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

Results

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.

Did you Know...?

  • 100% Success

    Sometimes, radon mitigation can be tricky. In some situations, it is challenging to get the radon levels low enough. However, over the years, we have always been able to get the radon below 4 pico curies per liter. We’ve even helped other mitigation companies on jobs they could not figure out.

  • 99.6% First Try

    Our first try success rate is exceptionally high. This reduces your time and any delays a second attempt may incur.

  • If Fail, Free Retest

    It happens, even to us, that we cannot get the radon test result levels low enough on the first mitigation attempt. If this happens, we have highly trained experts who will diagnose the issues and make the system adjustments. All at no charge. We will even pay for the retest.

  • Watch Out For “Lifetime” Guarantees

    Many companies’ lifetime warranties have so many exceptions that they don’t really offer much coverage. Sometimes, they only cover parts like PVC pipe that we know last a very long time. Be sure you understand what is and is not covered in competitors’ warranties.
