What it looks at

A few honest signals, not a diagnosis.

This check does not measure your air directly. It helps you decide what is worth measuring, and why winter is the time to look.

How your rooms feel

Stuffy air by evening in winter is a common sign of low ventilation, and worth paying attention to.

Where you spend your time

Radon gathers on the lowest lived-in floor, so the rooms you use most shape your exposure.

Your testing history

Whether your home has ever been tested for radon is one of the clearest signals of what to do next.
