Radon mitigation in Tinley Park

Our shop is in Tinley Park, and the county line runs through the village, so the cheap test depends on your tax bill. Cook County side: ask for the free mail-in kit. Will County side: pick up the $8 kit at the Joliet, Bolingbrook, or Monee health department office. Either side can set out a detector you can reuse instead.

Text Bill the number and he’ll tell you what it means, free. If it is high, he drives over from the shop, looks at the foundation, explains what the home needs, and gives you the price. New systems usually get scheduled within a week or two.

Two counties, one village

The line between Cook County and Will County runs through Tinley Park. Your tax bill says which side you are on, and the county decides the kit. The mitigation visit is the same on both sides.

Brookside Glen and similar Tinley Park addresses with Lincoln-Way schools have finished lower levels and lookout walls, and the foundation layout drives the design.

The pipe on a Tinley Park exterior

A finished basement, a sump, a crawl space, and a split-level all change the route. When the pipe runs outside, it ends about 12 inches past the gutter, and Bill walks the route with you before the work is scheduled.

Tinley Park in the IEMA file, county by county

Because the village straddles the line, the IEMA-OHS licensed-test layer splits Tinley Park in two. Our 14 October 2026 count of valid tests with no mitigation system on the record gives the Cook County side 786 tests, a median of 1.9 pCi/L, and 18.4% at or above 4.0. The Will County side is smaller: 105 tests, a median of 2.1, and 22.9% at or above 4.0.

Both sides sit under their own county. Cook County as a whole is 21.5% at or above 4.0 with a median of 2.0; Will County is 44.9% with a median of 3.5. The Will side of Tinley Park is about half the county share, and the Cook side is a few points under its county. The state radon page still says every home should be tested, including the one next door to a low result.

Home base, read plainly

Those 891 Tinley Park tests are the ones we see most often, because they are our own streets. Fewer than one in five came back at or above 4.0, which is the lowest share among the Will County towns on this site and in line with the Cook County towns around it. That still leaves well over a hundred Tinley Park homes in the file at the EPA action level, and none of them knew until a kit went out.

Tinley Park questions

Do Cook County and Will County Tinley Park homes use the same test kit?

No. A Cook County address can request the free mailed kit from the Cook County Department of Public Health. A Will County address uses the $8 kit from the Will County Health Department. Text Bill the result either way.

Where does the outside pipe stop?

On an exterior run, the vent pipe ends about 12 inches past the gutter. Bill walks the route with you before the work is scheduled.

Is a Tinley Park home sale tested the same way?

No. A contract test comes from an Illinois-licensed measurement professional, not a county kit. Ask your agent or attorney what the contract requires, then call Bill about the mitigation side.

Are you actually in Tinley Park?

Yes. American Radon Systems is family-owned and based in Tinley Park, and Bill has done radon work here since 2011. Most of the village is a few minutes from the shop.
