"We were 100% pleased with the work done by A1 Radon Services. They were able to schedule us quickly, they arrived right on time, and the installation went perfectly. A short time later we tested again for radon and the number had gone from 9 to 1. We highly recommend. them."

"Ron's a nice guy, knows his business and does a good job. After completion of his work he cleans up the work area before leaving. He guarantees his work and runs a radon test to assure the radon level is acceptable. Thanks Ron and thank you Home Advisor for putting the two of us together."

"We hired Radone, inc. for some follow-up work after a different contractor (Radon Squad, inc.) let us down. Sam did a great job assessing the installation and make the necessary repairs in a timely manner. His communication was excellent throughout. Highly recommend."

"Chris and Randy were the only radon company (out of the three I requested proposals from) that took the time to review our older house and thoughtfully consider what solution(s) may be best for effective radon mitigation. Josh and Tony were punctual, professional, and took the time to listen and respond to my questions and concerns on the day of the install. Would definitely hire again!"
When possible, the pipe is run to the garage, and the fan is in the garage attic.
When there is no way to get the pipe through the interior of the building, the fan and pipe will be outside.

"John called me while I was reading reviews about TJ on angies list. He educated me about radon mitigation. I checked out a couple other companies and decided to go with TJ as they were able to come out the very next day and offered the best price. They arrived at exactly 9 am as they said they would. They evaluated the best method of mitigation for our house and explained their choices. They were done at the time they said they would be and cleaned up after themselves. They left a prepaid radon tester so that we could independently see they had brought the radon level down. Good results came back yesterday! I would highly recommend them!"

"Radiant Radon LLC did a great job. I am a Realtor and was representing a client selling house. The buyer wanted a Radon test done before the closing of the house. We were on a tight schedule and Jon was prompt and professional. He did the inspection and then also did the mitigation. Service was well done and affordable with good communication. Client and buyer were happy with results and the house got sold. Thanks Jon! Had a good experience using your company and will reach out to you again for any future Radon testing/mitigation needs."

Radon Detection and Reduction FAQs, 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.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

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 your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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.
