Radon Inspection Services in Plainfield, IL

Why Radon Is a Concern in Residential Homes

Radon is a naturally occurring radioactive gas that can seep into homes through cracks in foundations, basements, or crawlspaces. It’s odorless and invisible, yet prolonged exposure is the second leading cause of lung cancer. Because residential buildings can trap radon indoors, professional radon testing is essential to assess indoor air quality and detect dangerous levels before health risks develop.

Who Should Schedule a Radon Inspection and Why

Radon testing is essential for more homes than many people realize. Here’s who should consider scheduling a radon inspection and why:

  • Homebuyers – Test before closing to detect any hidden indoor air risks.

  • Homeowners – Regular testing ensures ongoing safety as radon levels can change.

  • Sellers – A test builds trust and avoids delays during real estate transactions.

  • New Construction Buyers – Even new homes can have elevated radon levels.

  • Basement Renovators – Disturbing soil or sealing spaces may increase radon buildup.

  • Health-Conscious Families – Prolonged radon exposure increases the risk of lung cancer.

What to Expect From a Professional Radon Test

Initial Site Evaluation

The inspector selects the lowest livable level of the home for monitor placement and checks for proper test conditions.

Closed-Home Conditions Requirement

To ensure accuracy, all doors and windows must remain closed (except for normal entry/exit) 12 hours before and during the test period.

Placement of Radon Monitor

A continuous radon monitor or approved test device is set in a central, undisturbed area to collect hourly air samples.

48-Hour Monitoring Period

The test runs for a minimum of 48 hours, recording fluctuating radon levels over time to provide an accurate average.

Data Collection and Analysis

After the testing period, data from the monitor is retrieved and reviewed for accuracy and consistency.

Detailed Report With Results

You receive a clear, easy-to-understand report showing the average radon level and whether it exceeds EPA-recommended thresholds.

Frequently Asked Questions

Do I need to prepare the home before a radon test?

Yes, windows and exterior doors should remain closed for at least 12 hours before and throughout the 48-hour testing period to ensure accurate results.

Where is the radon monitor placed during testing?

The device is placed in the lowest livable level of the home, ideally in a central area, away from drafts, high humidity, and direct sunlight.

How long does a professional radon test take?

Most tests run for 48 continuous hours to record hourly radon levels and calculate an accurate average.

Can I run HVAC or use appliances during the test?

Yes, you can use your HVAC system normally, but avoid whole-house fans, window fans, and fireplaces, as they may affect airflow and skew results.

What is considered a high radon level in a home?

A reading of 4.0 picocuries per liter (pCi/L) or higher is considered elevated by EPA standards and typically requires mitigation.

Overall a very professional and patient guy. We would absolutely hire him again."

He was very knowledgable and even pointed out issues that we did not notice. If you are looking for piece of mind when buying a home then Mike is your guy!!!"

Jonathan U.

"I'm really glad I chose Mike for the inspection of my new construction home. He is patient and pays great attention to detail in his work. He also takes the time to kindly explain and answer any questions I had, which helped me fully understand the process. My only regret is not having a pre-drywall inspection done. I strongly recommend not listening to the builder and instead getting an inspection done to save yourself from potential headaches."
