Radon Testing in Manhattan, IL

Independent Radon Testing for Manhattan Homeowners Since 2002
Whether you're buying a newly built home, preparing to sell your current property, or simply want peace of mind, professional radon testing is one of the most important environmental tests you can schedule.
Radon is a naturally occurring radioactive gas that forms in the soil beneath our homes. Because it has no color, odor, or taste, elevated radon levels cannot be detected without professional testing.
Quality Environmental Testing (QET) has proudly provided independent radon testing throughout Manhattan and southwest Chicagoland since 2002. Using professionally calibrated continuous radon monitoring equipment, we deliver accurate, dependable results for homeowners, home buyers, sellers, and real estate professionals.
QET performs testing only. Our recommendations are unbiased and based solely on the conditions measured inside your home.
Why Manhattan Homes Should Be Tested
Manhattan has become one of the fastest-growing communities in Will County, attracting families with its small-town atmosphere, highly rated schools, and expanding residential neighborhoods. As the community continues to grow, new homes are being built alongside well-established neighborhoods, creating a diverse housing market.
Regardless of when your home was built, no property can be assumed to have a safe radon level.
Radon enters homes through openings where the foundation meets the ground, including:
-
Foundation cracks
-
Construction joints
-
Sump pits
-
Floor drains
-
Plumbing penetrations
-
Utility openings
-
Crawl spaces
Even two homes located in the same subdivision can have completely different radon levels due to differences in soil conditions, foundation construction, and airflow.
The only reliable way to know your home's radon level is through professional testing.

New Construction Should Still Be Tested
One of the most common questions we hear is:
"My home is brand new. Do I still need a radon test?"
The answer is yes.
Radon comes from the soil beneath the home—not from the age of the building.
Many newer homes are built tighter than older homes to improve energy efficiency. While this can reduce heating and cooling costs, it may also allow radon to accumulate indoors if it enters through the foundation.
Whether your Manhattan home was built five months ago or fifty years ago, testing remains the only way to determine the indoor radon level.

Our Professional Radon Testing Process
Quality Environmental Testing uses a professionally calibrated SunRADON 1028-XP Continuous Radon Monitor.
Every professional test includes:
-
Proper monitor placement
-
Minimum 48-hour testing period
-
Hourly radon measurements
-
Continuous monitoring throughout the test
-
Review of testing conditions
-
Electronic reporting
Rather than relying on a single reading, our continuous monitor records hourly changes throughout the testing period, providing a much clearer picture of radon conditions inside your home.

Preparing Your Home for Testing
To obtain accurate results, closed-building conditions should be maintained throughout the testing period.
Before and during testing:
-
Keep windows closed.
-
Keep exterior doors closed except for normal entry and exit.
-
Operate your heating and cooling systems normally.
-
Do not unplug or move the monitor.
-
Avoid unusual ventilation during the testing period.
We'll review the testing requirements before your appointment and answer any questions you may have.
Understanding Your Radon Results
Radon is measured in picocuries per liter (pCi/L).
The U.S. Environmental Protection Agency recommends taking corrective action when indoor radon levels measure 4.0 pCi/L or higher.
Some homeowners also choose to reduce levels between 2.0 and 4.0 pCi/L to further reduce long-term exposure.
Professional testing provides the information needed to make informed decisions about your property.
