Testing

A short-term radon test is conducted by Wisconsin Radon & Environmental, Homeowner, or a Home Inspector. Tests are typically conducted with Electronic, Continuous Radon Monitors. These devices are left in the basement for 2 days (Minimum) and log the radon levels over that period. If test results are above 4 pCi/L, Radon Mitigation is recommended.

Wisconsin Radon & Environmental also offers Advanced Radon Hot-Spot Locating. Deploying Multiple testing units in different areas of the home to better determine radon mitigation approach, potentially eliminating unnecessary cost . This can be advantageous if there are multiple radon-entrance locations: Crawl-Space, Sump-Basin, and Slab-On Grade.

Sealing

Radon entrance points are sealed. Primary Radon Entrance points are: The Sump Basin, Major Cracks, and Crawl-Spaces. If existing sump pump is a “Pedestal Style” Sump-Pump, it will need to be replaced with a new “Submersible Style” Sump Pump. This is to ensure a safe seal on the sump basin.

The Sump Basin can be sealed with a simple silicone sealant or can be “Mechanically Sealed” with gasket and bolts/screws for a more secure and professional look.

Diagnostic

Radon Mitigation is all about sub-slab air movement or “Pressure Field Extension”. The more of the sub-slab we can depressurize, the more effective the radon mitigation system will be. Advanced Diagnostics are done to appropriately size radon fan and determine suction-pipe location(s) for proper Radon Mitigation System Design. Diagnostics can be done with a Pitot-Tube and a Vacuum for advanced design or with the desired radon fan itself. This is particularly important when there is no drain-tile on older homes and we are moving air through the soil. The tighter the soil, the bigger the radon fan.

Learn More

Suction

After the slab is sealed and the appropriate fan and piping is chosen, the Radon Fan is wired up and turned on. This begins the Radon Collection/Suction process.

The Radon Fan is the only part of the Radon Mitigation System with moving parts and the most important part of the system.

Learn More

Venting

Radon Exhaust needs to be vented to the exterior of the home. The exhaust point needs to be 2’ above or 10’ away from any window or entrance to the home. Venting can be done on the exterior or through an attached garage. PVC is recommended but “Matching” Gutter-Downspout is acceptable.

Jerome was fantastic. Explained the whole process, talked through the options with me, and I’m really pleased. The install and work, both interior and exterior, is super clean and well done. We had them also add a sump pump backup system as well which I’m glad we now have. All in all I’m happy with the work, the team, and highly recommend going with Wisconsin Radon & Environmental! Don’t hesitate to reach out to Jerome, he’ll get you all set. 🙏

Reasonably priced, efficient, and explained everything. He also noticed that apparently our sump pump was not working (water was over the activation line). Got it working after messing with it for a while, but given the option, we decided to have him replace it for peace of mind at a great price!

I highly recommend Wisconsin Radon & Environmental for radon mitigation. I tested earlier this year and had high readings. Jerome consulted me on how to conduct additional testing and it confirmed we needed mitigation. The quote provided was very detailed and accurate and the crew did a great job installing the system! Our radon readings are now well under 1.0 pCi/L.
