Split-levels and three-step ranches

The work here is often a split-level or a three-step ranch, and more than one level of those homes meets the ground. Bill looks under each part of the home. A finished lower level stays finished. Tell him which shape you have when you text.

Cook County, and a Will County corner

This is the largest Cook County set on the site. The 14 October 2026 read from the IEMA layer is 1,272 Cook County tests, a median of 2.5 pCi/L, and 27.5% at or above 4.0. Cook County in that read is 21.5%, so the village runs above the county. The Will County corner is a separate 47 tests, a median of 2.4 pCi/L, and 23.4% at or above 4.0. The rows do not list a system.

Do not blend the Cook list and the corner list into one figure. Neither list is the reading in your home. The same address can show up again, since a row here is a test. Steps for getting a number are on the radon testing in Orland Park page. Use that page when you still need a number. This page is the work after you have one.

If your radon is still 4.0 or higher after we put the system in, we come back and fix it for free, and we pay for the follow-up test.

The Will County corner changes the kit

Only the kit changes in the Will County corner. A Cook County address starts with the free mailed kit from the Cook County Department of Public Health. A corner address orders from the Will County Health Department. The charge for that kit is $8. The visit after a high result does not change. Check the county on the tax bill before you order, and say corner in the text if that is where the home sits.

Are Orland Hills, Palos Park, and Oak Forest covered on the Orland Park page?

Each of those villages has its own page. This page does not cover them.

We are selling an Orland Park home. Which test counts?

The one the contract ordered, from an Illinois-licensed measurement professional. Send that report along with the closing date so the work can follow the contract. A kit from either county is only for your own look at the home.
