Radon Mitigation Services Available in O'Fallon, MO

Once you discover your Radon levels exceed the EPA action level of 4.0 pCi/L, installing a Radon mitigation system is one of the most affordable ways of reducing your family’s risk of lung cancer, through Radon risk reduction.

Each Radon mitigation system is unique and designed specifically for your home's needs. Our licensed Radon professionals will examine both the interior and exterior of your home and perform thorough diagnostic testing to determine the most effective placement and configuration of your mitigation system, keeping you informed every step of the way.

RADON MITIGATION SYSTEMS EXPLAINED

Radon mitigation systems are commonly based on Sub-slab depressurization. These systems prevent Radon gas from entering a home by eliminating the toxic Radon at the source, from underneath the home, using a combination of an installed piping system and a Radon exhaust fan.

Normally the air pressure inside a house causes gases from under the soil to be sucked up into your home- not just through cracks but also through tiny pores in the cement slab itself. Radon mitigation systems minimize this, by instead routing those gases up through an installed piping system that exhausts them into a safe location in the atmosphere.

The key to venting the Radon out of the home is the PVC piping which is installed into the slab itself or into an existing sump pump (through a specialized lid), below the concrete floor. Above the surface, the piping is routed to the nearest outside wall, where it runs up along the exterior and exhausted over your roof line. (in some cases, the piping may be routed through an interior closet space or attached garage and through an attic space).

To keep soil gases moving through the PVC piping and into the open outside air, a specialized Radon exhaust fan is installed about halfway up the piping, on the exterior of your house (or when applicable/requested in the attic or garage). This is to ensure constant suction of the gases from the soil under your home.

 

All other obvious Radon entry points such as groundwater sump pits, cracks in basement floors, wall/floor joints, and crawlspace areas, will be sealed when applicable.

Follow Up Radon Testing Ensures Your Mitigation System Is Working Properly

Once your Radon mitigation system has been installed, our technician will schedule a follow-up test to make sure your post mitigation Radon levels are now below the EPA action level.  

Our mitigation systems are guaranteed to reduce the Radon concentrations below the action level of 4.0 pCi/L in any home. In fact, most of the time our Radon-mitigation systems result in Radon levels below 2.0pCi/L.
