Why Radon Testing Is Critical for Homes in Illinois (And Why You Shouldn’t Wait)

When it comes to protecting your home and your health, there’s one issue many homeowners still overlook—Radon gas.

Yet across Illinois and the greater Chicagoland area, elevated Radon levels are far more common than most people realize. The problem? You won’t see it, smell it, or notice it—until it’s too late.

That’s why professional Radon testing in Illinois has become one of the most important steps homeowners can take.

What Is Radon and Why Is It Dangerous?

Radon is a naturally occurring radioactive gas formed from the breakdown of uranium in soil. It moves through the ground and can enter homes through even the smallest openings.

Common entry points include:

• Foundation cracks

• Basement floors and walls

• Sump pump pits

• Utility penetrations

Once inside, Radon can accumulate to unsafe levels—especially in basements and lower living spaces.

According to the U.S. Environmental Protection Agency, Radon is the second leading cause of lung cancer in the United States, responsible for over 20,000 deaths each year. The key issue:Radon exposure happens silently over time. There are no immediate symptoms.

Why Radon Is a Serious Problem in Illinois

Illinois is classified as a high Radon zone, meaning a large percentage of homes test above the recommended action level.

In the Chicagoland area—including Lockport, Lemont, and surrounding suburbs—elevated Radon levels are extremely common.

Even more important:

• New homes are NOT immune

• Well-sealed homes can actually trap Radon more easily

• Neighboring homes can have completely different Radon levels

Translation:The only way to know your home’s Radon level is through testing.

Radon Testing: DIY vs. Professional Testing

Many homeowners consider using a DIY Radon test kit—but there’s a big difference between basic screening and accurate, reliable results.

DIY Radon Test Kits

• Lower upfront cost

• No real-time data

• Prone to user error

• Delayed lab results

Professional Radon Testing (Recommended)

• Continuous Radon monitoring

• Hour-by-hour data collection

• Controlled testing conditions

• Fast, accurate reporting

At Quality Environmental Testing (QET), we use professional continuous monitors (like the SunRADON system) to deliver precise 48-hour Radon testing with detailed reporting.

For real estate transactions or serious health concerns, professional Radon testing is the gold standard.

What Happens If Your Radon Levels Are High?

Finding out you have elevated Radon levels might sound alarming—but the good news is:

Radon problems are highly fixable.

A properly installed Radon mitigation system works by:

• Pulling Radon gas from beneath your home

• Venting it safely above the roofline

• Preventing buildup indoors

These systems are:

• Highly effective

• Long-lasting

• Able to significantly reduce Radon levels quickly

When Should You Test for Radon?

You should schedule Radon testing in Illinois if:

• You are buying or selling a home

• Your home has never been tested

• It’s been more than 2 years since your last test

• You’ve finished a basement

• You want peace of mind for your family

The reality: Every home should be tested at least once—and re-tested periodically.
