Short answerIndiana counties fall in EPA radon Zones 1 and 2, and EPA recommends testing every home regardless of zone. EPA recommends fixing a home at 4 picocuries per liter or higher. Many buyers add a radon test to the inspection. When levels are high, a mitigation system typically costs about $800 to $2,000 in Indiana.
What do inspectors check?
Radon is not part of a standard inspection unless added. A short term test runs for at least two days under closed house conditions.
What are the common findings?
- Results at or above 4 pCi/L.
- Existing systems with fans off or no recent test.
How serious is it?
Radon is a long term lung cancer risk. It is common and fixable.
What does it cost to fix?
| Item | Planning estimate | Source |
|---|---|---|
| Radon mitigation system | $800 to $2,000 | P |
Planning estimates, not bids. Local contractors may price differently.
When is a specialist needed?
Any result at or above 4 pCi/L. Use a nationally certified mitigation contractor and retest after installation.
If you are selling
Testing before listing lets you plan instead of react. If you have a system, keep it running and know your last result.
If you are buying
Add a radon test to your inspection. Ask for a system or a credit if the result is high.
