Frequently Asked Questions

The mitigator's warranty guarantees the radon level is less than 4.0 pCi/L. Why do I need a post-mitigation test?

The mitigation contractor's warranty guarantees that the system will reduce radon levels to less than 4.0 pCi/L, when tested in accordance with the Measurement Protocol, 32 Illinois Administrative Code 422.130. Diagnostic testing, conducted by the mitigator may suggest that the radon level has been successfully lowered, but the only way to know that the system achieves the sought reduction is to perform a post¬mitigation test in accordance with regulations. Relying on diagnostic testing that is neither standardized nor in accordance with regulatory requirements undermines the mitigation process. Further, it fails to document system performance and to activate your warranty in the event of system failure.

Can the same person test and mitigate a home?

Only if that person is the resident. If the person provides measurement or mitigation services, the answer is "No." 32 Illinois Administrative Code 422 prohibits licensed measurement and mitigation at the same address by the same practitioner.

Why isn't radon testing required by law, if it's such a problem?

States take varying approaches to protecting their citizens against the adverse health effects of radon exposure. A few states have passed laws that require testing in schools, day cares, or the installation of passive radon reduction systems, at least, in areas where there is high potential for elevated radon levels. In 1997, the Illinois General Assembly, in order to safeguard the health, property, and public welfare of its citizens, declared that persons engaged in the business of detecting and reducing the presence of radon and radon progeny in the indoor atmosphere must be licensed. Also, the Illinois Real Property Disclosure Law requires that knowledge of elevated radon levels be disclosed to potential buyers, along with many other items of consumer interest. As with many other issues, individuals, in their own interest, must learn about radon risks and take action to reduce or (/iema/) manage them.

What Our Clients Say...

Nancy was outstanding to work with. Having zero background knowledge on radon issues in a home, I was very comfortable trusting Nancy's expertise. Her knowledge and professionalism were top-notch and I would highly recommend her.

- Marlo - Vernon Hills, IL

I had just learned a little about the health risks of radon and wanted to find out the levels of our house. Nancy and Kellie from NE Illinois Radon Testing performed the test at our house and were both very professional.  They willingly explained and answered my questions regarding the test, radon health risks as well as what to do after a potentially "bad" test-result.  Luckily for us, we ended up getting good news and it's a nice "peace of mind". I recommend getting your house radon tested!

Tina O. - Mundelein, IL

If you have never owned a home before, or even if you have and are buying a different one, there is a an element of safety that you cannot afford to pass up in the process that we just learned about. We were alerted by our real estate agent on the dangers of Radon and how important it was to test for it. Upon learning how important it was, we decided to contact Nancy to have our testing done immediately after our bid was accepted on the home. She made the process as quick, easy and painless as a stroll in the park. Within days we had the confirmation that our new home was safe and ready for our growing family to move in and live happily ever after. I highly recommend her services and I will certainly be referring anyone who asks about it to give her a call. You won't be disappointed...and you will be safe!
