FAQ's in Shawnee

Here are some Frequently Asked Questions concerning radon mitigation Shawnee:

  • Are Radon levels Higher in Shawnee?

Shawnee is actually in a higher risk area of the country, so the potential for higher radon levels is greater than other portions of the country. As far as the KC metro area is concerned, it is not notably higher or lower than other KC based cities.

  • How do I know my system is running as it should?

Upon installation of the system, there is a visual indicator placed by the main suction point. We will demonstrate to you how to double check that the fan is operating properly and recommend that you check once a month.

  • How often will I have to pay attention to a mitigation system?

More often than not, you set it and forget it in a sense. That's kind of the point, peace of mind. We recommend you check the levels on the system once a month to ensure your fan is getting the right amount of suction. Other than that, it requires no real monitoring. That being said, sometimes fans start running loudly or burn out (usually 10 years later), and they require service. In short, you probably won't have to think about it 99.9% of the time.

  • Why does the exhaust point have to be so high?

In short, it has to be. There are codes and rules that govern where you can disperse radon from the system. It has to be above the roof line and a specific distance away from windows and openings to other buildings. If it is too low, it actually becomes detrimental as a system as it creates an environment where concentrated radon is actually forced back into the home, rendering the system more harmful than helpful.

  • Does the U-tube on the system indicate Radon Levels?

No. It is not an indicator of radon levels, but rather airflow through the system. It should be uneven, if it is even you are not getting proper airflow. Give us a call.
