Colona and Henry County

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.

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.

Colona questions, answered straight
We are on a private well. Does radon apply to water?
It can. Radon dissolved in well water is released indoors during showers and washing — a separate exposure path with its own test and treatment. 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.
