Step-By-Step Radon Mitigation Guide

Our custom radon mitigation services are effective and will ensure a safe home for you and your family. Scroll through the tabs to learn about how our service works.

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.

Learn More

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.

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.

KiltedtenorKiltedtenor ★★★★★ I worked with Jerome, and he provided awesome services! Competitive price, even after having to adjust some of the quoted prices because of my old and cranky foundation. And he was fast! I was surprised that, all told, it took him probably one full work day, spread out over two days (see the adjustments noted above). If my foundation had been more cooperative, he would have been done in a half a day. Still waiting to see what the outcome will be (to see if we need even more work done), but for what we have done already, Jerome and Wisconsin Radon & Environmental was a genuine pleasure to work with.Response from the ownerThanks T.Awesome to work with you! Sometimes these older homes just need a little more creativity. Doug KubasaDoug Kubasa ★★★★★ Jerome did a great job installing our radon mitigation system.

Thanks!!Response from the ownerThanks Paul, awesome to work with you! Heidi FrenzelHeidi Frenzel ★★★★★ Wisconsin radon did a great job.

Easy to have made the appointment and easy to work with.Response from the ownerThat was a fun one Heidi!Thanks again. Becky LindenbergBecky Lindenberg ★★★★★ Jerome was so professional! After I made my initial request for a test, he was in my building within 5 business days. The radon test was conducted the following week, and we had the results very soon after that. I appreciated Jerome's communication with me throughout the process. I would highly recommend this company!Response from the ownerThanks Becky! Great to work with you. Nick SemenkovichNick Semenkovich ★★★★★ Jerome is a BEAST! We noticed elevated radon levels (that our home inspection missed), and called Jerome about mitigation. He was incredible detail-oriented and efficient. After an initial site inspection, he scheduled us about a week out, and spent about a half-day installing the radon mitigation system. He was extremely meticulous, vacuumed & cleaned up all debris, and did an exquisite job hiding the system behind our existing chimney & color-matching our gutters.Response from the ownerAppreciate it Nick! Rudy knaflicRudy knaflic ★★★★★ Selected Wisc Radon & Environmental company after researching didn't look like a franchise rather a owner operated company with good reviews. This was apparent when working with Jerome. Showed him my measurements (29.0 - purchased my own meter). He explained what was needed, options , and how the system operated. Provided a timely quote. After a few questions, we scheduled installation with a target of 4.0. This was a top notch installation. Radon is now 0.4 way better then expected. Jerome provided a complete report utilizing his metering for a 24 hr period following installation.ThanksResponse from the ownerThanks Rudy. Was really great to knock this one out with just one suction point. Great to work with you and your wife! js_loader
