Our pipeline pulls from multiple sources to give you the most accurate risk assessment possible.
We look up your EPA radon zone, real test results from nearby homes, local climate, and your home's property records.
A few quick yes/no questions kids, pets, elderly residents, smokers so we can personalize the risk to your household.
A clear A–F grade, three risk breakdowns, personalized insights about your family, and a specific next step.
More Than a Letter Grade
Your report breaks down exactly where your risk comes from and what to do about it. It's designed to be clear enough to share with your family and specific enough to act on.
Your neighborhood, your home's structure, and your household are scored separately so you can see exactly where your risk comes from.
Personalized callouts about your specific household like why children's developing lungs face extra risk, or how pets spend more time near floor-level radon.
Not a vague "consider testing." Based on your grade: a one-time lab test, a continuous monitoring device, or a connection to a local radon professional.
If homes in your county have recorded radon levels over 10× the EPA action level, we'll tell you so you understand what the ground beneath you is capable of.
Three Questions. Three Scores.
Your grade looks at radon risk from three angles each weighted based on how much it impacts your home's overall safety.
Neighborhood Risk
"The risk that comes from where you live."Your geography is the biggest predictor. We check what experts predict should be there (EPA zones), what testing has actually found nearby (CDC data), and whether your climate keeps homes sealed up for months at a time (NOAA).
Home Structure Risk
"The risk that comes from how your home is built."Basements create more contact with soil gas. Older homes have more cracks and settling. Multi-story homes create a "vacuum effect" that pulls radon up from the ground. We check it all from your public property records.
Household Risk
"How radon uniquely impacts the people in your home."This is the part you help us build. Children breathe faster. Pets live near the floor. Smoking multiplies the danger. A few quick questions let us tailor your grade to the people who matter most.
