Radon Mitigation Guarantee & Results

Great Systems,

DuPage Radon Contractors guarantees that the radon mitigation system will reduce your radon to below 4.0 pCi/L on the first try or any necessary adjustments are free. The system is also guaranteed to keep the radon low for five years and all parts have a five-year warranty.



Free, No Obligation Price for Your Building.

to Pass

DuPage Radon Contractors’ performance warranty guarantees that your system will lower radon to below 4.0 picocuries per liter of air, or any modifications to achieve that level will be free. We’ll even pay for the re-test if we fail the first attempt at lowering your radon test results.

to Perform

Our radon mitigation systems are effective for long-term radon reduction. Your radon level will stay low for at least five years with an operating system, or DuPage Radon Contractors will fix it for free.

Guaranteed Durability

Our Equipment Warranty covers all installed equipment for five years against workmanship or manufacturing defects. Fan replacement is provided as free parts and labor for the first year and free parts for the next four years. All other parts are covered as free parts and labor for five years.

Fine Print

Our fine print is easy to understand and reasonable. There are only four exceptions to our warranty:
1. Damage or alteration of the system done by others or acts of nature
2. Alterations or additions to the foundation structure
3. Obstructions to the suction path, such as a high water table, or damage to items in or below the floor
4. Sources of radon other than soil

Shopping around? Be sure to read the fine print of other companies’ warranties.

Can’t Always

We try our best, but a building can have challenges that make the performance warranty unable to be used.  In those rare situations, we will explain why and your options.


DuPage Radon Contractors’ promised goal is to lower radon levels below 4 pico curies per liter of air, but since all radon is unwanted, we try to produce radon levels as low as is reasonably possible. Each building and radon system yields different results, but here is a sampling of great results we’ve achieved in several homes.
