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.

Learn More

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.

Learn More

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.

Glen Brown
Nick visited today and the radon fan was working. Instead of just replacing it suggested I monitor it a week or so as the issue could have been caused by the extreme cold. No sense replacing if not broken. Friendly and customer oriented.
Response from the owner:Thanks for the kind words, Glen! We take great pride and being customer focused.

Great New Installation service, Friendly team members.
Samantha Bethel
Great experience! Jerome gave us a thorough assessment of our sump pump and radon issues, provided suggestions and options to fix the issues, and had choices to fit our budget and needs. The radon mitigation system and replacement sump pump installation were done in a half day. We were very impressed with our new system and already have improved radon levels in our basement. We happily recommend them!

Professional high quality work. The installation was performed with care and all my questions were answered.
Kinan
Very satisfied with my experience with WI Radon and Environmental. Jerome and Nick helped to get me the information I was looking for and ultimately helped to install a mitigation system for me as well as a new sump pump system. This is a messy type of job and they were very clean and efficient despite a rainy, cold day. Very happy and have recommended them to friend and neighbors already. Thanks guys!

Ray Beecher
Jerome was easy to work with and very thorough with explaining the whole process for installation of mitigation in our new home. Levels were in the 20's prior to mitigation. After mitigation installation radon levels have been averaging below 1 for the last 2 months, typically staying between 0.6-0.8
Eric Ragozin

Dennis Kester
I was very impressed with this organization. Jerome was very professional and responsive. He and his team did a remarkable job.
Dianne Obermann
Amazing installation- we are so happy.
4 inch PVC, up from the floor, over the basement, up through the house wall ( supported at 5 feet) to attic, over 40 feet through a hot attic to the attic platform over the garage and out the garage roof. Corner basement suction readings were nothing less than -8.0.
The new sump pump lid exceeded what we wanted. Was not cheap but—- if you want a first class installation, hire Jerome and team.

Response from the owner:Thanks for the awesome review for your radon mitigation project in waukesha wi. That was a very long run, but completely doable with the right size fan and the right size radon fan. The advanced pressure diagnostics and pressure field extension measurements also helped us determine which direction to go.
None of this would’ve been possible without the awesome lunch that you-supplied for fuel.Thanks again!

The radon mitigation proposal I received from Jerome was the best in terms of tech details and cost. The project was done to craftsman work standards. Now the radon level is consistently less than 1 pc/l
Response from the owner:Thanks Robert! It was great to take care of your radon mitigation system install in Richfield. A nice and easy route through the garage. Thanks again for the opportunity.

We had a new radon system installed by Wisconsin Radon & Environmental. Jerome and team did a fantastic job with great care. They also communicated extremely well and were very professional.
Response from the owner:Thanks, Matt! It was great to work with you on this project.
Prem Krishnamoorthy
Professional, upfront and easy to work with. They did a great job setting up the system. Jerome addressed mine and my neighbors concerns as well. Highly recommended.
Response from the owner:Thanks Prem! Glad we could conduct pressure field extension diagnostics to determine that a smaller quieter fan could be used to satisfy your mitigation needs and your neighbor‘s noise concerns.


Great to work with you and your family!
Robert Kowalsky (Bob)
Wisconsin Radon & Environmental was great to work with from the beginning. Jerome came by and he spent time explaining the options that would work and his view.on their effectiveness. On installation day he ran into issues and recommended changing the approach. Again he described options with his view of each options effectiveness. I chose one and he moved forward which required them returning for another 1/2 day to complete. We started with a 9.7 radon level. Since his remediation we are averaging under 0.4. Can't say enough good about the entire experience.
Response from the owner:Thanks Robert. There’s always a way!
Joe Belanger
Very professional, very thorough, highly recommended. Would not consider anyone else.
Response from the owner:Thanks Joe!

Colette Spitzer
We had a new radon mitigation system installed by WI Radon & Environmental a few months ago and are very pleased with the results! Jerome was a consummate professional throughout the entire process. He exhibited clear communication, as well as careful craftsmanship while he installed the system. My husband even appreciated how he precisely matched the color of the device exhaust piping with that of our gutters. Overall, we feel this was a wonderful investment in the best interest of our family. Great job Jerome!
Response from the owner:Thanks Colette! Really appreciate the kind words. glad the process was smooth and professional. We even get lucky every once in a while with a perfect match on color for gutter exhaust systems on radon mitigation ; )
Amazing Home. Thanks!

Outstanding experience working with Jerome. Quick turnaround to obtain an estimate for radon mitigation services. Well explained and detailed. Included optional items, if we desired to upgrade the fan, etc. No pressure at all! Was able to schedule within a few weeks. Work was done very professionally.

Jerome stopped to replace an outside fan unit that had moved on after seven years of use. He was friendly, professional and had the job completed quickly. I would have no problem with recommending his services to anyone who was in the market for them.
