Why Independence Matters
One of the things that sets Quality Environmental Testing apart
is our independence.
Many environmental companies both identify problems and
sell the service to fix them.
At QET, we focus on testing.
Because we don't perform remediation, our recommendations
are based entirely on the results - not on selling additional services.
Our clients appreciate knowing the information they receive is
objective, professional, and unbiased.

Why We Perform Testing Only
Illinois law prohibits the same company from both performing the initial radon test and installing a mitigation system at the same property. This requirement helps protect homeowners by reducing potential conflicts of interest.
Because Quality Environmental Testing performs testing only—not mitigation—our recommendations are always independent, objective, and focused solely on providing accurate results.
