How Effective Are Radon Systems at Protecting Your Family?

7/9/2026

If you've recently tested your home for radon and the results came back high, you're probably asking one important question: Will a radon mitigation system really protect my family? The answer is yes. When properly designed and professionally installed, radon mitigation systems are highly effective at reducing indoor radon levels and helping create a healthier living environment.
​

Because radon is a naturally occurring radioactive gas, it can't be completely eliminated. However, a quality mitigation system can dramatically reduce the amount of radon entering your home and keep levels well below the EPA's recommended action level of 4.0 pCi/L.

How Do Radon Mitigation Systems Work?

Most homes with elevated radon levels use an active soil depressurization system. This system uses a specialized fan and PVC piping to draw radon gas from beneath your home's foundation before it enters your living spaces. The gas is then safely vented above the roofline, where it quickly disperses into the outdoor air.
​

The system runs continuously and quietly, providing around-the-clock protection with very little maintenance.

How Effective Are They?

Professional radon mitigation systems are extremely effective. In many homes, they reduce radon levels by 80% to 99%, although the exact reduction depends on the home's construction, foundation type, soil conditions, and the initial radon concentration.
​

A properly installed system not only lowers radon levels but also helps maintain those lower levels over time. That's why professional installation and follow-up testing are so important.

Why Professional Installation Makes a Difference

Every home is different. A mitigation system that works well in one home may not be the best solution for another. Experienced professionals evaluate your home's design, identify the best suction point, and install the appropriate fan and venting system to maximize performance.
​

After installation, post-mitigation testing confirms that the system is reducing radon levels as expected. This final step gives homeowners confidence that the system is working effectively.

Maintaining Your Radon System

Fortunately, radon mitigation systems require very little upkeep. Homeowners should periodically check the system's warning device or manometer to ensure it is operating properly and schedule radon testing every few years or after major home renovations.
​

​The mitigation fan is designed for continuous operation and typically lasts for many years before needing replacement.

Protect Your Family with a Reliable Solution

Since radon has no color, smell, or taste, testing is the only way to know if your home has elevated levels. If your test results indicate a problem, installing a mitigation system is one of the most effective steps you can take to reduce long-term exposure and improve your home's indoor air quality.

When it comes to installation, choosing an experienced contractor is just as important as choosing the system itself. RADON TESTING AND MITIGATION PNW provides professional radon testing and customized mitigation solutions designed for homes throughout the Portland area, ensuring every system is installed according to industry best practices. Their knowledgeable team also performs post-installation testing to verify the system is working properly, giving homeowners added confidence that their families are protected.

Final Thoughts

A professionally installed radon mitigation system is a proven solution for reducing indoor radon levels and lowering the health risks associated with long-term exposure. While no system can eliminate radon entirely, the right design, proper installation, and routine follow-up testing can provide reliable, long-lasting protection.
​

If your home has elevated radon levels, taking action now can help create a safer living environment for you and your family for years to come.

3. Inspect the Piping and Seals

Inspect the Piping and Seals
PVC pipes and seals carry radon gas out of your home safely. Regular inspection helps prevent leaks:
  • Look for cracks, loose joints, or disconnected pipes.
  • Ensure that all joints are properly sealed with primer and cement.
  • Check that vent pipes lead above roof level and away from windows or air intakes.

Even small leaks can reduce system effectiveness and increase indoor radon levels.

4. Monitor the System With a Manometer

Monitor the System With a Manometer
A manometer is a simple device that shows whether your system is functioning properly:
  • Check that the liquid in the U-tube indicates proper suction.

  • If the liquid level changes unexpectedly or shows no pressure, your system may need servicing.

Take readings regularly to ensure consistent performance.

5. Keep the Fan and Vent Area Clear

Radon fans are usually installed in basements, attics, or exterior areas. To maintain airflow:
  • Keep storage items away from the fan.
  • Ensure vent openings are not blocked by debris, leaves, or snow.
Avoid painting or covering any part of the vent or piping.
​

6. Test Radon Levels Regularly

Even a well-maintained system needs periodic radon testing:
  • Conduct a short-term radon test at least once a year.
  • After maintenance or system repairs, run a new test to ensure radon levels remain safe.
  • If levels rise above 4.0 pCi/L, contact a professional immediately.

Regular testing ensures your mitigation system is effectively protecting your family.

7. Know When to Call a Professional

While homeowners can perform basic inspections, some tasks require a certified radon mitigation professional:
