Radon Testing in Roscoe, IL
Radon testing in Roscoe, Illinois covers homes of any age, since radon comes from the ground a house sits on rather than how old the building is. An estimated 2 out of 5 Winnebago County homes test above the EPA's action level.
Roscoe sits north of Machesney Park along the Rock River, mostly newer subdivisions and larger single-family homes. Newer construction here doesn't mean lower radon risk — it means the house is worth testing before assuming it's fine.

What we do in Roscoe
Radon testing
Radon testing measures the concentration of radon gas in a home, reported in picocuries per liter (pCi/L). The EPA recommends taking action at 4.0 pCi/L or higher and considering it between 2 and 4.0 pCi/L. Testing runs from a few days (short-term) to several months (long-term), placed in the lowest livable area of the home.
Buying or selling a home
Radon testing during a home sale is typically done as a short-term test during the inspection period, with results used to negotiate mitigation costs or move forward with the sale. Illinois does not legally require radon testing, but many lenders, buyers, and agents request it, and results must be disclosed if already known.
New construction
New construction radon testing checks a newly built home after it is fully enclosed, since radon comes from the ground the house sits on rather than the age of the structure. Many new homes include passive radon-resistant features during construction, and testing after move-in confirms whether those features are keeping levels below the EPA action level on their own or need an active fan added.
