Radon Mitigation

Radon Mitigation Services

If your tests indicate levels of radon that require attention, our team of engineers and technicians will design and install a custom radon mitigation system to effectively and safely move radon and other soil gasses out of your home. We also take additional measures to seal and close gaps in the foundation and drains that could let soil gasses into the home.

Radon Fans

Safe Shelter Environmental uses Radon Away fans. The highest quality fan in the industry.

  • Energy Efficient
  • Designed to allow water to filter through the exterior fan housing
  • Five-year warranty on performance
  • No air leakage


The fan is no longer in service if both columns are level equaling zero on the manometer. The manometer measures the inverse relationship between air flow and suction. You should be reviewing the systems manometer tubing on monthly or quarterly basis to verify that the fan is creating vacuum under the slab.

Check that the fan is operating:

Occasionally check the systems manometer tubing to confirm that the fan is creating a vacuum under the slab. The manometer is a pressure gauge measuring the inverse relationship between suction and air flow. It is not a measure of Radon concentration.
Check to make sure that there is power to the fan: switches are on, breakers are on. If both columns on the manometer are level, equaling zero, the fan is no longer working.

  • Check the clear hose at the top of the gauge (is it un-connected, crimped or clogged)

Retest your home every two years:

The EPA recommends that you retest your home every two years.


Radon mitigation systems are designed to effectively reduce in-home radon levels. One of the primary byproducts of a radon mitigation system is its ability to reduce moisture in your basement and/or overall humidity throughout your home.

From the time a radon mitigation system is installed to when most of our customers state they’ve noticed lower levels of humidity tends to be a few months. The biggest indicator is typically that the dehumidifier is running consistently less than normal. Additionally, the musty basement smell starts to recede.


Soil vapor gets drawn into your home as your home replaces the air that escapes from open windows and ventilation; think of your home like a giant vacuum that’s constantly pulling in air from below the foundation. Radon systems draw radon gas out of a home from underneath the home’s foundation (below the concrete slab) through a process called sub-slab depressurization, which creates a vacuum seal. This same process is continuously drawing out the moist/damp air from underneath your home’s foundation, which is how it is able to (eventually) dry out the basement. Of course, every home is different and the effects of a radon system reducing moisture as a byproduct of reducing radon gas can vary from home to home.
