Jerome was very professional, timely and informative during the consultation and quote. I didn't get any other quotes because I felt very confident he was going to do a great job and solve the issues I had. Work was done quickly and on time. Great work and I highly recommend.

The project went great. Jerome was very very professional, organized, and clearly an expert at what he does. I'm an Architect, so I work with contractors on a daily basis and have a good basis of comparison. Jerome is an A++. You will not be disappointed with him if you choose to work together.

WI Radon and its owner Jerome were fabulous. He was so knowledgeable about our specific radon mitigation needs. He worked with us closely to customize the system that would best work for us. We were so impressed with the entire process from initial testing to the final inspection of our new system. We would recommend him first if you suspect you have radon issues.

Jerome of Wisconsin Radon & Environmental put in a Radon Mitigation System in our home. His bid was was right in line with the other bids we got. We chose to go with Jerome because he took the time to thoroughly explain the process and he was prompt in responding to our questions. He was very professional and cleaned up all areas he worked in. He ran another radon test after the install and provided us with a detailed report and suggestions for retesting in the future. We feel reassured with the work and system Jerome did with our home.

Every step of this install was awesome. Communication was quick. They gave us a couple options, we chose the better system, they schedule the install quickly, showed up 1/2 earlier than scheduled which was awesome. Conducted 48 hour of testing which was well below the allowed readings. If u are in the need of a radon mitigation system I would definitely recommend them.

Jerome was extremely helpful in educating me on my radon problem, the relevant regulations, and my remediation options. Whether your project is a new install or a repair, he will help you get the best value and design an attractive (as much as that is possible), effective, and compliant system. I highly recommend him!

Of all the contractors I worked with after buying our home, Jerome was by far the most professional, thorough, responsive and flexible. The process of working him was seamless - he gave a few quote options inclusive of upgrades before the work started and scheduled quickly. His quote also included electrical work and permitting, and his electricians office even scheduled the post-work inspection to close out the permit. Can not recommend him and his work enough!

The service was fine. He knows everything about radon reduction. He did a beautiful repair of my radon. It functions very well and appropriates. I would hire them again if needed.

We have hired over 20 contractors over the years for our homes and Wisconsin Radon & Environmental was probably the best overall that we have ever had. I am detail oriented and value contractors with great reviews, great business history, and great communication. Jerome brings all the above to the table. Hire him with confidence and you won’t regret it.

We had a mitigation system installed by Jerome last summer. He was fantastic to work with, and was patient in answering all questions along with providing detailed explanations for different options. He was also highly transparent regarding the cost of of items and pricing. After installing our system he went through the management and care of it, and dropped our radon levels from ~ 12.5 to ~.2. I would recommend Jerome to anyone who needs testing and a system installed, working with him was painless experience.

Very professional and courteous. He did a great installation and took the time to make sure the pipe was unobtrusive and aesthetically pleasing in our home. He was also very respectful of our home making sure everything was cleaned up before leaving. We are very pleased with the service received.

We just had a mitigation system installed by Jerome. He was very easy to work with, he answered all of my questions, he explaned the different options we had for placing our system and had detailed list of where all of our payment was going. After placing our system he went through the management and care of it. He was able to drop our radon levels from 13 to 0.3. Jerome is a very knowledgeable and capable worker. He also went above and beyond and fixed a PVC pipe that was cracked by some other people who did services at our house. I am very humbled by his help, (he also did not tell me that he fixed it.) I would recommend Jerome to anyone who needs a mitigagtion system

Response from Wisconsin Radon & Environmental, LLC
"Hi [Member Name Removed]! I’m sorry to hear the company that installed you’re system did not come back for re-testing! At minimum a passive kit should be left with the homeowner in lue of an electronic test. Unfortunately I have no record of you’re project!Is there any way this project could be attributed to the wrong company???? I’d be happy to re-test you’re system regardless! Thanks -Jerome O’Callaghan Wisconsin Radon and Environmental"

Wisconsin Radon & Environmental, LLC did an excellent job if not a perfect job. Very professional, very neat, excellent price. They cleaned up after themselves leaving the job cleaner than when they started. The testing afterwards showed they did an excellent job in eliminationg the radon.
