cities inspection practice. Illinois requires disclosure of known radon information and the state pamphlet; the response is negotiated. Rural-edge properties are especially unlikely to have ever been tested.
Those duties are set in Illinois, not in Henry 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
Older river-adjacent homes bring block foundations with partial basements; newer construction is conventional poured-wall work with sump systems. Properties on the rural edges add private wells — a separate radon-in-water question — and occasionally farmhouse foundations combining several types under one roof.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Henry County soil and the same building era run through Geneseo, Silvis and East Moline, which is why a reading in one of them is worth knowing about when you are interpreting yours. For the wider picture, radon across Quad Cities (Illinois) sets out how results vary between communities here, and what a system costs in Quad Cities (Illinois) covers the price drivers before you start collecting numbers.

Colona questions, answered straight
Our water comes from a well. Is that a separate radon question?
It can. When radon travels in well water it is released into the air during showering and laundry — a second pathway that neither an air test nor a sub-slab system addresses. The soil-gas system that lowers your air number does not treat water. Address the air first, then test the water if you are on a well.
Is Henry County served as well as the metro?
Illinois licensing is statewide, so Quad Cities contractors quote Henry County as part of normal routes. We will not promise how many bidders respond or how fast — availability belongs to each independent contractor, and we would rather say that plainly than invent a number.
What if the retest still shows elevated levels?
Then the design needs adjustment, and that is what warranty terms are for. A licensed contractor may add a suction point, resize the fan, or extend sealing. This is exactly why the post-mitigation test belongs in the scope of work before final payment — it is the mechanism that keeps the system accountable.
We rent this property out. What does Illinois ask of landlords?
Illinois places disclosure duties on residential landlords: a landlord who knows of a radon hazard, or holds a result showing one, is required to disclose it to tenants, and a tenant may test at their own expense. The statute does not compel a landlord to test or install a system. That is the legal floor. Whether to go further is a business decision — a documented, mitigated Colona unit removes a recurring conversation and protects resale value.
Is a winter test worth running if summer read low?
It is worth doing. Western Illinois houses close up and run heat for months, and heating-season stack effect pulls harder on the soil beneath a Colona slab than a mild July does — so the same house frequently reads higher in January. A low summer number is real data about your best case, not the number to plan around. A second short-term test during the heating season, on the lowest lived-in level, completes the picture.
