What is radon? ▼

Radon is a naturally occurring radioactive gas that can enter homes from the soil. It is invisible, odorless, and the only way to know your level is to test.

Are new or old homes more susceptible to radon? ▼

Any home can have radon — new, old, large, small, well‑sealed, or drafty. Radon depends on soil conditions, not home age.

Newer homes can sometimes trap radon more easily because they are built tighter for energy efficiency. Older homes may have more natural air leakage, but they can still have high levels depending on soil and foundation design.

The only way to know your home’s level is to test — age is not a reliable predictor.

Who can test my home for radon? ▼

You can test your home yourself using a free or low‑cost test kit, or you can hire a certified radon professional.

Do I need to act immediately if my level is high? ▼

Radon is a long‑term exposure risk, not an emergency like a gas leak or fire. You have time to understand your options, compare contractors, and make a thoughtful decision.

That said, once you’ve confirmed an elevated level, it’s reasonable to move toward mitigation within months rather than years.

Who can fix my home for radon? ▼

Certified radon mitigation professionals can install systems that reduce radon levels. However, not all certified mitigators think alike, and some don’t comply with national regulations.
