You deserve the The Best Radon Mitigation Contractor In Wisconsin



Radon Mitigation is the process of removing radon from your home and reducing it to safe levels. This process uses specialized equipment and techniques that our professionals have ready for you. Radon Solutions of Wisconsin covers Madison and the Greater Southern Wisconsin area from Platteville to Columbus.

DIY Radon Mitigation solutions do exist, but unless you plan doing a lot of research and putting in a great amount of time and effort, we recommend you contact us or another licensed professional. Radon Mitigation is not something that you want to have done by an amateur, and an improperly installed Radon Mitigation System could put you and your family in great danger.


The method that will work best for your Southern Wisconsin home depends on how your home is built. Yours will either be built with a full basement, a cellar, slab-on-grade, crawlspace, or a combination of these, and your method will be determined by which of these your home is built on.

  • Sub Slab Depressurization – This is the most common and reliable method of radon mitigation. This technique is designed to lower the air pressure beneath the concrete floor slab by using one or more fan-powered vents to draw air from below the slab, which creates negative pressure under the floor and draws the soil gases through the system and vented above the roof. Additionally, floor and wall cracks are sealed and the sump pump pit is sealed with a removable cover.

  • Crawl Space Depressurization – This method lowers the air pressure in a crawl space relative to the indoor air pressure by using a fan-powered vent that draws air from within the crawlspace. With this system a 6 mil poly sheet is laid over the floor of the crawl space and sealed to the foundation walls and any penetrations. A 3″ PVC pipe is connected and routed to the radon fan either in the attic above or outside and vented above the roof.

  • Block Wall Depressurization – For full basements, a pipe is inserted into the block cavity and attached to the same piping system that serves the other systems. This technique, used in houses with hollow block foundation walls, depressurizes the voids within the concrete block by drawing air from inside the wall and venting it to the outside. It is often used in conjunction with sub-slab depressurization.
