Radon mitigation in Palos Park
Palos Park sits in suburban Cook County, and Cook County’s health department will send a radon test kit at no charge to anyone who asks through its online form. If you would rather see the level change through the seasons on a wooded lot, a reusable detector does that.
Text Bill the number and he’ll tell you what it means, free. If it comes back high, he’ll come out, walk the lot with you, pick the side for the pipe, and give you the price before anyone drills.
Wooded lots and a short exterior pipe
Palos Park homes are often on larger, wooded lots, and the pipe route has to respect that. When the run is outside, Bill picks the side with you, and a walkout basement or slope toward the preserves decides a lot of the design.
A walkout plus a crawl space is the layout that moves a Palos Park home into the upper price range. The wooded lot by itself does not add a line item.
Palos Park runs above Cook County
Palos Park’s recorded share is higher than its county’s. Our 14 October 2026 count from the IEMA layer shows 327 valid Cook County tests for Palos Park with no mitigation system on the record. One hundred of them, 30.6%, were at or above 4.0 pCi/L, and the median is 2.5.
Cook County in the same filter is 21.5% at or above 4.0 from 61,276 tests, with a median of 2.0. Palos Park’s median matches Orland Park’s Cook County median of 2.5, while its share is higher than Orland Park’s 27.5%.
One hundred of 327
A hundred Palos Park tests at or above 4.0 out of 327 is a little under one in three, and the county runs about one in five. Among the Cook County towns this site counts with the same filter, only Palos Park and Orland Park run above the county, and Palos Park runs highest. The other 227 tests came in under 4.0. Which group a given home on a given hillside falls into is not something the file can say.

Palos Park questions
Is 30.6% a reason to assume my Palos Park home is elevated?
It is a reason to test. 100 of 327 valid tests were at or above 4.0. The other 227 were under it. The median was 2.5. Only a test of your home sorts which group you are in.
Where does the Palos Park pipe end?
On an exterior run, the pipe ends about 12 inches past the gutter. Bill agrees the side with you before the install.
We are selling a Palos Park home. Which test counts?
The one in the contract, done by an Illinois-licensed measurement professional. A county kit or a detector is for your own information. Text Bill the result either way and he will explain the mitigation side.
Where can I get a radon test kit in Palos Park?
Cook County mails one free to any Palos Park address that asks through the county health department’s online form. The lab report comes back to you, and Bill reads it free.
Our Palos Park home has a walkout basement. Can you still fix it?
Yes. Walkouts and homes with more than one level touching the ground are a regular part of our work around Palos.
