Radon Testing in Mokena, IL

Mokena IL

Accurate, Independent Radon Testing for Mokena Homeowners

If you own a home in Mokena, are buying one, or are preparing to sell, 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 often go completely unnoticed without professional testing.

Quality Environmental Testing Inc. has been providing independent radon testing throughout Mokena and the southwest Chicagoland area since 2002. We use professional continuous radon monitoring equipment to provide accurate results homeowners and real estate professionals can trust.

Unlike companies that also install mitigation systems, QET is an independent testing company. Our focus is providing unbiased, accurate testing so you can make informed decisions about your property.

Why Every Mokena Home Should Be Tested

Mokena is known for its established subdivisions, excellent schools, convenient commuter access, and family-friendly neighborhoods. The community offers a wide variety of homes, including ranches, two-story homes, custom residences, and newer developments.

While these homes may differ in age and construction, they all share one important fact:

No home is automatically protected from radon.

Radon enters from the ground beneath the home and can move inside through:

  • Foundation cracks

  • Expansion joints

  • Plumbing openings

  • Sump pits

  • Floor drains

  • Utility penetrations

  • Crawl spaces

Many homeowners assume that because their neighbor tested low, their own home will too. Unfortunately, radon doesn't work that way.

We've seen neighboring homes produce completely different test results because every home has its own foundation design, airflow patterns, and interaction with the soil beneath it.

The only way to know your home's radon level is to test your home.

Radon Testing During a Home Sale

Because Mokena has a very active real estate market, radon testing is commonly performed during home inspections.

Whether you're the buyer or seller, having reliable radon results helps avoid unnecessary delays and keeps everyone working from accurate information.

QET works with:

  • Home buyers

  • Home sellers

  • Real estate agents

  • Home inspectors

  • Attorneys

  • Property investors

Our electronic reports are easy to understand and are delivered promptly after testing is complete.

Many sellers also choose to test before listing their home so they understand the property's radon level before negotiations begin.

Our Professional Testing Process

Quality Environmental Testing uses a calibrated SunRADON 1028-XP continuous radon monitor that records hourly measurements throughout the testing period.

Our professional testing includes:

  • Proper monitor placement

  • Minimum 48-hour testing period

  • Hourly radon measurements

  • Tamper-resistant monitoring

  • Electronic reporting

  • Independent interpretation of results

Because our monitor collects hourly readings rather than a single measurement, it provides a much more complete picture of radon levels inside the home.

Preparing for a Radon Test

To ensure accurate results, closed-house conditions should be maintained throughout the testing period.

Before and during your test:

  • Keep windows closed

  • Keep exterior doors closed except for normal entry and exit

  • Leave heating and cooling systems operating normally

  • Do not move or unplug the monitor

  • Avoid unusual ventilation of the home

We'll explain everything before your appointment so you know exactly what to expect.

Understanding Your Radon Results

Radon is measured in picocuries per liter (pCi/L).

The EPA recommends taking action when radon levels reach 4.0 pCi/L or higher.

Even lower levels may be reduced if a homeowner chooses to further decrease long-term exposure.

If elevated radon is discovered, mitigation systems are often very effective at reducing indoor radon concentrations.

Testing simply provides the information needed to make an informed decision.

New Homes in Mokena Can Have Radon Too

A common misconception is that only older homes have radon problems.

In reality, radon comes from the soil—not from the age of the home.

Many newer homes are built with tighter construction methods that improve energy efficiency. While beneficial for heating and cooling, these homes may also retain radon more effectively if it enters through the foundation.

Whether your home was built in 1975 or 2025, testing remains the only way to know its radon level.
