Radon Gas Mitigation Contractor serving
St. Louis, Springfield & Nearby in MO & IL

radon gas entering home

If there is a chance that radon gas is entering your home, testing is the only way to know if radon is putting you and your family at risk for health issues, such as lung cancer. If the test finds a dangerous level of radon in the home then a radon mitigation system is required. 

Give us a call today to have your home tested or for an estimate for radon mitigation work.

We offer professional radon services in St. Louis, Springfield, St. Charles, Florissant, Wentzville, Warrenton and nearby. 

Factors That Lead to a Radon Problem:

  • The radon concentration of your area
  • Access points for radon to enter your home
  • The amount of ventilation in your home

Important Radon Facts

Certified NRD
  • Radon is a natural gas created by uranium decay in the rocks and soil.
  • It is completely odorless and found in every state to varying degrees
  • The concentration level increases by ten times during the winter months.
  • Homes with crawl spaces face a high risk with radon issues.
  • Low-level radon exposure over time is actually more harmful than short, high-concentration exposures.
  • Radon causes cancer similar to tobacco smoke and asbestos. It causes 15,400-21,800 deaths every year.

Illinois & Missouri Radon Mitigation System Installed

How a MO & IL radon mitigation system works

Woods Basement Systems, Inc. installs and removes the radon from your home by installing a sub-slab depressurization. The radon mitigation system is actually relatively simple to install and simple to understand. 

How Mitigation Systems Work:

  • A PVC pipe runs around your home collecting gases from the soil
  • The pipe runs upwards in your home 
  • A radon depressurization vent pipes the radon up from the soil, up the pipe and safely away from you and your family.

We install interior basement waterproofing systems which means if that you have our basement system installed we can connect the radon mitigation system alongside it so you don't need to have additional materials and costs added to the project. We can save you time, money and provide you with the radon mitigation system you need.
