So your buying a home and your questioning if you need a radon measurement with your home inspection or not.  Today I will help you with deciding  if a radon measurement is needed.  Iwill be using a home inspection I performed in Downers Grove, Illinois as my test subject.  I’ll really be speaking about the metro area in Chicago, Illinois but you can see maps that can help you in your area of the United States.

The first thing that always comes up is the cost of the radon measurement.  The standard price for a radon measurement is between $175.00 – $225.00, depending on where you are in the Chicago area and if you are getting a break on the price because you are getting a home inspection.  In Illinois a radon measurement must be done with a continuous radon measurement device.  We are not allowed to use charcoal canisters in real estate transactions.  These monitors are plugged into an electric outlet and they take a sample of the air every 15 minutes.  We generally put these monitors in finished basements or  rooms above crawl spaces.  Sometimes we may have up to 5 monitors for one home.  The Downers Grove home inspection had 2 monitors because there were two different types of foundations.

If your in Illinois and your wondering if you need to spend $175.00 on this measurement go to and see how your city or village rates with past radon measurements.  We measure radon by Pc/l.   This is a standard guideline that all can understand nationwide.  Radon can only be found by the measurements that we employ due to the fact that radon gas is colorless, tasteless and odorless.  This gas can cause cancer from its alpha and beta particles that implant themselves into your lung fibers.

So you want to remove the radon.  How much will it cost?  This depends on multiple factors and a radon mitigator can go over that with you and your family.  Mitigation systems can cost between $1200.00 – $2000.00 and more if there are multiple foundation areas that the mitigator will have to work with.  You can see other items that are related to radon measurement and mitigation at  This seemed to be very helpful for my clients of the home inspection in Downers Grove, Illinois.
