The first step
is a measurement.
Radon has no smell or visible warning sign. A test measures its concentration in indoor air over a defined period, giving you information that a home's age, appearance or a neighbor's result cannot provide.
Radon Eraser helps homeowners, buyers, sellers and property managers plan testing around the property and the reason for the measurement. Tell us about your timeline, the space and any previous reports.
A useful answer
at the right moment.
- Your home has never been tested, or its radon level is unknown.
- You are buying or selling a property.
- You are planning a renovation or using a lower level as living space.
- A mitigation system has been installed or changed.
- You need updated information for a managed property.
A considered process.
A useful result.
Share the address, property type and inspection deadline before the appointment. Our team will confirm the scope, access arrangements and how the results will be delivered.
Commercial and multifamily properties may require more measurement locations and a different plan. Tell us how the building is used so the test can be scoped appropriately.
Plan the measurement.
Discuss the reason for testing, the occupied areas and any existing radon reduction system.
Place and protect the device.
The device is positioned for the agreed test. Follow the instructions, keep it in place and avoid changes that could affect the measurement.
Review the report.
We discuss the test-period result, relevant conditions and any recommended follow-up measurement or mitigation assessment.
Time changes
the picture.
Radon levels vary. Short-term and long-term measurements answer related questions over different time windows. The right test depends on your situation and the device being used.
A transaction deadline may call for a different measurement plan from a homeowner seeking a better understanding of annual exposure. Discuss the timing before booking.
A snapshot over a defined period.
Short-term tests run for 2 to 90 days, depending on the device. Many real estate tests last at least 48 hours. Follow the specific test instructions.
Good testing
needs good conditions.
Follow the instructions supplied for your particular measurement. Let every occupant know a test is taking place, and contact the team if those conditions cannot be maintained.
For a short-term test lasting 2–4 days, EPA guidance calls for closed-house conditions for at least 12 hours beforehand and throughout the test.
- Keep exterior windows and doors closed, except for normal entry and exit.
- Do not move, cover or disturb the testing device.
- Tell us about planned work, unusual conditions or changes during the test.
- Keep an existing mitigation system running during testing unless instructed otherwise by the testing professional.
- Make arrangements for access and share your reporting deadline.
A number with
context behind it.
| Radon concentration | How to think about it |
|---|---|
| Below 2 pCi/L | A lower result carries less risk, but no radon level is known to be risk-free. Retest as appropriate when the property or its use changes. |
| 2 to below 4 pCi/L | EPA recommends considering radon reduction. Discuss the test type and whether further measurement would help. |
| 4 pCi/L or higher | EPA recommends fixing the home. An initial short-term homeowner test may require follow-up to confirm the result; transaction protocols may differ. |
Use the full report and the appropriate testing protocol. A single instantaneous display is not a completed radon test.

Can I use a DIY test kit?
Yes. Follow the kit instructions carefully and use a qualified device or laboratory. Professional testing can be helpful when you need assistance with placement, conditions or a real estate transaction.
How soon will I have a result?
The measurement period and reporting time depend on the device and the agreed scope. Ask our team to confirm both when booking, especially if an inspection deadline is approaching.
Can a new home have elevated radon?
Yes. New and older homes can have elevated levels. A new home with radon-resistant construction features still needs testing to establish its indoor concentration.
Do I need a basement to have a radon problem?
No. Radon can enter homes with slabs or crawlspaces too. Testing is the way to establish the level in your property.
What if my first result is high?
Share the report promptly. The next step depends on the test type, result and purpose. Our team can discuss follow-up testing and a mitigation assessment.
Do I need to leave during the test?
Ordinary occupancy is generally compatible with a radon test. The key is following the required test conditions. Tell us about unusual occupancy or ventilation needs before the appointment.
