Radon mitigation quotes in Moline
Moline climbs from the Mississippi up the bluffs, and its housing steps up with it: dense older neighborhoods near the river and the historic districts, mid-century expansion across the middle of the city, and newer subdivision growth on the south side toward the airport corridor.
A test at or above 4 pCi/L is a solvable, priceable problem anywhere in that range. Moline homeowners hire independent, IEMA-licensed mitigation contractors.
Moline and Rock Island County
Moline sits in Rock Island County, which EPA places in Zone 1 on its Map of Radon Zones. ZIP 61265 routes through our Rock Island County territory, which also covers Carbon Cliff, Port Byron, and Taylor Ridge. Illinois licenses radon professionals statewide through IEMA-OHS — the credential to verify for an Illinois-side home.
If the result surfaced in a transaction
Quad Cities transactions frequently involve buyers relocating across the river, which introduces a wrinkle worth naming: Illinois and Iowa handle radon disclosure differently, so paperwork that looked familiar in Bettendorf will not match here. On the Illinois side, sellers disclose known results and provide the state pamphlet, and any fix is negotiated.
Those duties are set in Illinois, not in Rock Island 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 older river-adjacent neighborhoods bring block, brick, and occasionally stone foundations with additions layered over decades. Bluff-side homes often have walkout or lookout basements — still in soil contact, still worth testing. South-side construction from the 1990s onward is conventional poured-basement work with sump systems and attached garages.
Radon results do not stop at a municipal boundary, and neither do the contractors quoting here: the same Rock Island County soil and the same building era run through East Moline, Rock Island and Silvis, 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.

Moline questions, answered straight
We are moving from the Iowa side. Do the rules change?
Yes, in the paperwork. Illinois requires sellers to provide the state radon pamphlet and disclose known elevated results under the Radon Awareness Act; Iowa handles radon disclosure under its own framework. Neither state requires mitigation. For an Illinois-side home, verify your contractor’s IEMA-OHS license specifically.
Our bluff house has a walkout basement. Does radon still apply?
Yes. A walkout still has a slab in soil contact and at least one below-grade wall, and radon enters through the same cracks, joints, and penetrations as in any basement. Walkouts are routine mitigation work — grade exposure on one side does not clear the slab.
What should a Moline quote include?
Suction-point count and locations, routing path, fan make and model with placement, sealing scope, a manometer, electrical responsibility, warranty terms, the post-mitigation verification test, and the contractor’s license number. Missing items make a quote incomplete rather than competitive.
Does a radon system change anything about our homeowners insurance?
Radon mitigation is not typically an insurance matter — it is not a covered peril, and a properly installed system is not a rated hazard. Where it does show up is at resale and appraisal, where a documented system with a verified post-mitigation test reads as a completed repair rather than an open condition. Treat the system as a maintenance asset with paperwork, and keep the electrical work to a licensed electrician so nothing about the install is questionable later.
Can radon come in through a floor drain?
An untrapped or dried-out floor drain is one of the classic entry routes, because it connects the room directly to the gravel and soil beneath the slab. It is also one of the cheapest things to fix — a trap primer, a one-way drain insert, or simply keeping water in the trap. A Moline contractor who inspects the drains before quoting is doing the diagnostic work properly; one who never looks at them is guessing at where the air is coming from.
