How Do I Know If My Home Has Radon?

The short answer: you can't tell without testing. Radon is colorless, odorless, and tasteless — there is no sensory cue that gives it away, no matter how attentive you are.

Why Radon Is Different

This is genuinely different from most other home hazards. A gas leak has a distinct smell added specifically so you'll notice it. Mold often (though not always) comes with a musty odor or visible growth. Radon has none of that. A home can have significantly elevated radon levels and look, smell, and feel completely normal.

The Only Way to Know Is to Test

That's exactly why testing exists as a category — it's not optional information you might stumble onto, it's the only way the information exists at all.

Professional radon testing places certified electric monitors in your home for a defined period (typically 48 hours), which measure radon concentration continuously. The results are delivered as a clear, written report showing your actual levels compared to the EPA's recommended action threshold.

Common Misconceptions About Radon

A few things that do NOT reliably indicate radon, despite sometimes being mentioned: the age of your home, whether your basement feels "musty," or whether neighboring homes have tested clean. Radon levels can vary house to house based on very local soil conditions, foundation type, and even how air moves through a specific structure.

Get a Definitive Answer

If you've never tested, or it's been a while, testing is a simple, non-invasive way to get a definitive answer rather than relying on assumptions.
