The average radon level in Minnesota is more than three times higher than the national radon level. This means that a radon mitigation installation is essential to protecting you and your family from the effects of this invisible gas. 

Symptoms of radon exposure often include and can lead to:

  • Persistent cough
  • Chest pain
  • Wheezing
  • Lung cancer

The radon mitigation process involves sealing openings to prevent the gas from entering your home and installing a ventilation system that helps remove radon from the air.

Additionally, our sub-slab depressurization system for radon mitigation can help to eliminate mold, mildew, radon and other soil gasses from your home. Whether you’re in need of radon mitigation or sub-slab depressurization, our system does both. 


Standard Water Control has installed radon mitigation systems/sub-slab depressurization systems in homes across Minneapolis, Saint Paul, and Western Wisconsin.

We have years of experience designing, configuring, and installing radon systems. We fully understand radon codes and are certified to help reduce radon levels in your home.


Standard Water Control is a National Radon Proficiency Program Certified radon mitigation company. Read our About Us page to learn about the requirements of the NRPP certification.


Whether you’re buying or selling a home or you’re looking for more information, it’s important to be well-informed on radon control/mitigation and sub-slab depressurization. Learn more from the EPA or contact Standard Water with any questions you may have!

What is Radon Mitigation?

Radon mitigation is the process of reducing radon gas in buildings or homes. Radon mitigation systems are extremely effective—in fact, they can reduce radon levels in homes and buildings up to 99%.

What Causes Radon?

Radon is a gas that forms naturally when uranium, radium, and thorium break down in soil, groundwater, and rocks. Radon can then enter buildings through cracks and gaps in walls and foundation.

How to Get Rid of Radon

With Standard Water Control, removing radon is straightforward. Once we install a system, it may only take a few days for our migration system to remove radon from your home or business. 

How Does a Sub-Slab Soil Exhaust System Work?

Our system draws moisture and soil gasses (like radon) from under your basement floor and moves them out of your home.

Is a Sub-Slab Soil Exhaust System Effective in Reducing Radon Levels?

Yes. Our sub-slab ventilation system removes both radon (and other soil gasses) along with moisture.

Are There Any Maintenance Requirements for a Sub-Slab Soil Exhaust System?

The system should be checked on a regular basis to ensure the fan is working properly and the system is moving moisture and soil gasses out of your home environment.
