How Often Should You Test for Radon in Rochester?

Radon is a silent threat that can build up in homes without any warning signs — it’s colorless, odorless, and tasteless. That’s why testing is the only reliable way to know whether your indoor air is safe. But once you’ve tested your home, a common question arises: how often should you test for radon in Rochester, New York?
​
Understanding when and how frequently to test is essential for protecting your family’s health and peace of mind.

Why Radon Testing Matters — Even After a Negative Result

Radon levels can change over time due to a variety of factors — from weather and seasonal changes to home renovations and changes in heating or ventilation systems. Even if your home tested below the EPA action level (4.0 pCi/L) once, that doesn’t guarantee it will stay that way indefinitely.
​
Because radon comes from the ground beneath your home, shifts in soil conditions or changes in the home’s foundation environment can lead to fluctuations — making regular testing essential.

Recommended Testing Frequency for Rochester Homes

Here is a simple guideline you can follow:
​
🧪 1. Test When You First Move In
Be sure to test your home for radon before moving in. This gives you a clear baseline and ensures that you’re not unknowingly exposing your family to unsafe radon levels.

📆 2. Test Every 2–5 Years
For most homes, experts recommend retesting at least every 2 to 5 years even if previous results were below the EPA action level. Radon levels can vary with:

• Seasonal temperature changes
• Changes in how your home is heated or ventilated
• Renovations or foundation work
• Changes to your HVAC system
  
  

Regular testing ensures these changes haven’t resulted in unsafe radon levels.

❄️ 3. Test After Major Home Renovations
If you’ve remodeled your basement, finished a crawl space, added new plumbing or made any changes that impact airflow or your foundation, it’s a good idea to retest. Construction can alter how radon enters and moves through your home.

🌦️ 4. Test After Significant Weather Events
Extreme weather — such as flooding, long periods of rain, or drought conditions — can shift soil and foundation conditions, sometimes increasing radon entry. In these cases, performing another test is a smart precaution.

Best Practices for Radon Testing in Rochester

✔️ Use Certified Test Devices
Make sure your test kit or service provider is certified and follows EPA guidelines for accuracy.
​
✔️ Consider a Long-Term Test
While short-term tests (2–7 days) are useful, long-term tests (90 days or more) provide a more accurate picture of average exposure throughout different conditions.

✔️ Test the Lowest Occupied Level
Radon levels tend to be higher in basements and ground-level rooms. Test in the lowest regularly used space to ensure safety where people spend time.

✔️ Retest After Mitigation
If you install a radon mitigation system, always test again to confirm that the system is effectively lowering radon levels.
