Radon Testing in
Lemont IL

Professional Radon Testing for Lemont Homeowners and
Real Estate Transactions
Radon is one of those problems you cannot see, smell, or taste, but it can still be present inside a home. In Lemont, many homes have basements, crawl spaces, sump pits, foundation cracks, and lower-level living areas where radon can enter from the soil beneath the home.
At Quality Environmental Testing Inc., we provide professional radon testing in Lemont and the surrounding southwest suburbs. QET is a family-owned environmental testing company serving the area since 2002.
We do testing only, so our reports are independent and unbiased.
Why Lemont Homes Should Be Tested for Radon
1. Lemont has many homes with basements
Many homes throughout Lemont have full basements or finished lower levels where radon is most likely to accumulate. Since radon enters from the soil beneath a home, the lowest occupied level is often where the highest concentrations are found.
2. Lemont sits on limestone and glacial soils
Lemont is well known for its historic limestone quarries and sits in an area with limestone bedrock and glacial deposits. Geological conditions like these can influence how naturally occurring radon gas moves through the soil, although they cannot predict whether any individual home will have elevated levels. That's why every home should be tested rather than relying on neighborhood averages.
3. One home can test high while the neighbor tests low
This is one of the biggest misconceptions homeowners have. Two nearly identical homes on the same street can have very different radon levels because of differences in foundation construction, soil conditions, ventilation, and air pressure inside the home. The EPA specifically cautions against assuming a home's radon level based on the surrounding area.
4. New construction isn't automatically protected
Many homeowners believe newer homes don't have radon problems. In reality, newer homes can actually test higher because tighter construction improves energy efficiency while also reducing natural air exchange. Every home, regardless of age, should be tested.
5. Radon testing is common during Lemont real estate transactions
Professional radon testing is frequently requested during home sales throughout Lemont. Having a test completed early can help buyers and sellers avoid unexpected delays during closing.
Why Lemont Homeowners Choose QET
We've been testing homes throughout Lemont and the southwest suburbs since 2002. From historic homes near downtown Lemont to newer subdivisions, we've seen firsthand that radon levels can vary dramatically—even between neighboring homes.
