"Radon Gone provided exceptional service from start to finish. They were extremely accommodating, even allowing me to adjust my appointment at the last minute. Ken and his team explained the entire process thoroughly, honored the exact price quoted with no hidden fees, and demonstrated the highest level of professionalism throughout. They worked neatly, kept everything clean, and were genuinely kind and courteous the entire time. Three days later, they returned to collect the commercial radon tester and confirmed that my radon levels were now well below the recommended threshold. After contacting several competitors, it was clear that Radon Gone stood out for their honesty, professionalism, and customer care. I highly recommend them to anyone seeking radon mitigation services."

"It went great. I highly recommend them. They were a pleasure to deal with. The person that came out for the estimate answered all of my questions. The estimate was fair. The work was done on schedule and with no problem. At completion, everything was explained to me. I used their electrician which worked out fine. After completion the radon test showed that my level was now undetectable."

"We had our radon unit installed this week and Josh did an amazing job. He was very friendly, efficient and explained all our options. We would definitely recommend him and your company. Less than 24 hours after being installed our radon levels are now in a safe level!"

"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."

"They're okay. Its pretty good. They stayed late. Overall, they are doing fine. I just did a bunch of research and they seem to be giving me a better quote. They proposed different other than what many people proposed. Other than going through the ceiling, they went through the wall in the side and I think that's helpful. I think price is reasonable. Its not the cheapest. I think I will consider them again."

"We need a quick turnaround after our house tested high for radon during a home inspection. The owner Don was super responsive with the initial quote and was right on top of every from start to finish. Got our installation scheduled right away and blew away the tight timeline we were facing with closing approaching. I hope I only need one remediation system in my lifetime but if I ever had to use his services again, this would be the first spot I would call."

"Tom and Josh arrived on the day and time promised. They were both very polite, professional and worked extremely well together. They explained exactly what they were doing and why they were doing it! They installed the radon Mitigation system and went above and beyond expectations. They cleaned up after themselves. After the job was complete, it looks like it has always been here. What more can you ask? I will definitely recommend DC Mitigation for anyone who needs this service!"

"Jeffrey responded almost immediately to my Angie's List inquiry. He rearranged his schedule to fit us in on very short notice and was available, flexible and communicative surrounding the holiday weekend with our and the sellers' changing schedules. He is very friendly, attentive, experienced, thorough and adept. He listens very well and explains in layman's terms - or whatever terms suit his client. The cost noted includes two furnaces and two air conditioners with the Radon test."

"As a home inspector I readily see radon mitigation systems either already installed or needing to be installed based on radon results from the testing I perform. I have performed post mitigation testing after safe haven has installed mitigation systems and the quality of work as well as no issues of radon being present have I found, would definitely recommend and I would personally hire this company if I needed to install a radon mitigation system in my home."

FAQs for radon gas abatement projects in Greendale, WI

The only way to know whether your home or water supply contains radon is to schedule a professional test. A qualified radon inspector will collect samples, deliver lab-verified results, and explain the findings for $150 to $800. Once you know your exact levels, you and your radon mitigation pro can choose the right system and tackle the problem before it affects your family’s health.

Both roles tackle radon, but they focus on different steps. Inspectors test your home, interpret the results, and determine whether levels exceed EPA guidelines. Mitigation pros design and install the system that lowers those levels. Some companies do both, but the skills and equipment differ, so always verify that the person you hire is properly certified for the specific service you need.

Installing a mitigation unit fixes radon problems by reducing indoor gas levels to established safe standards. A system designed and installed by a mitigation expert, tailored to your home's specific layout and foundation, guarantees effective radon reduction. This expert installation ensures consistent performance over time while safeguarding your indoor air quality.

Open windows and doors do not reduce radon levels because they trigger a pressure imbalance that draws radon-laden air into your home. This practice fails to control radon concentration and can even worsen the issue. An active suction mitigation system provides a proven, safe, and effective solution to reliably reduce radon levels.

Radon mitigation systems generally last between 10 and 30 years, depending on system type and maintenance. Passive systems endure the longest because they have no moving parts, whereas active systems, which use a fan, require fan replacement every 5 to 10 years. System components, such as PVC pipes, seals, and fittings, can remain effective for decades when paired with periodic inspections and proper maintenance.

Radon mitigation systems consume between 300 and 3,000 kWh of electricity per year, depending on fan size and system design. On average, an active radon fan draws 100 to 300 watts continuously, which translates to roughly 876 kWh annually, and adds $30 to $300 to your energy bill each year. Choosing a high-efficiency fan and ensuring tight sealing around pipes helps minimize these ongoing costs.
