"Our radon system fan needed to be replaced and we were able to get that done the day after I talked to this company. Very quick and courteous service and didn't cost as much as we were anticipating."

"I was very pleased with Kevin Leonard.  He was very thorough and I was really impressed that he was over detailed versus under detailed.  I appreciated having all that extra information that I wouldn't have expected.  I got him off Angie's List.  His price was very fair."

"Jon Helton and his son team member Zach were professional and thorough in their inspection while at the same time friendly and easy to talk to and ask questions. In addition to the inspection and samples he took for the lab, Jon gave us several helpful tips and suggestions for making the house marketable. I would definitely use Jon Helton and Home Team Inspection Service again and highly recommend them to anyone needing any type of home inspection, including buyers and sellers."

"He called me 35 minutes before the scheduled period that he would be there promptly at noon, which he was. He did a great job, getting out a couple of stains and was done within an hour. The only caveat is that they are not set up with credit card machines yet so I paid him with a check. Great job!"

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.

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.

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

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