Radon Testing FAQ
Answers to frequently asked questions about the process of getting a radon test completed…
Radon is a naturally occurring radioactive gas that can build up indoors and increase the risk of lung cancer over time. You can’t see, smell, or taste it — the only way to know if your home has high levels is to test.
Our standard test takes 48 hours. After the testing device is picked up, the results are analyzed and we send you a report within 2–3 business days.
Yes — we need access to the inside of the house. After setup, you don’t need to be home during the test, but we’ll need access again when we return to pick up the testing device.
It is important that you maintain “closed-house” conditions for 12 hours before the test begins and during the full 48-hour test period. That means:
- Turn off fans that bring in outside air
- Keep windows closed
- Limit door use to normal entry/exit
We’ll send you a reminder before your appointment!
Yes, you can use your central heating and cooling system as usual. Just avoid systems that bring in outside air (like whole-house fans or HRVs) unless required for safety or health.
It’s very important that closed conditions are maintained and the test devices are left alone. If windows are opened or the monitor is moved, we may need to retest — and that could mean extra time and cost.
In many cases, yes — especially during real estate transactions. Testing helps buyers and sellers understand indoor air quality risks and meet lender or inspection requirements.
The cost of the radon testing, including travel time/mileage for two site visits, radon testing, analysis and interpretation is $320.
