You cannot see radon. You can test for it.

A home can look clean, well maintained and ready for closing while one indoor-air question remains completely out of sight. Radon is a naturally occurring radioactive gas. It has no color or odor, and neither a finished basement nor a careful look at foundation walls can confirm whether it is present indoors. The U.S. Environmental Protection Agency’s radon guidance is clear: testing is the way to learn about exposure in a home.

That makes radon worth treating calmly and separately from a home’s visible condition. The age of the house, a recent renovation, or the fact that a neighbor has tested does not replace a measurement at the property you are considering. For buyers, sellers and homeowners across Chicagoland, a radon test adds one useful piece of information to a much larger picture.

A general home inspection is a detailed visual evaluation of readily accessible components and systems. It can help you understand what an inspector can see at the property on the day of the visit. Radon is different: it cannot be identified by sight or smell, so it is not a conclusion a visual inspection can make.

Rojek Home Services offers radon testing as a separate service. Ask about it when arranging an inspection, or when you want information about a home you already own. Pairing the request with your inspection can keep your questions in one conversation while preserving a clear boundary between a visual inspection and a radon measurement.

What a test can—and cannot—say

A result provides information about the level measured during that test. It is not a promise about every past or future condition in the home, and it does not diagnose a foundation issue, identify every possible path into the house, or predict the performance of a future mitigation system. The value is practical: it replaces an invisible unknown with a documented result you can consider with current public-health guidance and your own advisers.

If you are buying, radon testing can be part of your overall due diligence alongside questions about the roof, mechanical systems, drainage and other visible conditions. If you are selling, it can help you understand an indoor-air question before a buyer raises it. If you already live in the home, it can give you a basis for deciding whether another conversation is appropriate. In each case, the result deserves context rather than a rushed conclusion.

Start by reviewing the report and the current guidance from the EPA and the Illinois radon program. If further evaluation or mitigation is appropriate, speak with a qualified professional about the options for your situation. Illinois licenses the people who provide radon measurement and mitigation services to the public and maintains a public license lookup. That is a useful place to verify a provider as you decide what comes next.

A sensible sequence

Keep the test record with your home documents. Discuss the result with the people involved in your transaction or home decision, and use the current EPA and Illinois resources when considering retesting or mitigation. A result should inform your choices; it should not be treated as a repair estimate, a health diagnosis or a guarantee about the home.

Rojek Home Services serves homeowners, buyers and sellers throughout Cook, DuPage, Will, Grundy and Kendall counties. A home in this region can differ from the one down the block in age, construction, improvements and how its lower level is used. Our approach is not to assume that a ZIP code, a basement layout or a previous owner’s account settles the question. It is to help you ask for the information that fits the property in front of you. See the communities we serve on our service areas page, or explore other targeted questions on our services page.

That same calm, fact-first approach is part of the company’s foundation. Founder Mark Rojek’s service as a firefighter and paramedic informs an inspection practice built around steady observation, direct explanation and appropriate next steps—not alarm or theatrics. Learn more about that background on About Rojek and meet the people who make up the Rojek team. Mark’s Certified Master Inspector credential belongs to Mark alone; it is not presented as a team-wide designation or as a substitute for a radon test.

Tell us whether you are purchasing, preparing to sell or already living in the home, along with the property address and any previous radon information you have. We can help you decide whether to request radon testing with your home inspection or as a separate conversation.
