"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."

"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."

"Dave Gardner set us up with an appointment in only two days for installation of a radon mitigation system. Daveâ  s son, Jordan, and his team were very professional, courteous, friendly, honest, and informative in going over their â  game planâ  for our installation system. Our radon level went from 8.9 pre-mitigation, to .4 post-mitigation when we had the test done one week later. Jordan informed us about what he was doing during the installation. We have already referred Gardner Environmental Services to family and friends who also need radon mitigation systems."

"David, at Gardner Environmental Services, professionally performed numerous air sample tests inside our home due to a minor smelling of mold in one spot.Fortunately, his lab resource came back with negative results on each location sample David tested. David was reassuring and pleasant to work with. I would recommend his company, to anyone."

"Called company on Monday and got an appointment for an inspection on Wednesday. That following Monday, the technician arrived and went through each step is sealing off the concrete foundation to the water leak. The fix worked well and was put to the test with the recent record rains. Not one drop of water came into the basement."

"If you want the job done quickly and done right, Safe Haven Radon is it. On time for quote appointment and later scheduled work. Easily came up with a plan to mitigate the whole basement with one fan. VS another company wanted to install 2 fans which would only cover half the basement and we could â wait and see if more work needed to be done.â Safe Haven Radon was the only company that wanted to make sure the radon levels in the WHOLE house would be close to zero. They also guaranteed that once the work was done radon levels would be below 1. Another company told me â you donâ t live in the kitchen, so we donâ t need to test there.â Why would we do all this work and NOT make sure the whole house was safe? Safe Haven Radon did the work in a few days, made sure all the pipes were in unfinished areas, and left areas impeccably clean. He also made sure that the outside fan and pipes were in an area that made sense for the house, near other pipes and A/C, even though it meant doing a little extra inside work. These guys were the best!"

Radon Detection and Reduction questions, answered by experts

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
