"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."

"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!"

"Pick them if you want honesty and integrity. Jeff arrived on time, was honest, professional, and went above and beyond. As it turned out, the work we were told we needed by previous contractors wasn't necessary. Drain tile was already present and functioning in the area in question. Jeff was honest about this and didn't simply attempt to create unneeded and expensive work. He took it one step further and helped me better understand alternative corrective measures we could take. I'm very grateful and can't say enough good things about them."

"They gave us an accurate estimate and stuck to it. They arrived on time. They replaced the large A/C unit outside of the house and the corresponding unit in the basement. They were so professional and did a wonderful job! We were so pleased with the results of their hard work. We highly recommend Dairy Air!"

Radon Detection and Reduction questions, answered by experts

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.
